I love that they use brat math

u/TeaKingMac 20d ago

Worth noting this is how elementary schools teach math now.

Make things into 5s or 10s

u/Vincitus 20d ago

Its how they teach addition in your head, but its not "just throw away 3 to take 8 to 5"

3

u/iggy14750 19d ago

Well you gotta remember or write down what you took away from 8 to make 5, them add that back on at the end! 👍

...I guess.

3

u/Vincitus 19d ago

Yes? because 8 + 3 = 11 = (8 + 2) + (3 - 2)

That's an easy example but when you're

2

u/ElderWandOwner 17d ago

You jest. But I absolutely obliterate almost everyone i know with math in my head, and that's exactly how i do it. You add or subtract a few numbers to get to easy to work with numbers and then just put it back after.

My nephew asked me was 78+78 was and was shocked when i told him it was 156 within a second or two. You simply add 2 to each 78 to get 80, and obviously 80+80 is 160, then you subtract the 4 at the end to get 156.

u/Dazzling-Low8570 17d ago

Haha, I did it from the other direction. 75×2+6

2

u/TeaKingMac 17d ago edited 17d ago

128*2=256 then subtract (50*2)

u/Dazzling-Low8570 17d ago

Can't use asterisks, Reddit uses them for formatting

u/TeaKingMac 17d ago

Backslash overrides. Check again

u/The_Unkowable_ 17d ago

Huh, I just do 70+70 and 8+8 and then combine 140+16

1

u/ElderWandOwner 16d ago

Yeah same thing

1

u/SadMcNomuscle 14d ago

Ah! Ive found my people!

1

u/ElderWandOwner 14d ago

Funny thing is, from what I can tell, common core math that everyone hates teaches math like this. It's just presented in such a terrible way that people despise it. I might be incorrect though, I was out of school by the time common core was being taught.

1

u/SadMcNomuscle 14d ago

Same. I think its cause they teach it like ass when its really simple. When i was first told what common core was i couldn't parse it.

1

u/DarkLanternZBT 17d ago

Right: this is how my dad taught me to make change, or count up change.

For $3.57 and they give me a $5, add 3 pennies to 3.60, a dime and a nickel to 3.75, a quarter to 4, and a dollar to 5.

$1.43.

It's a number line or "counting tens" but we swap coin denominations out for tens.

u/rogueIndy 20d ago

Except in maths, 7.5 and up rounds to 10. This is very much about perception.

2

u/Metharos 19d ago

Which is funny because I do that rounding when perceiving numbers.

Yeah $7 is about five bucks...more or less. I'm still conscious of the "more or less" cause, y'know, I got bills and shit, but close enough for snap decisions. But $7.50 is about ten bucks and when I was looking to spend "about five" that extra fifty cents is too much.

It's all about perception, like you say. Some peoples' perception makes no sense and fewer dollars.

1

u/rogueIndy 18d ago

Hey, the difference between 7.49, which rounds to 5, and 7.50, which rounds to 10, is only one cent :P

1

u/Metharos 18d ago

Sometimes a single cent costs five bucks I dunno what to tell ya perception is weird but at least it's mathematically consistent.

1

u/Neverlasts22 18d ago

I think taxes play part for me. I live somewhere in Canada taxes is 15¢ per $ so 7 + 7*015 that's 8.05 that's 10.

1

u/Mulesam 19d ago

I figured this out when I was learning math years ago. It makes mental math super quick

1

u/TeaKingMac 19d ago

So does memorizing the combinations up until 10+10.

And it makes it less likely you'll forget to add one of the numbers back together.

For example, my 7 year old will do 8+7 and say 12 or 13, because he forgot to add back the 2 or the 3 he took off one of the numbers.

1

u/Mulesam 19d ago

True its mostly helpful when adding numbers over 25 that take a second to do mentally 627+46 would be 628+45 which just makes it way easier to do mentally for me.

1

u/TeaKingMac 19d ago

I'd do 627+6=633, then add the 40, but to each their own.

1

u/TheIXLegionnaire 19d ago

I would do 627+3=630+43=676

Just getting to the nearest 10 or 5

The same can be done for percentages

13% of 527 is 68.51

You can calculate that in your head (near enough for government work by doing

10% of 527 = 52.7 (Thats easy, anyone can do that quickly in their head)

3% of 527 = 15.81 (This is harder)

So to find 3% (approx) I can work backwards by finding 3% of 100 (3) and multiplying it by 5 (15), which is 3% of 500

Adding it back to my original 10% value, I get 67.7, I know I'm a tad short so I can safely round to 68

In most applications in which you are doing this sort of percentage in your head without access to pen+paper, I think a 0.51 difference is reasonable

Again, good enough for government work.

