Since a=b, a-b=0 and zero cannot be divided by the Left-hand side and the Right-hand side of an equation, no can zero can be cancelled on both the sides. This may result in absurd conclusions like 10=100, 500=1000 etc.

Only when the the two sides of an equation are divided by a non-zero entity, can they be equal.]]>
