As an undergraduate I was taught to multiply two numbers with the help of log tables, using the formula a*b=10~(loga+logb) Having graduated to teach calculus to Engineers, I learned that log tables were to be replaced by slide rules. It was then that I made the fateful decision that there was no need for me to learn how to use this tedious device, as could always rely on the students to perform the necessary computations. In the course of time, slide rules were replaced by pocket calculators and personal computers, but I stuck to my original decision.
