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

00:07 2 is less than 4

00:12 Therefore we subtract 1 from the tens and add this amount to the ones

00:16 So now instead of 2 we will have 12

00:20 We subtract the ones from the ones plus ten

00:23 We place in the ones

00:26 6 is less than 9

00:29 Therefore we subtract 1 from the hundreds and add this amount to the tens

00:36 So now instead of 6 we will have 16

00:39 We subtract the tens from the tens plus ten

00:44 We place in the tens

00:47 We place 0 in the missing digits

00:50 Subtract hundreds from hundreds, and place in hundreds

00:53 And this is the solution to the question

Step-by-Step Solution

Let's solve the problem using vertical subtraction. We have:

$\begin{array}{c} & 5 & 7 & 2 \\ - & & 9 & 4 \\ \hline \end{array}$

Step 1: Subtract the rightmost digits (units):

We have $2 - 4$ , which is not possible without borrowing. So, we need to regroup:

Now calculate:

$12 - 4 = 8$

Step 2: Subtract the tens digits:

We are left with $6 - 9$ , which again requires us to regroup:

Now calculate:

$16 - 9 = 7$

Step 3: Finally, subtract the hundreds digits:

We now have $4 - 0$ , since there is no digit above in the subtrahend:

$4 - 0 = 4$

Putting it all together, the subtraction yields:

$\begin{array}{c} & \phantom{1} 5 & 7 & 2 \\ - & \phantom{1} & 9 & 4 \\ \hline & \phantom{1} 4 & 7 & 8 \\ \end{array}$

Therefore, the answer to the problem is $\textbf{478}$ .
