Subtracting 3 Digit Numbers With Borrowing

If you’d like to tutor your kids math in subtraction, and learn the secrets to subtraction with regrouping and subtraction without borrowing, then this subtracting 3 digit numbers with borrowing might be the first step towards helping your kids to achieve a+ in math subtraction.

Each digit of a number in our number system has a different place value (ones, tens, hundreds, thousands, etc)

Always subtract within the same place value column when subtracting numbers.

Subtraction is to find the difference.

Now, let us take one simple example with three digit numbers.

Example:

Step 1

Write the problem in the columns.

Step 2

First, subtract the ones

Subtract the bottom ones place digit from the top ones place digit (7 – 9).

Here, we need to regrouping the number to make the top value larger.

Regroup 1 tens into 10 ones, so that the 7 becomes 17.

17 ones – 9 ones = 8 ones.

The 8 is placed below the line in the ones place column.

Next, subtract the tens.

The top tens place value becomes 1 after digit subtraction regrouping one tens from it.

Regroup 1 hundreds into 10 tens.

10 tens + 1 tens = 11 tens,

11 tens – 5 tens = 6 tens.

Then, subtract the hundreds

The top hundreds place value becomes 4 after digit subtraction regrouping one tens from it.

4 hundreds – 3 hundreds = 1 hundreds

You will get the answer of 168 with this math tutoring subtracting 3 digit numbers with borrowing.
