Mathcad
Mathcad, by Mathsoft, is a fantastic tool for learning and using math on your computer.
It's unique feature is that the math looks just like what you would write on paper,
except it is "live." So if you change the value of a variable at the top of your page,
it automatically calculates the resulting changes in the rest of your document. It does
its calculations from left to right, top to bottom, following the order of operations
of mathematics of course. One thing that you will see right
away that is a little different is that when you define a variable in Mathcad, say x=5, it usually appears as
x:=5. The extra colon is Mathcad's way of telling the program that you want to initially
define something. Later on if you type x= Mathcad would automatically show you that
x=5.
