The new simple formula objectDM5-4.tex#Formulas provides a
way to enter a mathematical expression together with a Maple operation. What
appears on your screen is the result of the operation. For example, if you
enter
4a + 7b - 2a + b
in the Formula area and choose Simplify
from the Maple menu, on your screen you'll see 2a + 6b. The expression is
not displayed on the screen.