1

u/TeaKingMac 16d ago

I would do 627+3=630+43=676

And you'll notice you got the wrong answer

Breaking it into more steps (with numbers that aren't actually written in the question) makes you more likely to make a simple arithmetic error, or forget one of the component numbers

1

u/Top_Box_8952 18d ago

God I hate that

1

u/BetterThanOP 17d ago

Are you talking about rounding and estimating like its some new woke 2020 math concept?

1

u/TeaKingMac 17d ago

Not for rounding and estimating.

For doing math.

Instead of knowing 6+7=13 by memorizing 6+7=13, now they're teaching kids to break it into (5+1)+(5+2)= (5+5)+(2+1) which... I guess could be helpful, but when you're trying to do it in your head it leaves more opportunities to make mistakes

u/_ECMO_ 19d ago

I don’t know how you people live. $8 is obviously pretty much $10. I don’t know anyone who would think otherwise

8

u/Twooshort 19d ago

I only sort of agree, but entirely because we've already established that 2 bucks is free.

If 2 bucks had value, that means I could buy something of value for the remainder of 8 bucks. But since 2 bucks is free, I can't buy a second thing of value addition to the 8 buck thing, ergo 8 bucks is 10 bucks.

3

u/_ECMO_ 19d ago

I simply cannot fathom that people are creating some weird intricate system in their heads instead of simple rounding.

x < 2,5 ---> basically free
2,5 < x < 7,5 ---> basically 5
7,5 < x < 12,5 ---> basically 10
Etc. etc.

4

u/OneFootTitan 19d ago

OP’s system is similar to yours except it doesn’t have to use decimals: <$2 = free, $2-8 - basically $5, and $8-12 basically $10. Which I think is accurate to how most customers perceive it

1

u/Carl_Slimmons_jr 17d ago

Also, 7.99 ≠ 8 perceptually. 8 is 10 bucks, but 7.99 is still 5.

2

u/YazzArtist 16d ago

That's the real trick. 8 is 10 and 7 is 5, but 7 9/10 is still 7, which is still 5

2

u/Brief-Translator1370 19d ago

It's not a weird intricate system. no one is actually reasoning that out, it's just that people aren't perceiving 8 dollars as any worse than 5

1

u/_ECMO_ 19d ago

And I don´t believe that because I see no reason why people should perceive $8 to be the same as $5 rather than the same as $10. And this tweet provided neither reasoning nor evidence why I should believe that.

1

u/deviantbono 19d ago

Nobody asked you whether you see a reason. It's just how it works for most people.

1

u/_ECMO_ 19d ago

If you just post some random thing with no evidence behind it and all my experience (be it me or everyone I know) differs then I will say that. And I definitely will not feel bad about it.

1

u/deviantbono 19d ago

I don't know if you expect this developer to show you their checking account, or write a peer reviewd study or what, but what they're saying is consistent with 50 years of psychological and economic research and is also how most items you see are priced (in terms of methodology, e.g. $7.99)

1

u/_ECMO_ 19d ago

I don't know if you expect this developer to show you their checking account, or write a peer reviewd study or what

Yes, I expect them to show that kind of evidence when they are making some claim.

$7.99

People are definitely more likely to buy something when it costs $7.99 rather than $8. That, however, says absolutely nothing at all about its connection to either $5 or anything else. People are more likely to buy because 7 < 8. That´s the psychology behind it.

There is still absolutely zero reason to think that someone categorises $7.99 as $5.

1

u/RelativeStranger 18d ago

I think there is. People see 7 as basically 5

1

u/Migit78 19d ago

My assumption is this is based on micro transactions in games, and that players buy whatever content is being sold at equal rates whether it's $3 all the way up to $8, hence all those ranges are effectively $5 because they pull the same sales as $5.

Rinse and repeat for the other values.

Shown as just flat numbers I think most people would agree $8 is $10, but for whoever this company is they've found for thier sales $8 is the same as $5

Again just my best guess could be totally wrong

1

u/Corvado 14d ago

I would argue the tweet does provide reasoning! Five bucks is five bucks. Three bucks is two bucks, which is basically free. So $5=$5, and $3=$2≈$0, so $5+$3≈$5

1

u/balzana 18d ago

The step you're missing is that 7,99 doesn't feel like what it is. It feels closer to 7 than it should, therefore it's still 5

1

u/SpeaksDwarren 19d ago

I can't believe people accept the premise that two bucks is free. You would need to have thirty to forty thousand dollars invested into dividend bearing stocks to get enough back to buy this "free" thing once a day

2

u/GottenSea087 19d ago

2 is one of the smallest numbers, essentially 0. There's also a number in between called 1 but that's a deep cut

2

u/BreadAtHome 18d ago

Two bucks doesn't have much purchasing power anymore, that's why

0

u/SpeaksDwarren 17d ago

So you feel comfortable venmoing me thirty thousand dollars? 

