Numbers Entered in Program Lines 
Before starting program entry, set the base mode. The current setting for the base 
mode determines the base of the numbers that are entered into program lines. The 
display of these numbers changes when you change the base mode. 
Program line numbers always appear in base 10. 
An annunciator tells you which base is the current setting. Compare the program 
lines below in the left and right columns. All non–decimal numbers are 
right–justified in the calculator's display. Notice how the number 13 appears as 
"D" in Hexadecimal mode.

Polynomial Expressions and Horner's Method 
Some expressions, such as polynomials, use the same variable several times for 
their solution. For example, the expression 
Ax
4
Bx
3
Cx
2
Dx + E
uses the variable x four different times. A program to calculate such an expression 
using ALG operations could repeatedly recall a stored copy of x from a variable. 
Example: 
Write a program using ALG operations for 5x
4
 + 2x
3
, then evaluate it for x = 7.
