Ascending and Descending Order for Class 4

Ascending and Descending Order

Ascending Order

Ascending order refers to arranging in increasing order, from smallest to largest or from least to greatest. This means that when arranged arranged from the lowest to highest, in a stepwise manner.

For Example,
1. Number from smallest to largest.
2. Letters in alphabetical form.
3. Objects from small to big.

Descending Order

Descending order is an arrangement where elements are listed in a sequence from largest to smallest or from highest to lowest. It is the opposite of ascending order where elements are arranged from smallest to largest or lowest to highest.

For Example,
1. Letters arranged in order from Z to A.
2. Dates sorted in most recent to oldest.
3. Higher numbers first then smallest.
4. Objects arranged from big to small.

How to Arrange in Ascending Order?

To write numbers in ascending order, you should start with the smallest number and list them in increasing order up to the largest number. Here are the general steps to follow:

1. Write down the numbers you want to arrange.
2. Compare the first two numbers. If the first number is greater than the second number, swap their positions.
3. Move to the next pair of numbers and compare them. Again, if the first number is greater than the second number, swap their positions.
4. Continue comparing and swapping adjacent numbers until you reach the end of the list.
5. Once you reach the end, the largest number will be in the last position.
6. Continue this process until all numbers are in ascending order.

How to Arrange in Descending Order?

To write numbers in descending order, you should start with the largest number and list them in decreasing order down to the smallest number. Here are the general steps to follow:

1. Start with the given list of numbers.
2. Compare the numbers in the list and identify the highest number.
3. Place the highest number at the beginning of the leftmost position.
4. Repeat steps 2 and 3 with the remaining numbers, identifying the next highest number and placing it next to the previously placed number.
5. Continue this process until all the numbers are arranged in descending order.

Ascending Order (1 to 100)

Ascending order refers to arranging numbers from the smallest to the largest. Let's take a look at how we can order the numbers from 1 to 100 in ascending order.

To begin, we start with the smallest number, which is 1. The next number in ascending order will be 2, followed by 3, and so on. Continuing this process, we can list the numbers from 1 to 100 in ascending order:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100.

Example:

Descending Order (100 to 1)

Descending order, on the other hand, involves arranging numbers from the largest to the smallest. It helps identify the maximum value in a set and allows for reverse analysis or prioritization. When sorting numbers in descending order, we start with the largest value and move towards the smallest.

100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90, 89, 88, 87, 86, 85, 84, 83, 82, 81, 80, 79, 78, 77, 76, 75, 74, 73, 72, 71, 70, 69, 68, 67, 66, 65, 64, 63, 62, 61, 60, 59, 58, 57, 56, 55, 54, 53, 52, 51, 50, 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1.

Example:

Ascending Order (101 to 1000)

Ascending order refers to arranging numbers from the smallest to the largest. Let's take a look at how we can order the numbers from 101 to 1000 in ascending order.

Example:

Descending Order (1000 to 101)

Descending order, on the other hand, involves arranging numbers from the largest to the smallest. It helps identify the maximum value in a set and allows for reverse analysis or prioritization. When sorting numbers in descending order, we start with the largest value and move towards the smallest.

Example:

Before and After

The words "before" and "after" are used to describe the position of a number in relation to another number. "Before" refers to a number that comes earlier in sequence, while "after" refers to a number that comes later.

For example: Consider the sequence of numbers: 10, 20, 30, 40, 50. In this sequence, 30 comes after 20 and before 40.

Successor and Predecessor

The terms "successor" and "predecessor" are used to describe numbers that come immediately after or before a given number, respectively.

For example, The successor of the number 7 is 8 because 8 comes immediately after 7.

For example, The predecessor of the number 15 is 14 because 14 comes immediately before 15.

More and Less Than

More Than

When we say that one number is greater or larger than another, we use the phrase "more than" to express this relationship. In mathematical terms, the symbol ">" is used to represent "more than."

For example: 5 > 3: This statement indicates that 5 is more than 3.
10 > 7: Here, 10 is more than 7.

In both cases, the symbol ">" conveys that the number on the left side of the symbol is greater or larger than the number on the right side.

Less Than

Conversely, when we say that one number is smaller or lesser than another, we use the phrase "less than." In mathematics, the symbol "<" is employed to represent "less than."

For example: 4 < 9: This statement signifies that 4 is less than 9.
20 < 25: Here, 20 is less than 25.

The symbol "<" denotes that the number on the left side of the symbol is smaller or lesser than the number on the right side.
