Solve Vertical Subtraction: 274 minus 86 Step-by-Step

Video Solution

Solution Steps

00:04 Let's solve this math problem step by step.

00:07 We begin by looking at borrowing two digits.

00:11 The number 4 is less than 6.

00:15 So, we need to borrow. We subtract 1 from the tens place and add it to the ones.

00:21 Now, instead of 4, we have 14.

00:28 Subtract the ones from 14, and place the result in the ones column.

00:33 Notice that 6 is less than 8.

00:37 We need to borrow again, subtract 1 from the hundreds, and add it to the tens.

00:43 Now, we have 16 instead of 6.

00:46 Subtract the tens from 16, and place the result in the tens column.

00:54 Then place a zero in any missing digits.

00:57 Lastly, subtract the hundreds and place the answer in the hundreds column.

01:02 And there you have it, the problem is solved!

Step-by-Step Solution

To solve this subtraction problem, we will follow these steps:

Step 1: Line up the numbers vertically to align the digits by place value.
Step 2: Start from the units column, note $4 - 6$ requires borrowing from the tens place.
- Since 4 is smaller than 6, we borrow 1 from the next higher place value. The tens digit (7) becomes 6, and the units digit becomes $14$ .
Step 3: Subtract in the units column: $14 - 6 = 8$ .
Step 4: Move to the tens column, subtract $6 - 8$ . Since we borrowed from the hundreds place, it simplifies to $16 - 8 = 8$ .
Step 5: The hundreds digit in the minuend is $2$ , reduced by 1 due to previous borrowing, makes the effective hundreds $1$ .
Step 6: Finally, in the hundreds column, subtract $1 - 0 = 1$ .

Let's summarize the steps calculations as follows:

$\begin{aligned} 274& \\ - \ 86& \\ \overline{\phantom{2}188} \\ \end{aligned}$

Upon completion, the final result is $188$ .
