Video Solution

Solution Steps

00:00 Solve

00:03 Each time we calculate subtraction of 2 digits, and then we place

00:06 We'll start by subtracting ones from ones, and place in ones

00:09 We subtract tens from tens, and place in tens

00:12 Place 0 in the missing digits

00:16 We subtract hundreds from hundreds, and place in hundreds

00:20 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

Step 1: Write the numbers in vertical format, aligning by place values. The minuend is $677$ and the subtrahend is $22$ .
Step 2: Start subtracting from the rightmost column (units). Subtract $2$ from $7$ , which results in $5$ .
Step 3: Move to the tens column. Subtract $2$ from $7$ , which leaves $5$ .
Step 4: In the hundreds column, there's nothing to subtract from $6$ , so we retain $6$ .

The subtraction looks like this:

$\begin{aligned} 677& \\ -~ 22& \\ \underline{\phantom{7760}} \\ 655& \\ \end{aligned}$

Thus, the solution to the problem is $655$ .
