Finding Numbers with the Tens Digit Two Less than the Units Digit

To find the numbers in the range from 30 to 80 where the tens digit is two less than the units digit, we can examine each number in the range and check if it meets the given condition.

Let's go through the numbers one by one:

- 30: The tens digit is 3, which is not two less than the units digit 0. So, 30 does not meet the condition.

- 31: The tens digit is 3, which is not two less than the units digit 1. So, 31 does not meet the condition.

- 32: The tens digit is 3, which is indeed two less than the units digit 2. So, 32 meets the condition.

- 33: The tens digit is 3, which is not two less than the units digit 3. So, 33 does not meet the condition.

- 34: The tens digit is 3, which is not two less than the units digit 4. So, 34 does not meet the condition.

- 35: The tens digit is 3, which is not two less than the units digit 5. So, 35 does not meet the condition.

- 36: The tens digit is 3, which is not two less than the units digit 6. So, 36 does not meet the condition.

- 37: The tens digit is 3, which is not two less than the units digit 7. So, 37 does not meet the condition.

- 38: The tens digit is 3, which is not two less than the units digit 8. So, 38 does not meet the condition.

- 39: The tens digit is 3, which is not two less than the units digit 9. So, 39 does not meet the condition.

- 40: The tens digit is 4, which is not two less than the units digit 0. So, 40 does not meet the condition.

- 41: The tens digit is 4, which is not two less than the units digit 1. So, 41 does not meet the condition.

- 42: The tens digit is 4, which is indeed two less than the units digit 2. So, 42 meets the condition.

- 43: The tens digit is 4, which is not two less than the units digit 3. So, 43 does not meet the condition.

- 44: The tens digit is 4, which is not two less than the units digit 4. So, 44 does not meet the condition.

- 45: The tens digit is 4, which is not two less than the units digit 5. So, 45 does not meet the condition.

- 46: The tens digit is 4, which is not two less than the units digit 6. So, 46 does not meet the condition.

- 47: The tens digit is 4, which is not two less than the units digit 7. So, 47 does not meet the condition.

- 48: The tens digit is 4, which is not two less than the units digit 8. So, 48 does not meet the condition.

- 49: The tens digit is 4, which is not two less than the units digit 9. So, 49 does not meet the condition.

- 50: The tens digit is 5, which is not two less than the units digit 0. So, 50 does not meet the condition.

- 51: The tens digit is 5, which is not two less than the units digit 1. So, 51 does not meet the condition.

- 52: The tens digit is 5, which is indeed two less than the units digit 2. So, 52 meets the condition.

- 53: The tens digit is 5, which is not two less than the units digit 3. So, 53 does not meet the condition.

- 54: The tens digit is 5, which is not two less than the units digit 4. So, 54 does not meet the condition.

- 55: The tens digit is 5, which is not two less than the units digit 5. So, 55 does not meet the condition.

- 56: The tens digit is 5, which is not two less than the units digit 6. So, 56 does not meet the condition.

- 57: The tens digit is 5, which is not two less than the units digit 7. So, 57 does not meet the condition.

- 58: The tens digit is 5, which is not two less than the units digit 8. So, 58 does not meet the condition.

- 59: The tens digit is 5, which is not two less than the units digit 9. So, 59 does not meet the condition.

- 60: The tens digit is 6, which is not two less than the units digit 0. So, 60 does not meet the condition.

- 61: The tens digit is 6, which is not two less than the units digit 1. So, 61 does not meet the condition.

- 62: The tens digit is 6, which is indeed two less than the units digit 2. So, 62 meets the condition.

- 63: The tens digit is 6, which is not two less than the units digit 3. So, 63 does not meet the condition.

- 64: The tens digit is 6, which is not two less than the units digit 4. So, 64 does not meet the condition.

- 65: The tens digit is 6, which is not two less than the units digit 5. So, 65 does not meet the condition.

- 66: The tens digit is 6, which is not two less than the units digit 6. So, 66 does not meet the condition.

- 67: The tens digit is 6, which is not two less than the units digit 7. So, 67 does not meet the condition.

- 68: The tens digit is 6, which is not two less than the units digit 8. So, 68 does not meet the condition.

- 69: The tens digit is 6, which is not two less than the units digit 9. So, 69 does not meet the condition.

- 70: The tens digit is 7, which is not two less than the units digit 0. So, 70 does not meet the condition.

- 71: The tens digit is 7, which is not two less than the units digit 1. So, 71 does not meet the condition.

- 72: The tens digit is 7, which is indeed two less than the units digit 2. So, 72 meets the condition.

- 73: The tens digit is 7, which is not two less than the units digit 3. So, 73 does not meet the condition.

- 74: The tens digit is 7, which is not two less than the units digit 4. So, 74 does not meet the condition.

- 75: The tens digit is 7, which is not two less than the units digit 5. So, 75 does not meet the condition.

- 76: The tens digit is 7, which is not two less than the units digit 6. So, 76 does not meet the condition.

- 77: The tens digit is 7, which is not two less than the units digit 7. So, 77 does not meet the condition.

- 78: The tens digit is 7, which is not two less than the units digit 8. So, 78 does not meet the condition.

- 79: The tens digit is 7, which is not two less than the units digit 9. So, 79 does not meet the condition.

- 80: The tens digit is 8, which is not two less than the units digit 0. So, 80 does not meet the condition.

Based on the analysis above, the numbers in the range from 30 to 80 where the tens digit is two less than the units digit are 32, 42, 52, 62, and 72.

I hope this helps! Let me know if you have any further questions.
