Addition: Adds two numbers together. Example: 20 + 30 = 50

Subtraction: Subtracts the second number from the first. Example: 80 - 25 = 55

Multiplication: Multiplies two numbers. Example: 7 * 8 = 56

Division: Divides one number by another. Example: 56 / 7 = 8

Modulus: Finds the remainder when dividing one number by another. Example: 28 % 6 = 4

Pre-increment: Increases the number by 1 before using it. Example: ++12 = 13

Post-increment: Uses the number first, then increases it by 1. Example: 15++ = 15, now it is: 16

Pre-decrement: Decreases the number by 1 before using it. Example: --9 = 8

Post-decrement: Uses the number first, then decreases it by 1. Example: 16-- = 16, now it is: 15
