In the Indian (also called Hindu) system of writing numbers there are only ten symbols. For the numbers one to nine the symbols are called Anka (meaning “mark”). The zero symbol is called shunya (meaning “empty”). These ankas (digits) used for all calculations in the world are called “Hindu-Arabic” numbers.

As writing evolved the symbols are used to count and write from shunya to nine. They form the one-digit numbers or Units.

Tens and More…..
 +
 +
But how do we write ten after nine? When we have more than nine things to count, we start writing in a new column one place to the left of the anka. Thus, one place to the left of '''units or one-digit place''' we start a new column called the “tens”.
 +

 +
|+So we get the number 10,

 +
Now we know that we have more things to count, so let’s keep the ten as a group in the tens column and add more digits in the units or ones’ place.

Number 14 has 1 Ten and 4 Ones and Number 32 has ________ Tens and _______ Ones
