How to Write Numbers up to 4-Digits?

• 4-digit numbers are written or read according to the place values of the digits. In 4 digit numbers, the four digits correspond to the four-place values- ones, tens, hundreds, and thousands. When a number is written in standard form, each group of digits is separated by a comma which forms a period. The first period which is known as the 'one's period' is formed with the first three digits of the number. It should be noted that the placement of commas starts with 4 digit numbers. We put a comma after the hundreds place from the right because the first-period (ones) ends and the second period of thousands begins.

• When any two-digit number is multiplied by 100, the resultant number is a 4-digit number
