Integer arithmetic and operators

In this module

• Compute with //, %, ** and /, using precedence and parentheses to control the order Python evaluates a longer expression.
• Predict what // and % give with negative numbers, and recognize the ZeroDivisionError that dividing by zero raises.
• Shorten repeated updates to a variable with augmented assignment.
• Use abs, min, max, divmod and pow instead of writing that arithmetic by hand.
