In August 2010. I am visiting the Airforce Museum in Dayton, Ohio. My nearly 86 year-old Dad is with me. My Dad spots a rocket displaying 45 15 on its side. He immediately rattles off "10 10 double 10 45 15!" "What's that mean, Dad?" "The fastest way to count to 100!", he said. I was baffled and still am!
10 is not.
3m + 15 = 45 3m = 30 m = 10
10:23 am 60 - 45 = 15 38 - 15 = 23
11:15
