> 123.4*8.2^3; 68038.8112 > (23.4*43)/(43.5-(3.2*2))+(12.4*34.8); 458.6412938

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

> 13!; 6227020800 > (5^8)/(3*Pi^2)*sqrt(5); 1/2 5 390625/3 ---- 2 Pi

**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("); 29500.13725Maple also calculates finite and infinite sums and products:

> Sum((2*i+5)/(3*i^2-5),i=1..10); 10 ----- \ 2 i + 5 ) -------- / 2 ----- 3 i - 5 i = 1 > value("); 29392799449 - ----------- 48571966058 > evalf("); -.6051391746 > Product((3*Pi*i-5)/(2*i^2-Pi),i=1..10); 10 --------' ' | | 3 Pi i - 5 | | ---------- | | 2 | | 2 i - Pi i = 1 > value("); (3 Pi - 5) (6 Pi - 5) (9 Pi - 5) (12 Pi - 5) (15 Pi - 5) (18 Pi - 5) / (21 Pi - 5) (24 Pi - 5) (27 Pi - 5) (30 Pi - 5) / ((2 - Pi) (8 - Pi) / (18 - Pi) (32 - Pi) (50 - Pi) (72 - Pi) (98 - Pi) (128 - Pi) (162 - Pi) (200 - Pi)) > evalf("); -1.089588169

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:

> 5/3; 5/3 > evalf(",3); 1.67

Maple also utilizes complex numbers:

> (12+8*I)*(9+3*I)/(2+I); 276/5 + 132/5I
