International Placevalue Chart
In International placevalue system, there are three periods
namely Ones, thousands and millions for the nine places from right to left.
Ones period is made up of three placevalues. Ones, tens, and hundreds. The
next period thousands is made up of one, ten and hundredthousands. The next
period thousands is made up of one, ten and hundredthousands. The pattern
continues and the next three places make millions period. So, writing a number
in international placevalue system, we insert commas after every three digits
from the right.
To read the number, we read all the digits together in the same period followed by the name of the period from left to right.
