About the Basic Calculator

A simple, easy-to-use calculator with memory keys, square root, percentages and a history of your calculations.

How to use the Basic Calculator

  1. Click or tap the number and operator buttons to build your calculation.
  2. Use √, x², 1/x and % for quick operations, and +/− to change the sign.
  3. Store values with MS or M+, recall them with MR and clear memory with MC.
  4. Use ⌫ to delete the last digit and AC to clear everything. Past results appear under Calculation History.

Tips

  • M+ adds the displayed value to memory and M− subtracts it, which is handy for running totals.
  • For powers, trigonometry and logarithms, use the Scientific Calculator.

Frequently asked questions

What does the MR button do?
It recalls the number stored in memory and shows it on the display.
