Due to someone asking for math homework, I was shocked at the amount of incorrect answers.

I'm curious here how 'skilled' at basic math a lot of people are here.

Please don't share answers in the posts below, I'm actually trying to see how 'smart' some people think they are.

are you serious???? This is too easy ... let me find better example to check our math basics :) ... just give me a minute ;]

better example to check for math newbies :D :) :
4¹+(5+5)-7⁰+(33+2)²*2=

Just because something is easy for you doesn't mean it's easy for others.

(100%)
everyone is smart   :D

I am pretty sure this example was too easy ...

:) it was like for 9 years old kid ...
We are bitcoiners :) Give us something harder!

HAHAHHA O M G , i just wanted help ... This was to easy , but
not all people are smart for maths... When I see someone in trouble
my only and primary goal is to help. Maybe i shoulednt do that anymore
 :/ I will delete post above

Nobody got it wrong, LOL!


2455?

3easy5me

erm... WRONG :D


:) :)  you were close :P perhaps you mistake + with - :P

4+10-1+(1089+2*33*2+4)*2=
13+2442=2455

I HAVE SOMETHING ONLY FOR ELITE! :

Find the right 'x'.

x= z*y+v
z = sqrt(845+0.121)*33)
y = 2*sqrt [( sqrt(9768/1) * 4/sqrt(9768/1) )]
v = 256⁰

The answer will make you feel much better :)

and why it is that?
(33+2)²     =    1225 :)
sqr(33+2) = 1225 no doubt.
4+10-1+2450 = x  :)

4 + 10 - 1 + 35 * 35 * 2 = 2463

35 * 35 = 1225
1225 * 2 = 2450
2450+10+3=2463

P.S. 1089+2*33*2+4 = 1225

Because it's a binome (dunno the English word for it).

(a+b)²=a²+2*a*b+b²

(33+2) * (33+2) = 1225

nothing will change that.

If it was 35², then you would be right.

:) Please :) Count it again and tell me is the right answer was 2463? :)

Crap :)
The school system has destroyed my brain. I'm handicapped without a calculator.

That reminds me of another one, just as "easy" but sort of complicated in length (was 6th grade during some fun lesson by math teacher).

Replace every letter by a cipher so it becomes valid:

 ;) ??? ;D

I'm one of the correct ones :D It wasn't hard though, to be fair.

You only have to use the binomial formula when there is a variable in it. Sure, it also works with numbers, but it is unnecessary work. The answer is 2463.

I was the second person to get it wrong.

I used to be very good at maths but I honestly have no idea how to do this, even after seeing the correct answer.

Use it or lose it I guess :/

Looks like it's not so any more. :D

(83.3%) now  :'(

Three people actually missed this question. Wow. I have a feeling a scammer could make a fool of at least 3 people here ;)

The correct answer is "15"

Now if someone can please explain to me how to calculate the hash of the next block in my head. 

I gave it shot and arrived at 15 to be the right answer though i am the perfect mathematician.

4¹+(5+5)-7⁰+(33+2)²*2 = 4 + 10 - 1 + 35² * 2 = 13 + 1225 * 2 = 13 + 2450 = 2463
I didn't need a calculator for this one ;)



z = sqrt(845+0.121)*33) = sqrt(845.121*33) = sqrt(27888.993) =~167
y = 2*sqrt [( sqrt(9768/1) * 4/sqrt(9768/1) )] = 2*sqrt [( sqrt(9768) * 4/sqrt(9768))] = 2*sqrt [4] = 2 * 2 = 4
v = 256⁰ = 1

x = z*y+v = 167 * 4 + 1 = 669

Didn't need a calculator for this one either.

Without parentheses, everything starts at 0. FFS.

"You shit got right that!"

I got 9 trying to do this in my head real quick ???

15 is my guess.
