Answer multiplication problems to get money, after each number (3's, 4's, 6's, 7's, 8's) pay 3 dollars to keep the laser. If you lose the laser, an asteroid will destroy Earth. You start with 10 money. Also, you only have 10 seconds for each problem,if it is longer, I will warn you, take two money away, and start the time over. Have a fun time!
I wanted to make a fun way of learning multiplication, for my sister.
