Session 1

If you do not remember how to start Quantum, review Running Quantum once more, then come back here.  Start Quantum and reproduce what you see in the Quantum session below.



Integer's, Float's, and Ratio's are Number's.  Symbol's, Number's, and String's are Object's.  Expressions (fn x_1 ...  x_n) are Expr's.  Expr's evaluate as Quantum function calls.  Function calls can return Expr's.  For example, (* 1.7 (^ x 2) (^ y 2)) is an Expr.  Expressions [x_1 ...  x_n] and
#[[...  ...]] are Arrays's.  You can use the special function Setq to assign values to Symbol's.
