stores a number and an operation for use in repetitive
calculations.
After you store the constant, you can use it in subsequent
calculations by entering a new value and pressing
N
. The
constant is cleared when you press any key other than a
numeric entry key or
N
.
Example: Multiply 3, 7, and 45 by 8.

Keystrokes for Constant Calculations
The following table shows how to set the constant for addition,
subtraction, multiplication, division, universal power, and
percent. The constant value is denoted by
