Challenge: Let's play with the *args pattern.

Create a function named multiply that takes any number of arguments. Return the product (multiplied value) of all of the supplied arguments. The type of argument shouldn't matter.

Slices might come in handy for this one.

EDIT: ( I found help on this thread )

Regarding your issue: total = n * item, total is being replaced each time, and the previous value for total is being lost. Ex: multiply(1,2,3,4) total = n*item plays out as below: total = 1 * 2 (total = 2) total = 1 * 3 (total = 3) total = 1 *4 (total = 4)

Also be careful making total equal to 0. 0 times any other number is 0.
