  5. The History of the Number 60 In Ancient Rome, people didn’t make a number system that we could easily understand, they used the number sixty for a lot of reasons. The numbers back then weren’t like the ones we use today, so in Ancient Rome, it was written as “LX”, the Roman numeral. They developed a system based on the number sixty so today we have sixty seconds a minute and sixty minutes an hour.

  7. Why I Chose 60 I chose the number sixty because it has many different purposes in our world and in math. All numbers are special for something, and sixty is special because of its many meanings in our world.

  8. A World Without 60 Without the number sixty, we wouldn’t have our usual time system. We might just have 86,400 seconds a day. We also wouldn’t have our usual speed system. We might be going at 1,440 km per day instead of per hour. So sixty plays an important role in daily life in both the math world and the real world.