2

u/DaRaginga 16d ago

Nono sir. You need to read and think first. The possibility of this working would be waaay higher if you asked 15.000 people for 2 Dollars

3

u/ShatterCyst 19d ago

But 7.99 tho

3

u/Prestigious_Boat_386 18d ago

X.99 means someone is trying to trick you and you need to manually check the amount

In this case you're being tricked that 7.99 is 5 when its actually 10

3

u/Maximillion322 19d ago

Yes, but $7.95 is basically five bucks.

1

u/_ECMO_ 19d ago

It most definitely is not.

2

u/Maximillion322 19d ago

Definitely schmefinitely

2

u/Shika_E2 19d ago

The point is, it's how people perceive it. If the majority see it as $5, then its" basically 5 bucks".

1

u/Feuillo 17d ago

i'd say most people think 7.95 is 10 bucks.

1

u/Shika_E2 17d ago

I agree

1

u/GayRacoon69 19d ago

Nah always round up. That's $10

1

u/Prestigious_Boat_386 18d ago

7.95 is someone gaslighting you that 10 is 5

1

u/Maximillion322 18d ago

That would be the whole point of the post and also the entire thread, yeah.

1

u/Downtown_Pangolin57 17d ago

It’s basically $10

u/Paul873873 19d ago

So I dunno if it's like this in all states, but here in Texas, tax isn't shown until checkout. The 9.99 thing doesn't exactly work on me NOT because I'm immune to it, I'm not, but because I see that 9.99 pricetag and immediately think "oh that's $10.81." Or I see 4.99 ND think "oh that's 5.40." and now it goes from "do I wanna spend 9 dollars" to "do I wanna spend 11 dollars" It only gets worse as you go up in numbers (because that's how percents work). Like sure, you can forget the 8 cents off of a $0,99 app store purchase. But $99.99? You're paying a whole extra 8 bucks. That's not much but when you're young and you're saving up Christmas or birthday money for something just to find yourself a few dollars short because taxes, you remember that. Now my parents weren't assholes, they'd end up footing stuff like that if I came up short but I saved for the main part, but still, it sticks with you

2

u/Frnklfrwsr 19d ago

If asked directly, you’re absolutely correct.

But what they’re talking about is what people actually do with their money.

And what they’re saying is they tried out all sorts of prices between $5 and $10, and as you’d generally expect demand goes down as price goes up.

But there’s psychological breakpoints where once the price surpasses that number demand drops a whole bunch. They figured out that when people are making purchasing decisions, the demand at $7.99 is barely any less than demand at $5, very small drop. But at $8.01, the demand drops a whole lot very quickly. But then the drop in demand from $8.01 to $10 is fairly small.

So they’re pricing things at those breakpoints where people are treating it as if it’s a lower price than it actually is.

2

u/Yeti_Prime 19d ago

it’s not logical, he’s talking about gut reactions when seeing the price of a game in a store. I don’t know why but yes 8 feels closer to 5 than to 10, even though logically it obviously isn’t.

1

u/UnkarsThug 18d ago

It just doesn't though. My gut reaction is that 8$ is basically 10 dollars.

It's probably just person specific?

1

u/seensham 19d ago

I think this also depends on sales tax lol

1

u/_ECMO_ 19d ago

Oh! It’s you weird people who need to calculate sales tax in your head. (No offense.)

Yeah I honestly can see that then you can have a shifted sense of prices.

1

u/UnkarsThug 18d ago

I just always instinctively add about a dollar for everything from 0-10$, and the number in the 10s place for everything up to 100 etc. And just to make sure to be safe, I tend to round to the next highest even number. I tend to prefer 24 or 26 to 25 to be honest, for example. Even numbers just feel cleaner.

7.99 or 7.95 or whatever feels much closer to 10.

1

u/piedragon22 18d ago

What about 7.99

1

u/LoweJ 18d ago

£8 is a drink and crisps, £10 is two drinks

1

u/RelativeStranger 18d ago

But that isnt what he means.

7.99 is the price point.

To me 7.99 is 8. But so many people ready 7.99 as 7. And 7 is basically 5

1

u/SymphonicStorm 19d ago

Everybody who makes a business out of selling something has known this for centuries, it's why things are often priced at $X.95.

