Solve Vertical Subtraction: 572 minus 94 Step-by-Step

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:

• Borrow 1 from the tens place (7 becomes 6), making the 2 a 12.

Now calculate:

$12 - 4 = 8$

Step 2: Subtract the tens digits:

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

• Borrow 1 from the hundreds place (5 becomes 4), making the 6 a 16.

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 $\textbf{478}$.
