Worked Examples

Here are some examples of expressions you can evaluate:

Example 1: Basic Arithmetic

Expression: (5 + 3) * 2 - 8 / 4

Calculation: (5 + 3) = 8; 8 * 2 = 16; 8 / 4 = 2; 16 - 2 = 14

Result: 14

Example 2: Functions

Expression: sqrt(25) + pow(2, 3)

Calculation: sqrt(25) = 5; pow(2, 3) = 8; 5 + 8 = 13

Result: 13

Example 3: Trigonometry

Expression: sin(30) + cos(60)

Calculation: sin(30°) ≈ 0.5; cos(60°) ≈ 0.5; 0.5 + 0.5 = 1

Result: 1

Frequently Asked Questions
