Answer:

  Yes

Step-by-step explanation:

Both methods will work. You can add or subtract any number you wish from both numbers and the result will be the same.

___

<em>Comment on the approach</em>

By adding 5, Carmine makes the subtrahend have a units digit of 0, making the units digit of the answer easier to find.

By adding 2 to both numbers, Karen makes the minuend have a units digit of 0, so the units digit of the answer will be the 10's complement of 7. Depending on Karen's knowledge of arithmetic facts, this may be more work for her than Carmine's method is for Carmine.

Since all digits of the subtrahend are less than or equal to all digits of the minuend, no adjustment is needed and the subtraction can proceed directly.
