Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right. Ascending order is also sometimes named as increasing order. For example, a set of natural numbers are in ascending order, such as 1 < 2 < 3 < 4 < 5 < 6 < 7 < 8… and so on. The less than symbol (<), is used to denote the increasing order. The inverse method of increasing order is descending order, where the numbers are arranged in decreasing order of values.

What is Ascending Order?
In Mathematics, ascending order is the process of arranging the numbers in increasing order, i.e., from smallest value to largest value. That means the numbers are arranged from left to right in increasing order. A reallife example of ascending order is an arrangement of English alphabets from A to Z.
The word ‘ascending’ means going up. Hence, in the case of Mathematics, if the numbers are going up, then they are arranged in ascending order.
The other terms used for ascending order are:
 Lowest value to highest value
 Bottom value to Top value
Note: It is not necessary that the numbers are available in a pattern, to be arranged in ascending order.
Ascending order symbol
Ascending order is denoted by the less than symbol ‘<‘. For example,
1 < 2 < 3 < 4 < 5 < 6 < 7 < 8 < 9
The above numbers are arranged in ascending order from 1 to 9.
The symbol represents that the succeeding number is greater than the preceding number in the arrangement.
The sign of ascending order represents numbers from lowest to highest, which is opposite to the concept of descending Order, where numbers are arranged from largest to smallest.
Examples of Ascending Order
Some of the examples of numbers arranged in ascending order are given below:
 1 < 2 < 3
 10 < 11 < 12 < 13
 43 < 55 < 78 < 98 < 101
 100 < 1000 < 10000
 10 < 9 < 8 < 7
Ascending Order on Number Line
The concept of ascending order is been introduced in primary classes for students of Class 1. With the help of the number line, students can easily understand the arrangement of numbers in increasing order.
In the above number lines numbers from 6 to 6 are arranged in ascending order. It states that numbers on the left side of 0 are smaller than the numbers on the right side of 0. As we go from left to right on the number line the value of numbers increases.
How to Arrange Numbers in Ascending Order?
To arrange the numbers in ascending order, first, we need to compare the values and then order them in ascending order.
We can arrange here different numbers such as:
 Integers
 Negative numbers
 Fractions
 Decimals
Arranging Integers in Ascending Order
As we know integers are numbers that can be negative, positive or zero. But they are not fractions. Let us learn how to arrange positive integers in ascending order.
 Firstly compare the number of digits in each number
 The number with lesser digits is the smallest number
 The number with the largest digits is the largest number
 If the number of digits is the same, then compare the leftmost digits of the numbers
 Compare the numbers in the same manner and arrange them all from smallest to largest.
Example: 2 < 4 < 12 < 23 < 451 < 541 
Negative Numbers in Ascending Order
Arranging negative numbers can be a little challenging for the students at the beginning. But once they have understood the logic, it will be very easy for them to arrange the numbers in ascending order.
If a bigger number is having a negative sign, then it becomes the smallest value. For example, 3 is greater than 2, but 3 is smaller than 2.
Similarly, a twodigit negative number is smaller than a singledigit negative number.
43 < 8
50 < 25 < 10 < 1 
Fractions in Ascending order
There are two methods involved in finding the ascending order of the fractional numbers. Both the method will give the same solution
Method 1:
 Step 1: For a given series of fractions, first convert it into decimal numbers.
 Step 2: Find the increasing order of the decimal numbers.
 Step 3: Finally, replace the decimal values with the respective fractional numbers.
Method 2 :
 Step 1: Find the L.C.M of the denominators.
 Step 2: Divide the L.C.M value by the denominator of the fraction.
 Step 3: Multiply both the numerator and denominator of the fraction with the resultant value of step 2.
 Step 4: As a result of step 2 and step 3, compare the like fractions.
 Step 5: Since the denominators are the same, compare the numerator values of like fractions.
 Step 6: Finally, arrange the fractions in increasing order with their respective fractions given in the problem.
Decimals in Ascending Order
To arrange the list of decimal numbers, first, check which decimal has the least whole number part. Now arrange the decimals with increasing order of whole number part.
If the whole number part is the same for two or more decimals, then arrange the decimals according to the decimal part after th decimal point, in ascending order.
Example: 1.2 < 2.3 < 3.5 < 3.6 < 3.8 < 4.3
Ascending order of Alphabets
Same as numbers you can also arrange alphabets in ascending order and descending orders. For example : a < b < c < d < e < f < g < h < i < j < k < l < m < n < o < p < q < r < s < t < u < v < w < x < y < z (For small alphabets).
You can reverse the order of the alphabets in the case of descending order.
Ascending Order and Descending Order
Descending order is the contradiction of ascending order. That means it is the opposite process of writing the numbers in increasing order. Therefore, it can be mentioned as a decreasing order. In the case of descending order, for a given set of numbers, the highest valued number is written first, and the lowest valued number is written at last. It is denoted by the symbol ‘>’.
Ascending Order  Descending Order 
Numbers are arranged in increasing order  Numbers are arranged in decreasing order 
Smallest to largest  Largest to smallest 
It is represented by less than symbol: ‘<’  It is represented by greater than symbol: ‘>’ 
Example: 3<6<7<9<10  Example: 10>9>7>6>3

Solved Problems on Ascending Order
Question 1: Arrange the numbers 34, 10, 6, 4, 45, 25 in ascending order.
Solution: The increasing order of the numbers are 4, 6, 10, 25, 34 and 45
Question 2: Write these numbers in ascending order: 8, 10, 92, 1, 27.
Solution: The following is the increasing order of the given numbers:
1 < 8 < 10 < 27 < 92
Question 2: Arrange the following numbers in increasing order.
6^{3} , 7^{2} , 4^{2} , 2^{6} ,3^{4} and 10^{2}
Solution: Given , 6^{3} , 7^{2} , 4^{2} , 2^{6} ,3^{4} and 10^{2}
6^{3} = 6 x 6 x 6 = 216
7^{2}= 7 x 7 =49
4^{2 }= 4 x 4 = 16
2^{6} =2 x 2 x 2 x 2 x 2 x 2 = 64
3^{4} = 3 x 3 x 3 x 3 = 81
10^{2} = 10 x 10 = 100
Therefore, the increasing order of the numbers are 16, 49, 64, 81, 100 and 216 and will be represented as : 4^{2} < 7^{2} < 2^{6} < 3^{4 }< 10^{2} < 6^{3}

Solution:
Given series: 8/6, 2/3, 10/12 and 9/6.
Step 1: Converting fractions into decimals
8/6 = 1.33
2/3 = 0.67
10/12 = 0.83
9/6 = 1.5
Step 2: Arranging the increasing order of the decimal values
0.67 < 0.83 < 1.33 < 1.5
Step 3 : Replacing the decimal values with fraction values
2/3 < 10/12 < 8/6 < 9/6
Therefore, the increasing order of the given fractions is 2/3, 10/12, 8/6 and 9/6.

Frequently Asked Questions on Ascending Order
What is the ascending order and descending order?
How can we arrange the numbers in increasing order?
By arranging them in ascending order, we have to figure the smallest value first, which is 9.
9
Now the number greater than 9 here is 11. Therefore,
9<11
It indicates that 11 is greater than 9. In the same way, we can arrange all the numbers as;
9<11<15<23<43<55
