Clearing Variables
Variables' values are retained by Continuous Memory until you replace them or
clear them. Clearing a variable stores a zero there; a value of zero takes no
memory.
To clear a single variable:
Store zero in it: Press 0

Arithmetic with Stored Variables
Storage arithmetic and recall arithmetic allow you to do calculations with a
number stored in a variable without recalling the variable into the stack. A
calculation uses one number from the X–register and one number from the
specified variable.
Storage Arithmetic
Storage arithmetic uses
e
Ù
,
e
Ã
,
e
¸
, or
e
¯
to do
arithmetic in the variable itself and to store the result there. It uses the value in the
X–register and does not affect the stack.
New value of variable = Previous value of variable {+, –,
×
,
÷
} x.
For example, suppose you want to reduce the value in A(15) by the number in the
X–register (3, displayed). Press
e
Ã
A. Now A = 12, while 3 is still in the
display.
