Comparison of One-digit Numbers

What are the rules for the comparison of one-digit numbers?

The comparison of one-digit numbers depends on their values. The value of a number is found by adding the place values of the digits. The value of a one-digit number is its face or place value. The place value or face value of the digit of a single digit number is the same.

We know:

6 > 4

8 > 5

4 < 6

8 < 9

If we compare one-digit numbers, the number which has the greater value (face value or place value) is greater than the number which has the smaller value, as shown above.

We also know: 8 < 10 or 10 > 8

The value of 10 is greater than 8.

The value of 8 is lesser than 10.

Similarly, 7 > 3 or 3 < 7 The value of 7 is greater than 3.

The value of 3 is lesser than 7.

Arranging 1-digit numbers:

(i) Arranging the numbers 7, 5, 1, 6, 9 in ascending order:

The numbers are arranged in ascending order 1, 5, 6, 7, 9.

(ii) Arranging the numbers 4, 8, 2, 5, 6 in descending order:

The numbers are arranged in descending order 8, 6, 5, 4, 2.

Thus, any two-digit number is always greater than a one-digit number.

10 > 9 , 12 > 7 , 11 > 5 , etc.
