00:03 Each time we consider borrowing 2 digits, and then we'll place
00:06 6 is less than 8
00:09 Therefore we subtract 1 from the tens and add this amount to the ones
00:14 So now instead of 6 we will have 16
00:18 We subtract the ones from the ones plus the ten
00:21 We place in the ones
00:24 We place 0 in the borrowed digits
00:27 We subtract tens from tens, and place in the tens
00:30 And this is the solution to the question

Step-by-Step Solution

To solve this subtraction problem, we'll use the vertical subtraction method:

  • Step 1: Arrange the numbers in a column, aligning them by place value. The number 76 is our minuend, and 8 is our subtrahend.

  • Step 2: We start the subtraction from the rightmost column, the units place.

  • Step 3: Subtract 8 from 6 in the units column. Since 8 is greater than 6, we need to borrow from the tens column.

Let's break down the subtraction:

Since 8 cannot be subtracted directly from 6, we borrow 10 from the tens place.
This makes the 6 into 16 (i.e., 6+10=166 + 10 = 16), and the 7 in the tens place becomes 6.

Now subtract in the units column:
168=816 - 8 = 8

Next, move to the tens column. After borrowing to help the units column:
66 remains as it is. There is nothing to subtract in the tens column (conceptually subtracting zero), so 66 stays as 66.

As a result, the difference is:
6868

Therefore, the solution to the subtraction 76876 - 8 is 6868.

Answer

68
