You cannot remove an entered operation symbol from the input field. If you enter two operator symbols in sequence, the latter one replaces the former symbol. Otherwise you can use backspace to remove the last value character in the input field when editing a calculation.

Using calculator memory

It is possible to store one number value at a time in the memory of the calculator and then recall it, and add or substract a value to/from this value in the memory. When any number value besides zero (0) is saved in the memory, the letter M appears at the upper left side of the input field. If zero (0) is saved, it means the same as clearing the memory.
