Ascending order and descending order

Ascending or increasing order means arranging the numbers from the smallest to the
greatest.

example 3: Arrange the following numbers in ascending order:
32,656; 32,352; 32,682; 32,082
Solution: First, we arrange the given numbers in the tth th H T O

place value chart and then start comparing. 3 2 6 5 6 iii
32,082 is the smallest number and 32,682 is 3 2 3 = 5 < 2 ii

the greatest number. 3 2 6 8 2 iv

Also, 32,352 is smaller than 32,656.
Same Same
So, 32,082 < 32,352 < 32,656 < 32,682.

the smallest. A and B are two 5-digit

example 4: Arrange the following numbers that have the same first three
numbers in descending order: digits from the left. The number with
the greater last (units) digit is always the
4,356; 35,605; 8,78,956; 67,897 greater number. Is this statement true or

8,78,956 is the greatest number and 3 5 6 0 5 iii
4,356 is the smallest number. 8 7 < 8 9 5 6 i
Also, 67,897 is greater than 35,605. 6 7 8 9 7 ii

So, 8,78,956 > 67,897 > 35,605 > 4,356.
