Math Calculators
Scientific calculator and percentage tools for everyday math, academics, and professional use.
Our math calculators cover everyday arithmetic, academic computations, and professional use cases. The scientific calculator supports trigonometry, logarithms, powers, roots, and factorial with both degree and radian modes. The percentage calculator handles all common percentage operations including increase, decrease, difference, and reverse calculation. Both tools are keyboard-friendly and work on any device.
Frequently Asked Questions
Does the scientific calculator support keyboard input?
Yes. You can type expressions directly using your keyboard. Numbers, operators (+, -, *, /), parentheses, and decimal points all work. Press Enter or = to evaluate. The display shows your full expression as you type, similar to Desmos.
What functions does the scientific calculator support?
Trigonometric (sin, cos, tan and their inverses), logarithmic (log base 10, ln natural log), exponential (e^x, 10^x), powers (x^y), roots (square root, cube root), factorial (n!), constants (pi, e), and percentage. Both degree and radian modes are supported.
How does percentage difference differ from percentage change?
Percentage change measures deviation from a reference value: (New-Old)/Old × 100. Percentage difference compares two values symmetrically: |A-B|/((A+B)/2) × 100. Use change when one value is the "before" state; use difference when comparing two independent values.
