    So my math teacher showed us something today that I thought was really interesting. Can anyone tell me what is wrong with this:
    1. Let a and b be equal non-zero quantities
    [IMG]
    2. Multiply through by a
    [IMG]
    3. Subtract [IMG]
    [IMG]
    4. Factor both sides
    [IMG]
    5. Divide out [IMG]
    [IMG]
    6. Observing that [IMG]
    [IMG]
    7. Combine like terms on the left
    [IMG]
    8. Divide by the non-zero b

      Number 5: divide out a-b. if a=b, then a-b=0

      Divide by zero error,
