Arithmetic

You can do basic arithmetic operations like addition, subtraction, multiplication, division, exponentation within code.

local sum = 1 + 5

The above code will put the result of 1 + 5 and put that into the sum variable. If you print the variable, 6 should be displayed in the output.

The following operations are supported:

• + Addition
• - Subtraction
• * Multiplication
• / Division
• ^ Exponentation

These symbols are called Arithmetic Operators.

You can put anything around these operators, such as variables.

local side = 5
local area = side ^ 2

You can also chain multiple operators.

local a = 5
local b = 5
local c = 2
 
print(a + b * c)

This will print 15, not 20 as the order of operations is applied, meaning that multiplication is done before addition.

You can also use paranthesis.

print((a + b) * c)

Modulo Operation

The modulo (also known as "modulus" or "mod") is the remainder after dividing one number by another.

local remainder = 5 % 2
print(remainder)

This will print the remainder of 5 divided by 2, which is 1. You can use the modulo operator to check if a number is even or odd. If x % 2 is 0 then x is even, otherwise it is odd.
