Solution Steps

00:00 Solve

00:03 Each time we consider subtraction of 2 digits, and then we substitute

00:06 5 is less than 7

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

00:17 So now instead of 5 we will have 15

00:26 Subtract the ones from the ones plus ten

00:31 Place in the ones

00:34 Place 0 in the missing digits

00:37 Subtract tens from tens, and place in the tens

00:40 And this is the solution to the question

Step-by-Step Solution

To solve this problem, follow these steps:

Step 1: Write the numbers vertically with 35 on top and 7 underneath. Align them by their rightmost digits.
Step 2: Start subtracting the rightmost digit (units place). Subtract 7 from 5.
Step 3: Since 5 is smaller than 7, we need to regroup. We take 1 ten from the tens place, turning 35 into 25 and 15.
Step 4: Subtract 7 from 15 in the units place, which gives us 8.
Step 5: Move to the tens place. After regrouping, 25 has a digit of 2 in the tens place. Subtract 0 from 2, which remains 2.

The result of the subtraction is $28$ .

Therefore, the correct answer is 28.
