The TI-30XS 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.
[sto right arrow]
(store) lets you store values to variables. Press
[sto right
arrow]
to store a variable, and press
[Xabcyzt]
to select the variable to store.
Press
enter
to store the value in the selected variable. If this variable already has
a value, that value is replaced by the new one.
[Xabcyzt]
(memory variable) accesses the menu of variables. Press this key
multiple times to choose
x, y, z, t, a, b,
or
c
. You can also use
[Xabcyzt]
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.
