I didn't see that the check for the multiplication symbol was commented out for this test suite until I checked your solution...
Sorry about that. I added a statement that that function restriction is lifted in the problem description. Still, I'm impressed that you were able to solve it without using that function.
No worries. Multiplication without the * symbol is easy enough. There's a reason the final variable in my first solution is named "cheat" though; I had no idea how to accomplish the final check otherwise.
Well, I'll take that as a compliment, then, because your problems are clever and often stump me.
