Example:

Suppose you made a mistake while calculating

16 19 = 304

There are three kinds of mistakes you could have made:

Reusing Numbers with LAST X

You can use to reuse a number (such as a constant) in a calculation. Remember to enter the constant second, just before executing the arithmetic operation, so that the constant is the last number in the X–register, and therefore can be saved and retrieved with .

Example:

Calculate 96.704 + 52.3947 52.3947
