How to use this scientific calculator
This scientific calculator handles everyday arithmetic as well as advanced operations such as sin, cos, tan, logarithms (log base-10 and ln natural), square roots, powers, and factorials. It runs entirely in your browser, so nothing is sent to a server.
Supported functions
Trigonometric functions operate in degrees. Use the xy button for arbitrary powers, n! for factorials (up to 170), and π / e to insert mathematical constants. Memory keys (M+, M−, MR, MC) let you store and recall intermediate results.
Keyboard shortcuts
Type numbers and operators directly. Press Enter to evaluate, Escape to clear, and Backspace to delete the last character. Parentheses are supported for grouping sub-expressions.
