The TI-30XPlus MultiView™ calculator has 8 memory
variables—x, y, z, t, a, b, c, andd. You can store a real
or complex number or an expression result to a
memory variable.
Features of the calculator that use variables (such as
the solvers) will use the values that you store.
L lets you store values to variables. Press L to
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 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 inserted into 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.
