In 6 Maths Chapter 1 Knowing Our Numbers, we will study about comparing the number (smaller or greater), selecting the smallest or greatest numbers, order of numbers (ascending or descending).

Ascending order: Ascending order means arrangement from the smallest to the greatest.

Descending order: Descending order means arrangement from the greatest to the smallest.

Concepts of Place values, face values and questions based on the numbers as follow:

Starting from the greatest 6-digit number, write the previous five numbers in descending order.

Starting from the smallest 8-digit number, write the next five numbers in ascending order.

The Indian System of Numeration: In our Indian System of Numeration, Commas are used to mark thousands, lakhs and crores. We use ones, tens, hundreds, thousands and then lakhs and crores. The first comma comes after hundreds place and marks thousands. The second comma comes two digits later. It comes after ten thousands place and marks lakh. The third comma comes after another two digits. It comes after ten lakh place and marks crore.
