ABACUS DEFINITION HOW TO

Three digits on the left of the group of millions form a group of billions which is split into billion, ten billions and hundred billion.The third group of the next three digits on the left of the group of thousands form the group of millions which is split into millions, ten million and hundred million.The second group of the next three digits on the left of the group of ones form the group of thousands which is further split into thousands, ten thousand and hundred thousand.The first three digits on the extreme right form a group of ones which in turn split into hundreds, tens and units. The ones, in turn, split up into hundreds, tens and units.The groups are called ones, thousands, millions and billions.We start from the extreme right digit of the number to form the groups.The following are the features of the International System of Numeration – In this system, a number is split up into groups or periods.

The place value chart of numbers is followed by most of the countries around the world. A place-value chart is a way to make sure digits are in the correct places. Let us understand how the place value chart is defined.
