 Pro Let a = b. Then a^2 = ab. Subtract b^2 from both sides. Then a^2-b^2=ab-b^2. Use difference of squares. (a+b)(a-b)=b(a-b) Divide both sides by (a-b). Then a+b=b. Now let a=1, then b=1. Substitute a=1 and b=1 into a+b=b. Thus 2=1.Report this Argument Con Jackie-Chan That formula is totally wrong. You jump from a+b=b. The only number possible for A is 0, but you don't explain enough. Then at the bottom, 2+1=1, then the next line is, "thus 2=1" if you count your fingers, 2 plus 1 is 3 fingers. I make it easy, you have 2 apples. I have one apple. They are same size, shape, etc. Who has more, me or you? It isn't equal.Report this Argument

Righty10294's argument is right but with a bad argument. Look at Miserlou's comment. You cannot divide by zero.

wats funny is that in higher up math like calculus the formulas you are given will come out so 2=1 or or somthing like that it possible to prove but quite simply you went about it the wrong way

You fall apart at (a+b)(a-b)=b(a-b). You can't divide by (a-b), because if a=b then (a-b)=0 and you can't have 0 in the denominator.

Ha, this is really funny.

I voted Pro in every one of these except for the debate where Con actually showed what was mathemtically wrong.

Nice try con, but if his math is correct you could say a and b are anynumber you want so long as they are equal.

your math is off my friend

i said (or ment) a=2 and b=1, then 1=2 is 3

a+b+b.
You said that a+b is 3. I disagree.
