Ruby Numbers Operations

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 #=> 40
```

Subtraction:

Numbers can be subtracted from one another using the - operator.
```
25 - 15 #=> 10
```

Multiplication:

Numbers can be multiplied together using the * operator.
```
10 * 5 #=> 50
```

Division:

Numbers can be divided by one another using the / operator.
```
10 / 5 #=> 2
```

Remainders:

Remainders can be found using the modulus % operator.

10 % 3 #=> 1 # because the remainder of 10/3 is 1

Exponents:

Exponents can be calculated using the ** operator.

2 ** 3 #=> 8 # because 2 to the third power, or 2 * 2 * 2 = 8
