Abstract
When I first met Fred Brauer, he was warning a class of first-semester calculus students about the dangers of applying techniques without thinking. As an example, he wrote on the chalkboard the expression\( \frac{{\sin x}}{n} \). He then proceeded to cancel the n’s from numerator and denominator:
, leaving six.
