        Where Do Numbers Come From?

    One plus one equals two. There are 60 seconds in one minute. Sixty minutes equals one hour. There are 24 hours in one day. One year includes 365 days. These are all basic facts that we know by heart. But have you ever stopped to think how numbers came into being and how they developed?

    It's safe to say that our society would have never developed without numbers. However, the development of numbers is still a puzzle to us. That's because when ancient people developed simple ways of counting, they didn't leave any records behind.

   It's not difficult to guess that numbers and counting began with the number "1," though ancient people probably didn't call it “one.” They likely counted by ones and recorded by carving lines on a bone.

  The earliest evidence of this is the Ishango Bone(伊尚戈骨)，which was found in 1960 in Africa. The bone is believed to be more than 20,000 years old. It has many lines on it. The lines look like what we would call "tally marks"today. Scientists think those lines show how ancient people used numbers.
