Finding two-digit numbers where the tens digit is 2 more than the units digit

To find all the two-digit numbers where the tens digit is 2 more than the units digit, we can start by examining the possible values for the units digit. Since the units digit can range from 0 to 9, we need to check each value to see if it satisfies the given condition.

Let's go through each possible value for the units digit and check if the corresponding tens digit is 2 more. We will list the numbers that meet this condition.

Numbers where the tens digit is 2 more than the units digit:

- For units digit 0: - The corresponding tens digit is 2 more, so the number is 20. - For units digit 1: - The corresponding tens digit is 2 more, so the number is 31. - For units digit 2: - The corresponding tens digit is 2 more, so the number is 42. - For units digit 3: - The corresponding tens digit is 2 more, so the number is 53. - For units digit 4: - The corresponding tens digit is 2 more, so the number is 64. - For units digit 5: - The corresponding tens digit is 2 more, so the number is 75. - For units digit 6: - The corresponding tens digit is 2 more, so the number is 86. - For units digit 7: - The corresponding tens digit is 2 more, so the number is 97. - For units digit 8: - The corresponding tens digit is 2 more, so the number is 108. However, this number is not a two-digit number, so it does not meet the given condition. - For units digit 9: - The corresponding tens digit is 2 more, so the number is 119. However, this number is not a two-digit number, so it does not meet the given condition.

Conclusion:

The two-digit numbers from 30 to 100, where the tens digit is 2 more than the units digit, are: 20, 31, 42, 53, 64, 75, 86, and 97.

Please note that the number 108 is not a two-digit number, and the number 119 is also not a two-digit number.
