In this section, we will be discussing number arithmetics. Number arithmetics can be used to create a math expression for your script. Here are the tables.

### ARITHMETIC

| Operator |    Operation   |
| :------: | :------------: |
|     /    |    Division    |
|    \*    | Multiplication |
|     +    |    Addition    |
|     -    |   Subtraction  |
|     %    |     Modulus    |
|     ^    |    Exponent    |

### COMPOUNDS ASSIGNMENT

| Operator | Operation      |
| -------- | -------------- |
| +=       | Addition       |
| -=       | Subtraction    |
| \*=      | Multiplication |
| /=       | Division       |
| %=       | Modulus        |
| ^=       | Exponentiation |

### **HOW ARITHMETIC WORKS**

**Division** - Division can be used to divide numbers.\
**Multiplication** - Multiplication can be used to multiply numbers.\
**Addition** - Addition can be used to add numbers.\
**Subtraction** - Subtraction can be used to subtract numbers.\
**Modulus** - Modulo can be used to find a reminder of a division.\
**Exponent** - Exponent takes two value called base and power.The base is mulitplied with itself for power times (ex: 5^2 = 5\*5)

### BASIC USAGE

This is how you should use arithmetic and compound assignments in a script.

#### DIVISION

```lua
local Number = 2
print(Number / 2) -- 1
Number = 4
Number /= 2
print(Number) -- 2
```

#### MULTIPLICATION

```lua
local Number = 2
print(Number * 2) -- 4
Number = 4
Number *= 2
print(Number) -- 8
```

#### ADDITION

```lua
local Number = 2
print(Number + 2) -- 4
Number = 4
Number += 2
print(Number) -- 6
```

#### SUBTRACTION

```lua
local Number = 2
print(Number - 2) -- 0
Number = 4
Number -= 2
print(Number) -- 2
```

#### MODULUS

```lua
local Number = 2
print(Number % 2) -- 0
Number = 4
Number %= 3
print(Number) -- 1
```

#### EXPONENT

```lua
local Number = 2
print(Number ^ 2) -- 4
Number = 4
Number ^= 3
print(Number) -- 48
```
