Formula Used

The calculator evaluates expressions using standard mathematical rules. It handles:

  • Basic arithmetic: +, -, *, /
  • Parentheses for grouping: ( )
  • Exponents: ^ or **
  • Functions: sqrt(), pow(), sin(), cos(), tan(), log(), ln()

The evaluation follows the order of operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication and Division (left-to-right), Addition and Subtraction (left-to-right).

Worked Examples

Example 1: Basic Arithmetic

Expression: 3 + 5 * 2

Calculation: 5 * 2 = 10, then 3 + 10 = 13

Result: 13

Example 2: Parentheses

Expression: (3 + 5) * 2

Calculation: (3 + 5) = 8, then 8 * 2 = 16

Result: 16

Example 3: Exponents

Expression: 2^3 + 4

Calculation: 2^3 = 8, then 8 + 4 = 12

Result: 12

Example 4: Functions

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

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

Result: 13
