Evaluates using standard mathematical operator precedence (PEMDAS / BODMAS):

• Parentheses: (2 + 3) × 4 = 20
• Multiplication & Division before Addition: 2 + 3 × 4 = 14
• Implicit Multiplication: 2(3) = 6, 2π = 6.28318...

Handles standalone percentages and intuitive calculator addition/subtraction markups:

• Standalone: 50% = 0.5
• Of Value: 200 × 10% = 20
• Markup: 200 + 10% = 220
• Discount: 200 − 10% = 180

Toggle between Degree (DEG) and Radian (RAD) modes with exact trigonometric simplifications:

• sin(30°) = 0.5, cos(60°) = 0.5
• tan(45°) = 1, tan(90°) = Math Error
• sin⁻¹(0.5) = 30°, cos⁻¹(0.5) = 60°
• sin(π/2 rad) = 1, cos(π rad) = −1

High-precision exponential math, logarithms, roots, and non-negative integer factorials:

• Powers: 2^10 = 1024, x², x³
• Roots: sqrt(144) = 12, cbrt(27) = 3
• Logs: log(100) = 2, ln(e) = 1
• Factorial: 5! = 120, 0! = 1
