If you think this is false, I pity your pathetic maths education.

[Anonymous No.4800488]

that's pretty awesome

[Anonymous No.4800491]

I do not think 24 is the answer.

[Anonymous No.4800497]

Wait wat. plox explain how this isnt 24.

[Anonymous No.4800498]

4!

nice

i don't suppose it will be right if I wrote the answer in binary too?

If you can't solve this I pity your pathetic math education.

[Anonymous No.4800499]

It looks like OP doesn't understand the difference between <span class="math">:[/spoiler] and <span class="math">\div[/spoiler].

<div class="math">40 - 32 : 2=40 - 16=4!</div>
<div class="math">40 - 32 \div 2={40 - 32 \over 2}=4</div>

Second one is wrong. Moron fag is moron.

>>4800497
4!(or 4 factorial) means 4*3*2*1, which equals 24

lel
you just went full on retard
":" is not a symbol (but could be used as 'ratio')
The meaning of the other one, as well as "/" is division. Division binds stronger than subtraction.

[Anonymous No.4800544]

4! = 24.

Don't see where the problem is.

[Anonymous No.4800560]

>>4800500
i see what you did there

[Anonymous No.4800593]

>>4800500
This guy.

[Anonymous No.4800600]

Wouldn't brackets be required for it to be 24?

[Anonymous No.4800615]

42-32/2=4!
8/2=4!
4=4! :D
You are right, OP.

[Anonymous No.4800625]

>>4800485

You're so smart and nerdy OP XD! You should bake a cake that is shaped like the Greek letter Phi and post it on Reddit to show how nerdy-and-yet-cool you are! Who would have guessed that the exclamation point denotes a factorial? You must have done well in AP calculus to know that!

[Anonymous No.4800630]

>>4800500
I guess the left clause equals 2, as for the right side I can't be bothered looking up hyperbolic functions.

[Anonymous No.4800635]

>>4800500
The limit is 1, the pythagorean identity is 1, so it's just equal to 2. What a contrived way of writing it though.

[Anonymous No.4800667]

>>4800635
Contrived? Not at all my dearest fellow! Mathematics is all about clarity, and to write 1+1=2 is simply bad taste.
Picture related.

[Anonymous No.4800671]

this is true

[Anonymous No.4800679]

>>4800667
This is actually funny. But it makes me sad that I haven't studied series yet.

[Anonymous No.4800685]

[Anonymous No.4800688]

>>4800667
haha oh wow
is that for real?

[Anonymous No.4800714]

Might as well represent it as the gamma function applied to number 5.
You lack scientific haughtiness, OP.

[Anonymous No.4800737]

>>4800485
Haha, that is actually pretty clever.

If they are quite stupid, are not doing order of operations correctly, and think that it is just a exclamation point after the 4, then they will agree with OP.

Correctly doing order of operations, but not spotting the factorial, they will disagree with OP.

Correctly doing order of operations, and also recognising the factorial, they will agree with OP.

The stupid and clever people agree with each other, but for the wrong reasons.

Those in the middle are the only ones who will disagree.

40-32/2=40-16=24

4!=24

Where is the problem?

[Anonymous No.4800751]

I once made a similar joke at my office.

Nobody got it :(

[Anonymous No.4800754]

>>4800751
Really? Nobody at your office knows what a factorial is?
