Why would it be?
right it’s 2.52.50
according to the gas chromatigraph, the secret ingredient is…
275, cuz math is hard
225 * 2 = 450 ≠ 550. I initially thought it was 550 which makes sense since I was a math major. its been 3 years since I actually studied arithmetic leave me alone.
This doesn’t bother me. It would bother me if 220 * 2 = 540. The equation in this meme should be something like 11 * 11 ≠ 111
275
Proud of you guys.
I propose to the Math commission to change this and 77+33. Who’s with me?
boo im not with you i want math to be painful and people to suffer boooo
:<
What a nightmare…
Gonna leave this here for those who need it. It’s surprisingly fun to grind arithmetic skill.

Is the joke that you suck at maths?
The joke is that system 1 thinking is not as accurate as system 2 thinking.
What are these systems of thinking? Never heard of them
You’ve gotten a more full answer, so I’ll elaborate on the “bat and ball” example I mentioned elsewhere. There’s a famous puzzle: a bat and ball together cost $1.10. The bat costs $1 more than the ball. How much does the ball cost?
System 1 thinking results in the answer $0.10. Because $0.10 + $1 = $1.00. But the correct answer, which can only be arrived at in system 2, is $0.05, because the question isn’t actually about $1.10 - $1.00, but x+(x+1)=1.1. That’s not a problem system 1 thinking can do though.
Because $0.10 + $1 = $1.00
I have bad news…
my system 1 thinking: the sum of money is about 1, so each costs 1/2, but the bat costs 1 dollar too, so the bat is 1+1/2 = 3/2, and ball is 1/2. simples! wait… i forgot the .10. so bat costs 3/2.10 and 1/2.10 i guess
my system 2 thinking: i must do gaussian elimination!
Basically there’s a rapid response cognitive process that you don’t even have to consciously decide to apply that’ll give you a quick answer to posed questions. Anything where the answer is something you’ve mostly memorised and don’t need to calculate or deduce, such as ‘what’s your name?’ or 2+2. That’s system 1.
System 2 is anything you have to consciously apply a thought process to find it. Brains are lazy and like to conserve energy, so you need to decide to do it.
Obviously, what falls into which system depends on your personal habits and experience. Someone who works with numbers a lot, such as a waiter or a bookkeeper, might have the post question fall into category 1, but the average person will have to decide to solve it consciously, even if it only takes a split second.

You shouldn’t need system 2 thinking for that at all …
You obviously do. It’s a pretty similar example to the classic ball & bat problem. It’s not hard maths, but system 1 basically doesn’t use maths at all. It’s pure instinct.
How would that obviously be the case? I work with numbers a lot and immediately knew 550/2 = 275, didnt need to think for the fraction of a second. The systems are not equal across different people, every mind is unique.
Small example: Would you consider 10/2 = 5 system 2? I think most people wouldnt, but ask a 1st grader and they would probably need to think for a few seconds.
If you have studied or work with numbers, components shift from system 2 to 1 depending on your experience.
I, too, just had to glance at 550 to know it was 250+ since 500/2=250 and that fact is just baked in there somewhere without me needed to think about division. And since it’s the same thing again with the 50, it doesn’t take more than a fraction of a second to do 250+25…
But my system 1 never thought 225.
What systems are you talking about?
It comes from here: Thinking, Fast and Slow
TIL the book is pretty recent-ish. I thought I read it ages ago.
Basically “System 1” is intuitive gut responses, while “System 2” is anything that takes conscious effort to think through.
For a lot of people, 550/2=225 might look right at first glance (System 1) and only with conscious thought at what that division actually evaluates out to would they realize that 500/2 on it’s own is 250 and therefore the answer is actually 275 (System 2)
No you don’t, it only took one look to see that half of anything bigger than 500 needs to be at least 250.
Yes. Same as: 225×2 is not 550. Well, duh, obviously
Maths is hard

White text on a teal background:
Guys I have bad news.
550 ÷ 2 is not 225.
Checking the comments for the answer. I couldn’t figure it out. We can either up our educational investment or give every citizen a Chinese friend.
500/2= 250, 50/2=25, 250+25=275
You must not be American.
That’s the common core math used in the US that people got so upset about (because it was different from how they learned math)
Oh… that’s how I do math in my head anyway?
Which is why it’s being taught that way now instead of the old methods. It’s a more intuitive method.
Wrong, I was born and raised in this toxic shithole.
