3x18 = 24? 3x18 = 54.

I figured you might be rushing. :)

I'd also add that you added your 24 and 36 to get 60. Then you added 100, not 90, to that to get 160. In fact, it's 90+60 which is 150.

Keep practicing, you'll get there! You were doing great until you made those two mistakes. You've got the general idea of it.

Yeah, you always know you are getting really good at math when your arithmetic goes to hell!
