If a command ends in a colon, Maple hides the output of the command. Ordinarily, this is fine. However, if you want to insert a sequence of commands at a particular spot in a worksheet, you may find yourself having to create a number of new input prompts. You can use quotation marks to refer to the previous output. As an example, the following commands produce the output 41 .
Maple tries to give exact answers.
If you ever want a numeric answer, you can apply the command evalf to a calculation. Maple distinguishes between expressions and functions. Functions are defined using a different syntax than expressions. The two are entirely different strings of text. Many Maple commands operate only on expressions, or only on functions.
