So, how and why does Mod tell if a number is even or odd? Well, any integer dividing evenly by 2 will have a remainder of 0. Odd numbers will have a remainder...
Mod = remainder of an integer division (i.e. 9 Mod 2 = 1)
| + | addition (i.e. 2 + 3 = 5) |
| - | subtraction (i.e. 7 - 3 = 4) |
| * | multiplication (i.e. 3 * 7 = 21) |
| / | division (remember that the result may not be of the Integer type - i.e. 9 / 2 = 4.5) |
| \ | integer division (always returns an integer result - i.e. 9 \ 2 = 4) |
| Mod | remainder of an integer division (i.e. 9 Mod 2 = 1) |
| ^ | power (i.e. 2 ^ 3 = 8) |
