All numbers are equal

Theorem: All numbers are equal.
Proof: Choose arbitrary a and b, and let t = a + b. Then

a + b = t
(a + b)(a – b) = t(a – b)
a^2 – b^2 = ta – tb
a^2 – ta = b^2 – tb
a^2 – ta + (t^2)/4 = b^2 – tb + (t^2)/4
(a – t/2)^2 = (b – t/2)^2
a – t/2 = b – t/2
a = b

So all numbers are the same, and math is pointless.
