HISTORY OF COUNTING
We use counting in our day to day life. We count, the number of idlies we eat, number of glasses of water we drink. We count the money to buy a chocolate in the shop. We count the number of eggs the hen laid. We count the number of books to take to school. We count the number of kilometers to reach the city. We use counting so much that we take it for granted. We forget that the method of counting we use today has to be invented. It took many centuries for counting to reach the present form.
