  1. 32-bit up to 4 billion - if-and-only-if all the numbers being calculated were positive. Otherwise you had a 4 billion spread across half positive and half negative with 2 billion each.This time expansion was fun!

  2. Perhaps before your time, but multiplication and division were handled another way. You looked up the two numbers on the slide rule to get the logarithms and added them then looked up that number on a different part of the slide rule for the anti-logarithm. For division you subtracted instead of adding. In addition, in many schools the logarithms were printed on the desks (along with sin, cos, tan). We got to be very fast with a slide rule.
