Math Processor is capable of processing ordinary arithmatic expressions as well as more advanced commands consisting of different functions and variables.

Let's have a look at our first simple session with MP:

>> 2+3*4

>> 14.0000

>> (2+3)*4

>> 20.0000

An interesting point to note is that you can change the priority of operations by using parenthises. When parenthises are not used in the expression **2+3*4**, the multiplication takes precedence. However, in the second command the order of calculations is overridden by providing parenthises around the first term: 2+3.

Let's try to do a more interesting thing this time

{

a = vectorin (0, 0.05, 2*pi);:

b = sin(a);:

c = b*1.5;:

d = b*2;:

plot (a, b, a, c, a,d):

}

After executing the above block of code, you should see three sine curves in a new window opened by MP.
