you're not a nerd for knowing the square root of 4^2 plus 3^2 is 5... although the first guy is a fail for thinking 16 + 9 = 27 lol
Also the 3, 4, 5 triangle is one of the "magic" triangles. In more advanced math you'll always be happy when you get the sides of a triangle which are multiples of 3,4 and 5 (because then you know it's a right angle triangle :P)
for example:
if the sides are 3 and 4, the hypotenuse is 5. (x1)
if the sides are 6 and 8, the hypotenuse is 10. (x2)
if the sides are 9 and 12, the hypotenuse is 15. (x3)
This allows you to do trigonometry so much easier...
I am using my calculator even for easy counts - I can do it myself, but I can easily loose concentration and if I fail, it will make mess in large calculations. Mistake at the beginning changes the whole result...
Well known.
And BTW x= √27
Actually, the math nerd I am, I have to point out that x=5.
we had that with Math last year ^^

We learned that C^2=A^2+B^2=3^2+4^2=9+16=25, and ratix (Or however you call it) of 25=5 so C=5 :)

ok that's the borring fact kids! don't tell this at home!
And by the way, another triplet is 5, 12, 13.
Funny how I never thought of that throughout all the math classes I was in during school.
Good one.
(really) Old but gold.
