Calculate 677 minus 85: Vertical Subtraction Practice

Video Solution

Solution Steps

00:04 Let's begin solving the problem.

00:07 First, we'll focus on two digits at a time.

00:11 Subtract the ones place from the ones place, and write the result in the ones.

00:17 Notice that 7 is less than 8.

00:20 So, we'll borrow 1 from the hundreds and add it to the tens.

00:25 Which means, we now have 17 instead of 7.

00:33 Next, subtract the tens plus ten from the tens place.

00:39 And write that result in the tens place.

00:43 Fill any missing digits with zeroes.

00:47 Finally, subtract the hundreds from hundreds, and write the result in the hundreds.

00:53 And there you have it! That's the solution to the problem.

Step-by-Step Solution

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

Step 1: Set up the subtraction problem, aligning the numbers vertically by their place values:

$\begin{aligned} &\:6\:&7\:&&7 \\ - & \: \:&8\:&&5 \\ \underline{\phantom{777}} \end{aligned}$

$7 - 5 = 2$ . Write 2 in the units place of the answer.

We have $7 - 8$ , which requires borrowing.

Borrow 1 from the hundreds column, reducing 6 to 5, and add 10 to the 7 in the tens column, making it 17.

Now, $17 - 8 = 9$ . Write 9 in the tens place of the answer.

Now, $5 - 0 = 5$ . Write 5 in the hundreds place of the answer.

After completing all these steps, the answer to the subtraction problem is $\textbf{592}$ .

Therefore, the solution to the problem is $592$ .
