Solution Steps

00:00 Solve
00:03 Each time we calculate subtraction of 2 digits, and then we place
00:06 7 is less than 9
00:09 Therefore we subtract 1 from tens, and add this sum to ones
00:16 Meaning now instead of 7 we'll have 17
00:21 Subtract ones from ones plus ten
00:25 Place in ones
00:28 Place 0 in the missing digits
00:31 Subtract tens from tens, and place in tens
00:34 And this is the solution to the question

Step-by-Step Solution

To solve this subtraction problem, we'll use the following steps:

  • Step 1: Subtract the ones place.

  • Step 2: Employ borrowing if necessary.

  • Step 3: Subtract the tens place after borrowing.

Now, let's apply these steps:

Step 1: Subtract the ones place.
In the ones place, we have 797 - 9. Since 77 is smaller than 99, we need to borrow.

Step 2: Borrow from the tens place.
Borrow 11 from the tens place, turning the 6767 into 55 tens and 1717 in the ones place. Now, perform 179=817 - 9 = 8.

Step 3: Subtract the tens place after borrowing.
Now that we've borrowed, we have 55 in the tens place. Subtract 00 (there's nothing to subtract, effectively). So, the tens remain 55.

The final result after the subtraction is:
Therefore, the answer is 5858.
