What is Ordering?
Ordering means arranging in a sequence.
To order numbers, the value of each digit is worked.
There are two ways of ordering:
How to order numbers?
When ordering numbers, always start by comparing the digits at the highest place value.
For example, to order - 291, 829, 576, we’ll compare the value of digits at the highest place value i.e. hundreds.
The ascending order i.e., smallest to biggest is 291, 576, 829.
The descending order i.e., biggest to smallest is 829, 576, 291.
What if the digits in a column are the same?
If the digits in a column are the same, we’ll look at the next column.
Here, we’ll start by looking at the hundreds. As 817 has 8 hundreds which are the highest, it is the biggest number.
Now, 563 and 566 have the same hundreds, we’ll look at the tens.
As they have the same tens, we’ll look at the ones.
So, the descending order is 817, 566, 563.
