Write a two digit odd number using 5 and 6

65 ....

Remember an odd number has to end with 1, 3, 5, 7, or 9

An even number is divisible by 2 and has to end in 0, 2, 4, 6, or 8

To write a two-digit odd number using the digits 5 and 6, you can follow these steps:

1. Identify that the number should be odd. This means that the last digit should not be a multiple of 2, which rules out using the digit 6 as the last digit.

2. Choose the first digit as 5 since it is given in the problem.

3. Select the second digit as 6 since it is the only remaining digit.

Put together, the number becomes 56, which is a two-digit odd number.
