# Mathematical Operators

You can do math equations with these operators:

|                     | Operator | Example(s)                   |
| ------------------- | -------- | ---------------------------- |
| add                 | `+`      | `x = 2 + 3;  // x is now 5`  |
| subtract            | `-`      | `y = 6 - 9;  // y is now -3` |
| multiply            | `*`      | `z = 5 * 3;  // z is now 15` |
| divide              | `/`      | `a = 9 / 3;  // a is now 3`  |
| modulus / remainder | `%`      | `b = 4 % 3;  // b is now 1`  |
| exponent            | `^`      | `c = 3^3;    // c is now 27` |

These operators, followed by an equals sign is a shortcut to adjusting the variable:

|                             | Operator | Example(s)    let's say x = 3 in all cases |
| --------------------------- | -------- | ------------------------------------------ |
| add this                    | `+=`     | `x += 3;    // x is now 6`                 |
| subtract this               | `-=`     | `x -= 9;    // x is now -6`                |
| multiply this by            | `*=`     | `x *= 3;    // x is now 9`                 |
| divide this by              | `/=`     | `x /= -1;   // x is now -3`                |
| modulus / remainder of this | `%=`     | `x %= 2;    // x is now 1`                 |
| exponent of this            | `^=`     | `x ^= 3;    // x is now 27`                |
