Expression Templates

Expression templates give you an easy way to enter math expressions in standard mathematical notation. When you insert a template, it appears on the entry line with small blocks at positions where you can enter elements. A cursor shows which element you can enter.

Position the cursor on each element, and type a value or expression for the element.

Fraction template Note: See also / (divide), page 212.

Example:

/p keys

Exponent template

Example:

Note: Type the first value, press l, and

then type the exponent. To return the cursor

to the baseline, press right arrow (?).

Note: See also ^ (power), page 213.

Square root template

Note: See also () (square root), page 223.

Example:

l key /q keys

Nth root template Note: See also root(), page 154.

Example:

/l keys
