Video Solution

Solution Steps

00:00 Solve

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

00:06 2 is less than 5

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

00:14 Meaning now instead of 2 we'll have 12

00:20 Subtract the ones from the ones plus ten

00:23 Place in the ones

00:26 Subtract tens from tens, and place in tens

00:30 Place 0 in the missing digits

00:34 Subtract hundreds from hundreds, and place in hundreds

00:38 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

Step 1: Set up the numbers for vertical subtraction.
Step 2: Perform subtraction starting from the rightmost digit (units place).
Step 3: Apply regrouping whenever the top digit is smaller than the digit below.

Now, let's work through each step:
Step 1: Write the numbers in vertical format aligning by place value:

$\begin{array}{c} 482 \\ - 65 \\ \hline \end{array}$

Step 2: Subtract the digits in the units place: $\quad 2 - 5$ . Since 2 is smaller than 5, we need to regroup.

Regrouping: Borrow 10 from the tens place, making 2 become 12. The 8 in the tens place decreases by 1 to 7.

$\begin{array}{c} 4 &\cancel{8}7 \, &12 \\ -\ \ &6&5 \\ \hline \end{array}$

Subtract in the units place: $12 - 5 = 7$ .

Step 3: Move to the tens place: Now subtract $7 - 6 = 1$ .

Finally, subtract in the hundreds place: As there’s no digit to subtract from 4, it remains $4$ .

Therefore, after performing the subtraction, the result is:

$\begin{array}{c} 417 \\ \end{array}$

Thus, the solution to the problem is $417$ , which corresponds to choice 2.

Therefore, the solution to the problem is $417$ .
