Solution Steps

00:00 Solve

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

00:07 3 is less than 7

00:13 Therefore we'll subtract 1 from the tens and add this amount to the ones

00:17 Meaning now instead of 3 we'll have 13

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

00:26 We'll place in the ones

00:31 3 is less than 5

00:35 Therefore we'll subtract 1 from the hundreds and add this amount to the tens

00:40 Meaning now instead of 3 we'll have 13

00:47 We'll subtract the tens from the tens plus ten

00:53 We'll place in the tens

00:58 Subtract hundreds from hundreds, and place in hundreds

01:01 And this is the solution to the problem

Step-by-Step Solution

To solve the subtraction problem $843 - 157$ , follow these steps:

Align the numbers vertically:
```
   843
  - 157
  ------
  
```
Start subtracting from the rightmost column (units):
- Units place: $3 - 7$ . Since 3 is less than 7, we need to borrow. Borrow 1 from the tens place, turning the 4 into a 3, and making the 3 in the units place a 13.
- After borrowing, subtract: $13 - 7 = 6$ .
Move to the tens column:
- After borrowing, we have $3 - 5$ . Borrow 1 from the hundreds place, turning the 8 into a 7, and making the tens 3 into 13.
- Subtract: $13 - 5 = 8$ .
Finally, subtract the hundreds column: $7 - 1 = 6$ .

 843
- 157
-----
  686

Therefore, the final result of the subtraction $843 - 157$ is $686$ .
