Description by Calculator Inc Written by the developer, not by AppBrain. Click to read.
Its flexible expression editor lets you enter, edit, and solve calculations naturally. Move the cursor anywhere in an expression to make changes without starting over, whether you're working with basic arithmetic, fractions, percentages, or more advanced formulas. Color highlighting keeps expressions easy to read, even as they become more complex.
Switch between the simple and scientific calculator views by rotating your device. You can also enlarge the display with a single tap for easier viewing.
King Calculator works on phones and tablets of all screen sizes. Your calculation history is always available, so you can review previous results, reuse expressions, or save values to memory. Choose between two memory modes: classic Save/Clear memory, or business-calculator memory with M+, M-, and MRC buttons — the familiar style of a cash register.
The calculator also supports graphing, very large numbers, and a wide range of mathematical functions. It's completely free, with no paid features to unlock and no unnecessary permissions.
Whether you're a student, engineer, teacher, or simply need a reliable calculator every day, King Calculator has the tools you need.
