What Can Appear in an Equation
Long Equations. There is no limit on the length of an equation (or the number of variables it has) if there is enough memory to store it. An equation longer than one display line (22 characters) moves to the left and adds an ellipsis (...).
To view a long equation, move the cursor using the arrow keys on the
looks like
when it is stored. Press to view successive portions of the equation:
Spaces. You can use as many spaces as you like between variables, operators, and numbers.
Names of Variables. A variable’s name can be up to 10 characters long, but cannot contain the characters + - x ⎟ ^ ( ) < > = : space
The first three to five characters (depending on their widths) become the variable’s menu label. Therefore, make sure no two variables in the same equation have the same first three to five characters.
Do not use AND, NOT, OR, XOR, or PI as variable names because they will be interpreted as functions.
Numbers (Constants). Do not put commas or other characters in numbers. For instance, type for ten thousand (not ).
