All Numbers Are Equal   
5 c+ C3 _% \) J% L7 ]* ?Theorem: All numbers are equal. Proof: Choose arbitrary a and b, and let t = a + b. Then

7 q  g7 Z6 k+ l2 u" O) oa + b = t
(a + b)(a - b) = t(a - b)
- H7 H: I. `% E9 u. E- J( _" Sa^2 - b^2 = ta - tb
a^2 - ta = b^2 - tb
# Q5 m& _; [4 Z5 \8 A, Ja^2 - ta + (t^2)/4 = b^2 - tb + (t^2)/4
% P: B: j8 H) w( P$ }7 i7 g(a - t/2)^2 = (b - t/2)^2
/ x3 P* a3 M' S6 l6 [3 ha - t/2 = b - t/2
a = b

/ H* U/ s" r  ZSo all numbers are the same, and math is pointless.

does a^2=b^2 implies a=b? why not a=-b?
