Found this online, see if you can find the error.

Assume this to be true.
1. a = b

Multiply both sides by a.
2. ab = a^2

Subtract b^2 from both sides.
3. ab - b^2 = a^2 - b^2

Factor both sides.
4. b(a - b) = (a + b)(a - b)

Divide both sides by a - b.
5. b = a + b

Given a = b, so replace a with b.
6. b = 2b

Divide both sides by b.
7. 1 = 2

To give u guys a hint...the algebraic evaluation of the problem is correct, but there is a logical error in one of the steps....

that bit about subtraction looks odd.. wouldn't ab - a2 equal 0 given a = b. so 0 = 0 and then again in step 4 u get 0 = 0. and you can't divide 0 by another 0 now can you?

Trig got it!!

It's Step 4, since a = b, you would be dividing by 0. Now you can go get your buzz. =)

Yea Fezz but a and b don't necessarily have to be 0. The point is just that if a = b, for any value, a - b is going to equal 0. The key error is division by 0 in step 4.
