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
