In Ruby you can perform all standard math operations on numbers, including: addition `+`

, subtraction `-`

, multiplication `*`

, division `/`

, find remainders `%`

, and work with exponents `**`

.

## Addition:

- Numbers can be added together using the
`+`

operator.

```
15 + 25
# returns:
40
```

## Subtraction:

- Numbers can be subtracted from one another using the
`-`

operator.

```
25 - 15
# returns:
10
```

## Multiplication:

- Numbers can be multiplied together using the
`*`

operator.

```
10 * 5
# returns:
50
```

## Division:

- Numbers can be divided by one another using the
`/`

operator.

```
10 / 5
# returns:
2
```

## Remainders:

- Remainders can be found using the modulus
`%`

operator.

```
10 % 3
# returns:
1 # because the remainder of 10/3 is 1
```

## Exponents:

- Exponents can be calculated using the
`**`

operator.

```
2 ** 3
# returns:
8 # because 2 to the third power, or 2 * 2 * 2 = 8
```
