Solution Steps

00:00 Solve

00:03 Each time consider borrowing 2 digits, and then we'll place

00:06 7 is less than 8

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

00:15 So now instead of 7 we'll have 17

00:19 Subtract the ones from the ones plus the ten

00:22 Place in the ones column

00:25 Place 0 in the borrowed digits

00:29 Subtract tens from tens, and place in tens column

00:32 Subtract hundreds from hundreds, and place in hundreds column

00:36 And this is the solution to the problem

Step-by-Step Solution

To solve this problem, we need to perform the vertical subtraction of $8$ from $227$ . Let's break down the steps:

Step 1: Write the subtraction problem in column form: Place $227$ above $8$ , aligning the digits on the right.
Step 2: Perform the subtraction starting from the rightmost digit (the units place).
- The units digit of the minuend is $7$ and the subtrahend is $8$ . Since $7 < 8$ , we need to borrow:
- Borrow 1 from the tens place (turning the $2$ into $1$ ), making it $17$ instead of $7$ .
- $17 - 8 = 9$ . Write the $9$ below the line in the units place.
Step 3: Move to the tens digit:
- After borrowing, the digit left in the tens place of the minuend is $1$ .
- Subtract: $1 - 0 = 1$ (since there is no subtrahend digit in the tens place).
Step 4: Move to the hundreds digit:
- The hundreds digit is $2$ and since we haven't changed it, it remains $2$ .
- Since there are no digits to subtract from in the hundreds place, the digit remains $2$ .

Now, combining the results from each digit, the final answer becomes $219$ .

Therefore, the solution to the problem is $219$ .
