Video Solution

Solution Steps

00:00 Solve

00:03 Each time we consider a shortage of 2 digits, and then we'll place

00:06 5 is less than 7

00:09 Therefore we subtract 1 from the tens and add this amount to the ones

00:12 So now instead of 5 we will have 15

00:17 Subtract the ones from the ones plus ten

00:22 Place in the ones

00:26 3 is less than 6

00:31 Therefore we subtract 1 from the hundreds and add this amount to the tens

00:37 So now instead of 3 we will have 13

00:42 Subtract the tens from the tens plus ten

00:46 Place in the tens

00:50 Place 0 in the missing digits

00:54 Subtract hundreds from hundreds, and place in hundreds

00:57 And this is the solution to the question

Step-by-Step Solution

To solve this problem using vertical subtraction, follow these steps:

Step 1: Align the Numbers
Write the numbers with their digits aligned by place value:
$\begin{array}{c} 945 \\ - 67 \\ \underline{\phantom{776}} \end{array}$
Step 2: Subtract the Units Place
In the units place, we have $5 - 7$ . Since 5 is smaller than 7, we need to borrow from the tens place.
Borrowing from the tens, the 4 becomes 3, and the 5 becomes 15.
So, $15 - 7 = 8$ .
Step 3: Subtract the Tens Place
Now, subtract the tens place: $3 - 6$ . Since 3 is smaller than 6, borrow from the hundreds place.
The 9 becomes 8, and the 3 becomes 13 after borrowing.
So, $13 - 6 = 7$ .
Step 4: Subtract the Hundreds Place
Finally, subtract the hundreds place: $8 - 0 = 8$ , as there is no number in the hundreds place of 67.

Therefore, after performing the subtraction, we find that the result is $878$ .
