When subtracting, we start with the bottom number and subtract each digit in the top number from it.

Starting with the ones place, we can't subtract 1 from 7, so we need to regroup. This means borrowing 1 from the tens place, which becomes 2. The ones place then becomes 17 - 1 = 6.

Moving on to the tenths place, we can't subtract 1 from 0, so we need to regroup again. This means borrowing 1 from the ones place, which becomes 6. The tenths place then becomes 10 - 1 = 9.

Finally, subtracting the 2 in the tens place from the 3 gives us 1.

So the final answer is 13.6.
