In the first version, the two factors are multiplied implicitly, with a space; in the second, explicitly, with the multiplication symbol being represented by a centered dot. (In math mode, the asterisk (*) used for explicit multiplication appears as the centered dot.)

Failure to include some form of multiplication between the factors would cause Maple to treat the expression as the evaluation of the constant function $f\left(x\right)\=36$, where $x\=3-1\=2$.

The solution is identical to the Interactive Solution, except you must press Enter to evaluate.

Note that text-mode entry is "linear" and one-dimensional. For this reason, Maple calls such notation "1-D math". Text-mode entry requires terminal punctuation, and is often harder to read than math-mode entry. Since Maple commands can be entered in either math or text form, this Study Guide will typically default to math-mode entry for any coded solution.
