Memory and stored variables

zL% h %{

The TI-30XS MultiView™ calculator has 7 memory

variables—x, y, z, t, a, b, and c. You can store a real number

or an expression that results in a real number to a memory

variable.

L lets you store values to variables. Press Lto store a

variable, and press z to select the variable to store. Press

< to store the value in the selected variable. If this

variable already has a value, that value is replaced by the

new one.

z accesses the menu of variables. Press this key multiple

times to choose x, y, z, t, a, b, or c. You can also use z to

recall the stored values for these variables. The name of the

variable is inserted into the current entry, but the value

assigned to the variable is used to evaluate the expression.
