Hit "Evaluate" to see the results of each computation. You can edit the contents of a cell to do your own computations.
(There are also some Linear Algebra cells.)
You can do arithmetic.
You can multiply out.
You can factor.
You can (try to) solve equations, and use show() to ask for pretty formatting.
Here is an example of plotting. You can use sin(x), cos(x), log(x), exp(x), etc. Powers are done as x^2 or x**2. Use parentheses and * for multiplication. The second argument is the interval to plot over.
Here is one that is discontinuous at 0. Try zooming in by changing the interval to (-0.1,0.1) etc.
