458.6412938Maple also recognizes many special operators such as factorial, square roots, least common divisor, etc. For example:
> 13!;

Note that Maple kept answer in the form
of an expression, i.e., it does not
round off the answer. Maple will allow this
expression to carry over as is
so that rounding errors do not plague the
user. If one wants to see the final answer as
a decimal floating point, the
evalf command can be used. Also
note that the quotation mark (") is used
to represent the last expression computed:
> evalf(");

Maple also calculates finite and infinite sums
and products:
> Sum((2*i+5)/(3*i^2-5),i=1..10);

Notice the above gets a little messy on an ASCII screen. It looks better on an X-Window session
One can round off the value to any number of decimal places desired:
