Arithmetic Operators

Add, subtract, multiply, divide.

Doing Math in Lua

Lua gives you a full set of arithmetic operators to combine numbers. They work much like the math you already know.

In this lesson you will use them to add, subtract, multiply, divide, and more.

print(2 + 3)
print(10 - 4)

The + operator adds two numbers and - subtracts them.

You can mix integers and floats freely. If either side is a float, the result becomes a float.

local total = 5 + 2.5
print(total)
