Common maths arithmetic operators
There are a six arithmetic operators you should cwertainly be aware of, although their are others.

* multiplication.  For example, 4 * 3 = 12

/ division.  For example, 16 / 4 = 4

MOD is the remainder. For example:

      • 10 MOD 6 = 4
      • 21 MOD 4 = 1
      • 8 MOD 2 = 0.

It is the remainder after you have divided the second number into the first.

DIV is integer divison. for example:

      • 10 DIV 2 = 5
      • 14 DIV 3 = 4
      • 20 DIV 7 = 2

This is the number of times the second number will completely go into the first number.
