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.
