Use * for multiplication, / for division, and ^ for exponentiation. You can also use functions such as sqrt() exp(), ln(), cos() and sin(). Also, ch(n, k) will evaluate "n choose k". For example, ch(4,2) = 6
fac(n) is n! - so for example, fac(4) = 24.
Finally, you can sum a series with the sigma command.
For example, sigma[2, 6,1/k^2] evaluates the sum from k=2 to k=6 of the expression 1/k^2.
Note that []'s are used in sigma and not parentheses. The summation variable must be k.
