Functions in the ARITHMETIC menu

The ARITHMETIC menu is triggered through the keystroke combination „Þ (associated with the 1 key). With system flag 117 set to CHOOSE boxes, „Þshows the following menu:

Out of this menu list, options 5 through 9 (DIVIS, FACTORS, LGCD, PROPFRAC, SIMP2) correspond to common functions that apply to integer numbers or to polynomials. The remaining options (

1.INTEGER, 2. POLYNOMIAL, 3. MODULO, and 4. PERMUTATION) are actually sub-menus of functions that apply to specific mathematical objects. When system flag 117 is set to SOFT menus, the ARITHMETIC menu („Þ) produces:

Following, we present the help facility entries for functions FACTORS and SIMP2 in the ARITHMETIC menu(IL@HELP):

FACTORS:SIMP2:

The functions associated with the ARITHMETIC submenus: INTEGER, POLYNOMIAL, MODULO, and PERMUTATION, are presented in detail in Chapter 5 in the calculator’s user’s guide. The following sections show some applications to polynomials and fractions.
