CALCULATOR KEYS AND FUNCTIONS

CalculatorLibrary currently has 87 calculators online, and each calculator can have dozens of keys. Add to that all the real world calculators available and you'll soon realize there are a lot of calculator keys out there with a lot of different functions. What do all of these keys do?

Some calculator keys are obvious, but some are more obscure or specialized. Obviously we can't cover every possible key and function here, however this guide will try to explain the main ones you're likely to encounter.

Some calculators use "secondary" or "shift" keys, sometimes color coded such as f, g or 2nd that allow multiple functions to be allocated to each key. In other words, pressing a secondary key first changes the function processed by another key.

In addition to these widely used keys, there are often special keys that allow you to access unique functions for that particular calculator. Check the user manual or online instructions for more information about these unique or special function keys available on your chosen calculator.

Here at CalculatorLibrary, you can click or touch the keys on your screen to perform calculations using our free online calculators, however many calculators also have keyboard shortcuts that allow you to use your computer or device keyboard to enter many of the values. Check the "Notes" section near the bottom of each calculator to see these options.
