What are some functions that are typically found on simple calculators?

A simple calculator has division, multiplication, addition and subtraction functions. It also has functions to clear entries from its memory, functions to add or subtract from memory and a recall option.

The C function on a basic calculator clears a current operation and makes room for new entries, and some calculators have a CE function to clear a single entry. The memory function on a simple calculator stores input values temporarily. The M+ function adds values to the memory, and M- subtracts from the calculator’s memory. The MR function recalls input values, while MC clears the memory. An M sign appears on the calculator’s screen when its memory is in use.
