<prepared>Theorem: All numbers are equal.
<prepared>Proof: Choose arbitrary a and b, and let t = a + b.
Then
<prepared>a + b = t
<prepared>(a + b)(a - b) = t(a - b)
<prepared>a^2 - b^2 = ta - tb
<prepared>a^2 - ta = b^2 - tb
<prepared>a^2 - ta + (t^2)/4 = b^2 - tb + (t^2)/4
<prepared>(a - t/2)^2 = (b - t/2)^2
<prepared>a - t/2 = b - t/2
<prepared>a = b
<prepared>So all numbers are the same, and math is pointless.
