Storing a value in a variable

Accessing the display history

You can save an answer in a variable and use the variable in later calculations. There are 27 variables available for storing real values. These are A to Z and θ. See Chapter 11, “Variables and memory management” for more information on variables. For example:

1.Perform a calculation.

45>￿@8 >[8@3 >(17(5@

2.Store the result in the A variable.

672a?a>$/3+$@A >(17(5@

3.Perform another calculation using the A variable. 95>￿@2>;@>$/3+$@A
