Double 10 is 2 x 10 which is 20, so now, just add all these numbers… 10 10 20 45 15. The answer is 100.
This is actually the answer to the old riddle… What is 10, 10, double 10, 45, 15?
Others say it’s the fastest way to count to 100!
Still others say the fastest way to count to 100 is…
99 cows and a bobtailed bull!

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!
