Video Solution

Solution Steps

00:00 Solve

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

00:06 Subtract ones from ones, and place in ones

00:09 1 is less than 2

00:13 Therefore we'll borrow 1 from hundreds and add this amount to tens

00:17 That means now instead of 1 we'll have 11

00:22 Subtract tens from tens plus the ten

00:28 Place in tens

00:31 Place 0 in the borrowed digits

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

00:37 And this is the solution to the problem

Step-by-Step Solution

To solve the subtraction problem $819 - 27$ , we will check each digit from right to left, performing the necessary operations for subtraction:

Units place: Subtract 7 from 9. Since 9 is larger than 7, the result is 2.
Tens place: Subtract 2 from 1. Here, 1 is less than 2, so we need to borrow 1 from the hundreds place. This converts the tens place 1 into 11.
After borrowing, subtract 2 from 11, resulting in 9.
Hundreds place: Since we borrowed from 8, it becomes 7.

Finally, putting these values together gives us the result: $792$ .

Therefore, the solution to the problem is $792$ .
