The TI-30X Pro MathPrint™ calculator has 8 memory variables—
x
,
y
,
z
,
t
,
a
,
b
,
c
, and
d
.
You can store the following to a memory variable:
•
real or complex numbers
•

•
calculations from various applications such as Distributions
•
data editor cell values (stored from the edit line)
Features of the calculator that use variables will use the values that you store.
L
lets you store values to variables. 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
is a multi-tap key that cycles through the variable names
x
,
y
,
z
,
t
,
a
,
b
,
c
, and
d
.
You can also use
z
to recall the stored values for these variables. The name of the
variable is entered in the current entry, but the value assigned to the variable is used to
evaluate the expression. To enter two or more variables in succession, press
"
after
each.
% h
recalls the values of variables. Press
