15 is my guess.
I got 9 trying to do this in my head real quick 
Without parentheses, everything starts at 0. FFS.
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
:
41+(5+5)-70+(33+2)2*2=

:41+(5+5)-70+(33+2)2*2=
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
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

The answer will make you feel much better
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.
I gave it shot and arrived at 15 to be the right answer though i am the perfect mathematician.
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.

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

Looks like it's not so any more.

Neat, looks like 1 person missed it. I wonder who it was. Come on -- come out and admit it. 
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 :/
Because it's a binome (dunno the English word for it).
(a+b)2=a2+2*a*b+b2
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. (a+b)2=a2+2*a*b+b2
I'm one of the correct ones It wasn't hard though, to be fair.

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).

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

P.S. 1089+2*33*2+4 = 1225
Please Count it again and tell me is the right answer was 2463? Because it's a binome (dunno the English word for it).
(a+b)2=a2+2*a*b+b2
(a+b)2=a2+2*a*b+b2
(33+2) * (33+2) = 1225
nothing will change that.
Because it's a binome (dunno the English word for it).
(a+b)2=a2+2*a*b+b2
(a+b)2=a2+2*a*b+b2
4+10-1+(1089+2*33*2+4)*2=
13+2442=2455
35 * 35 = 1225
1225 * 2 = 2450
2450+10+3=2463
P.S. 1089+2*33*2+4 = 1225
