- Addition: +, e.g., 2 + 3 = 5
- Subtraction: -, e.g., 5 - 2 = 3
- Multiplication: × or -, e.g., 3 × 4 = 12
- Division: ÷ or /, e.g., 12 ÷ 3 = 4
- Exponentiation: ^, e.g., 2^3 = 8
- Parentheses: (), e.g., (2 + 3) × 4 = 20

Order of Operations (PEMDAS): Parentheses, Exponents, Multiplication/Division, Addition/Subtraction (performed left to right).

Examples:

- 10 + 5 - 3: 10 + 5 = 15, 15 - 3 = 12
- 2 × 3 + 4: 2 × 3 = 6, 6 + 4 = 10
- (2 + 3) × 4: 2 + 3 = 5, 5 × 4 = 20
- 2^3 - 1: 2^3 = 8, 8 - 1 = 7
- 10 ÷ 2 + 3: 10 ÷ 2 = 5, 5 + 3 = 8
