Need help not sure why the * operator wouldn't work when adding multiplication to this code.

The operator is correct, but you still need to account for string-to-number conversion before performing math. See the "add" method for an example.

Do you have any best practice when studying a concept before moving on to the next step? I feel with some instructors the do really well to make sure you understand the concept and whats happening with your code but as you advance they go through the process as if you have been coding for years.
