Numbers

Diego keeps doing math in his head. Asking me if he is correct. 20+20+20=60 Today he wanted to know how many hours are in 100 days. So I showed him with a calculator how to do that figure. 24 x 100 = 2400 Then he wanted to know how many minutes are in a 1000 days. So I showed him that we first must know how many minutes are in one day so we can then multiply that number by 1000. How do we know how many minutes in one day? We have 24 hours in one day, but how many minutes are in one hour. He just wanted to know the answer though and was less interested in figuring out the problem once it got too long. 1,440,000 minutes. He thought that was exciting to see and then wanted to talk about how numbers go on forever. He wanted to go over what comes after a million and on and on. I had to look it up because after quadrillion, I couldn't remember. What comes after a quadrillion?
