The STory of our Number S
Tens of thousands of years ago, people started counting. They wanted to
keep records of their things. So they made marks on the walls of caves
and on the barks of trees.
Over time, they kept records of their things by making groups of 5, 10,
20, and 60.
Thousands of years ago, the ancient Indians created a method for
writing any number, however large, using only ten symbols: 0, 1, 2, 3,
4, 5, 6, 7, 8, 9. It was one of the most ingenious and creative inventions
in human history. It made possible the invention of TVs, computers,
mobile phones, and more. This method of writing numbers is now used
everywhere in every country in the world.
A very important part of this invention was the introduction and use of
the symbol “0” to mean “nothing”. It is the number 0 that really made
this system of writing numerals work!
Over the next few months, we will learn how to write all numbers, however
large, using just these ten symbols.
