Online Math Calculator — Quick Cheat Sheet

• Operators: +, -, *, /, ^ (right-associative). Parentheses control order: ( ).
• Functions (1 arg): sqrt, sin, cos, tan, asin, acos, atan, ln (natural log), log (base-10), abs, floor, ceil, round, exp, fact.
• Functions (2 args): pow(a,b), min(a,b), max(a,b).
• Constants: pi ≈ 3.14159, e ≈ 2.71828.
• Angles: Trig input is in your selected angle mode (Radians or Degrees). Inverse trig returns a numeric value (radians).
• Percent: N% becomes (N/100) (e.g., 200*5% → 10).
• Limits: Expression length limited for safety; fact(n) valid for 0 ≤ n ≤ 170.
• Examples: (3+5)^2/4, sqrt(144), sin(30) (Deg), pow(2,10), fact(10).
