Work through everyday expressions with a clear, offline calculator. See a live preview as you type, then open the saved result to copy it, pin it to your home screen, or continue editing the expression. EVERYDAY AND SCIENTIFIC CALCULATIONS • Add, subtract, multiply, and divide with decimals, parentheses, signs, and percent values. • Follow standard operator precedence and review readable feedback when an expression needs correction. • Use scientific functions including powers, square roots, reciprocals, absolute values, pi, e, sine, cosine, tangent, and logarithms. • Choose degrees or radians for trigonometric calculations. THREE PERCENTAGE TOOLS • Find a percentage of an amount. • Calculate the percentage change between a starting and ending value. • Work backward from a value after a percentage reduction to the value before it. Each tool displays the input relationship and formula used. KEEP YOUR WORK CLOSE Calculation history keeps the expression, result, mode, and time. Reopen an entry to copy its result, pin it to the home screen, or load its expression for editing. An unfinished expression is retained on the device, including when you leave the calculator. MAKE THE DISPLAY YOURS Select automatic significant digits or from 2 to 12 decimal places. Turn on thousands separators, a dark theme, larger expression text, or optional key feedback. Expressions are evaluated on your device. History, preferences, pinned results, and the current draft stay in local storage. No account or network connection is needed for calculations.
