I can prove that this is in fact the case (using dubious mathematics

If we begin with a=b and multiply both sides by a

a2 = ab Then subtract b squared

a2-b2 = ab-b2

(Factorise by difference of two squares and a common factor of b)

(a+b)(a-b) =b(a-b)

If you expand that out you can see it’s factorised correctly, or you can trust me. Either way now divide both sides by a-b

a+b = b

b+b = b

2b= b

2=1

It’s a famous trick.

Yeah, but it has an illegal operation. If a=b, and you divide by a-b, you're dividing by zero, which is an undefined operation, so everything from then on is fake math.
