Numbers 0-30--Rags to Riches

I recommend you use a pencil and paper--no calculators--to get to $1,000,000. Play at least twice to get all of the questions. By the way, did I get any of the answers wrong? If so, write the problem down, the correct answer and the answer I put. I never was very good at math. I am so happy many of you played this on April 15th (martes)! ¡Buena suerte!
