Parentheses. Do not use brackets or braces. Parentheses determine
order, but do not imply multiplication. For example, the equation P
(1-F) would be typed into the Solver as             . The ×
P
s
sign must be inserted between   and the parenthesis.
Functions and Conditional Expressions. An equation can contain any
of the functions and conditional expressions given in the table on pages
168-171. Some of these functions also have typing aids.
Math Operators ("Typing Aids"). All of the math operators are located
either on the keyboard (
, etc.). Any of these operators except
equation. (In the Solver,  is just a character.) You can call up the
MATH menu from the Solver.
Many of these operators look different in an equation: pressing
produces  , for example. You then supply a number or variable
followed by a closing parenthesis. The list of Solver functions on pages
168-171 shows the spelling of each function. Note that you supply the
number after supplying the function.
You can also type these functions letter by letter using the ALPHA menu.
However, it is faster to select math operators directly on the keyboard or
in the MATH menu. This is called a typing aid.
For instance, these two methods of placing 25! (factorial) into an
equation are equivalent. Starting after
