Functions

Simple Calculator supports a wide range of operations beyond simple number crunching. Users can perform percentage-based calculations for discounts and taxes, apply trigonometric functions such as sine, cosine, and tangent for geometry-related tasks, and use exponential functions for scientific work. It also includes memory buttons (M+, M−, MR, MC) so users can store intermediate results while solving multi-step problems. A built-in history panel lets you revisit earlier equations, making it easier to track your workflow and avoid re-entering data.

How to Use

Click the button "Check All Versions" below to download and install it. Once installed, launch the app and choose between basic or advanced mode depending on your needs. Enter numbers using the on-screen keypad, tap operation symbols for calculations, and view results instantly on the display. To store a value, press the memory button; to recall it later, simply tap the recall option. If you make an error, use the backspace key to delete the last entry or clear the entire input with the AC button. For repeated calculations, scroll through the history log to reuse previous equations without retyping them.
