Comparing and Ordering Numbers

On a number line numbers increase as we move from left to right. Each number is greater than the number of the left. It is easy to know which number is bigger or smaller.

# Comparing Numbers

- 100 is greater than 80
- 80 is equal to 80
- 80 is greater than 30
- 30 is less than 40

**Key Fact: **

Use these symbols while comparing numbers:

- = Equal to
- > Greater than
- < Less than

The cost can be compared easily with the help of place value chart.

First compare the digits at hundreds place, 3 at hundreds place is greater than 2 at hundreds place. Therefore, 350 is greater than 245. it can be written as: 350 > 245

**Compare 567 and 582**

**First compare the digits at hundreds place:**

The digit 5 at the hundreds place is same for both number.

**Compare the digits at tens place: **

Digit 8 at the tens place is greater than digit 6 at the tens place.

Therefore, 582 is greater than 567. it can be written as: 582 > 567

**Compare 892 and 895**

The digit 8 at hundreds place in both number is same.

The digit 9 at tens place in both numbers is same.

The digit 5 at ones place is greater than digit 2 at ones place. 985 > 892

# Ordering Numbers

Arrangement of numbers from the smallest to greatest is called ascending order. The blocks in this tower are arranged in ascending order.

1, 2, 3, 4, 5, 6, 7, 8, 9

Arrangement of numbers from the greatest to smallest is called descending order. The blocks in this tower are arranged in descending order.

9, 8, 7, 6, 5, 4, 3, 2, 1

Write 25, 45, 10 and 32 in ascending order.

Arrange these numbers from the smallest value to greatest value.

10, 25, 32, 45 is an ascending order.
