Traditional arithmetic operations are supported on numeric types in LOLCODE:

BTW Addition
SUM OF x AN y

BTW Subtraction
DIFF OF x AN y

BTW Multiplication
PRODUKT OF x AN y

BTW Division
QUOSHUNT OF x AN y

Let’s start with the two most basic:

• SUM OF: Creates the sum of x and y (equivalent to x + y in most languages)
• DIFF OF: Subtracts y from x (equivalent to x - y in most languages)

If either number in an operation is a NUMBAR, the result will be too. Otherwise the result will be a NUMBR.

BTW equates to 7
SUM OF 3 AN 4

Multiple operations can be within the same statement, and will follow the traditional order as with other programming languages.

BTW equates to 5
DIFF OF SUM OF 3 AN 4 AN 2
