Learn math and have fun – Bubbly Primes Review

What a great idea! Why didn't they have this when I was in elementary school? I wanted to brush up on my basic math skills. So I downloaded this to try it. It is great. It taught me to memorize my prime numbers and was fun enough to keep my interest. Yesterday, I was driving down the 880 freeway and instantly thought: 880 = 2*2*2*2*5*11. Yes! I got it.
