Arithmetic Operators

Operators are symbols that represent a specific function within a program.

Basic operators

Addition is done using a + sign.
Subtraction is done using a - sign.
Division is done using a / sign.
Multiplication is done using a * sign.
Exponentiation is done using a ^ or ** sign.

Modulo operator

The modulo operator gives the remainder of the division of two numbers.
For example:
- 5 MOD (or %) 2 would be equal to 1. That's because 5 ÷ 2 = 2 remainder 1.
- 43 MOD 9 would be equal to 7. That's because 43 ÷ 9 = 4 remainder 7.

Integer division

The integer division operator returns the quotient (whole part) of a division.
For example:
- 5 DIV (or //) 2 would give 2.
- 43 DIV 9 would give 4.