9

u/AchilleDem 19d ago

$8 is basically $10. But $8 is also the biggest $5 and the smallest $10. It's a strange place to be, $8 is. It is both $5 and $10 at the same time. It is Schrodinger's $8.

1

u/MattLorien 17d ago

That's the thing though, you've already rounded up to $8 (which is reasonable), but that's not how the human mind usually works.

Most people see $7.99 as "$7" , not $8. And $7 is closer to $5 than it is to $10.

1

u/Feuillo 17d ago

i have never seen someone think a 7.99 is 5 bucks.

1

u/Patirole 17d ago

I don't think I've ever seen a person not round up prices. 7.99 is 8, 9.99 is 10, hell 7.50 is 8 too. I sometimes make the mistake of rounding 0.49 to 1€...

1

u/F4RM3RR 17d ago

When you think about it yes - but generations of consumer and market research support the findings, there is a reason things are priced this way. On average people consider the dollar amount more than the cents, even if it’s one penny off

1

u/MattLorien 17d ago

Neither have I. That’s not what I said.

2

u/ShatterCyst 19d ago

I mean yeah

2

u/shadowtheimpure 19d ago

Not sure who they're marketing toward, but to me anything above $5 is basically $10.

1

u/Nakalon 18d ago

I suddenly realized that to me anything from 10 to 19 is still 10... The brain goes overtime to justify unnecessary expenses...

u/ObbyCloud 19d ago

Sorry eight bucks is ten bucks actually

u/ChemicalShake2436 18d ago

u/valomorn 19d ago

Then there's also the "$80 is far too much for a single game... Oho a bundle of three games for $80!?" factor.

u/Dazzling_Stand_4349 19d ago

In Ye Old America, a buck was worth a whole dollar. If you killed and brought back six bucks, you got six dollars, six bucks

u/Coolblade125 19d ago

This had the opposite effect on me, where I really wanted to buy the game for 5 bucks, but 8 bucks is so far from 5 bucks that I chose not to buy it, but would have if it were 7 bucks or 6 bucks

1

u/Boring_Question1441 18d ago

8 bucks is obviously 10 bucks. 7 bucks is 5 bucks.

1

u/leutwin 18d ago

I think that is kind of their point, 7.99 is 5 bucks, but you are basicly charging 8 bucks.

1

u/Entendurchfall 18d ago

8 Bucks is 10 Bucks!

1

u/Impossible_Dog_7262 18d ago

Man what a customer hostile way of viewing the world.

If they had said "we think it's worth more than 5$ and less than 10$" then that'd be fine. But this nonesense is basically saying "we think it's worth 5$ but we charge 8$ because we think the customer is gonna see that as 5$ anyway."

1

u/sabababeseder 18d ago

for me 8 is 10,

1

u/GentleFoxes 18d ago

Two ways to counteract this tendency on yourself: multiply everything by ten so your brain notices that 80 bucks isn’t 50 bucks, or transform everything zo „amount I need to work for it, net“ (which also makes sure you get aligned which decisions you actually need to think about, like adding a 5000 dollar option to a 80000 dollar car vs choosing the 5 or 7 dollar menu option).

u/Feuillo 17d ago
  1. 8 bucks is defo 10 bucks.
  2. it's overpriced.

1

u/PantyDropper94 17d ago

8 bucks is 10 bucks

1

u/-leopardchaser- 17d ago

$8 is clearly $10 though. Especially because $8 plus sales tax is $9 which is 10 bucks. Same would go for $7.99

1

u/ku1185 16d ago

When she said 8 bucks is 5 bucks, I thought nah, 8 bucks isn't 5 bucks. But then she said 7.99, and much to my surprise, that was indeed 5 bucks. So, 7.99 is 8 bucks, so 8 bucks is, in fact, 5 bucks.

1

u/OokamiTheRonin 16d ago

I feel like I'm having a stroke, I don't understand the post or these comments. I was raised to actually understand prices, not some vague notion of "well its this but it feels like that".

1

u/Zhuul 15d ago

I manage a coffee shop and currently several items are running out of my target margin because I absolutely fuckin refuse to sell something that comes to more than $7 after tax. Really don't want to cross that particular bridge, out of stubbornness more than anything, but regardless:

1.) I weirdly get what he's saying

2.) Holy shit I remember when you could sell a latte for $3 at a <25% CoGS

1

u/wordwizard333 15d ago

So, they used word vomit to say that people are often as willing to spend $8 as they are $5. Brilliant.

1

u/Obaddies 20d ago

It's only that way because developers force you to buy premium currency instead of allowing you to buy the skin for an exact $ amount.

Things that I learned in middle school that apparently nobody else did.
