Forming 2-Digit Numbers

We can form numbers using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

Let’s learn to form 2-digit numbers using the given digits.

• 2-digit numbers formed using the digits 5 and 9 are 59 and 95.

• Similarly, we can form 2-digit numbers when more than two digits are
given.

2-digit numbers formed using the digits 3, 4 and 8 are:

34, 43, 48, 84, 38 and 83

• If one of the digits is 0, place it at the ones place as 0 in the beginning has
no value.

2-digit numbers formed using the digits 2, 5 and 0 are:
25, 20, 52 and 50

19. Write the 2-digit numbers formed using the given digits.
