Hello friends, welcome to Learn More!

I'm Vibha, today I will share a brand new subtraction method, this will you calculate any subtraction mentally in just 7 seconds.

Let's see how the traditional method works.

You can't subtract 9 from 8, so we note down 18 here and will write 6 above 7. You can't subtract 9 from 6, so we note down 16 here.

Now, we don't want to do this complicated method.

Mentally borrow method causes lots of error, we will get the answer wrong. So it's better to avoid this method.

But this new method will work perfectly fine and will help you get the answer quickly and accurately. Let's start!

Here is the first example, subtract 539 from 827. As you can't subtract 9 from 7, that means it's a miss-match number.

Just number for a miss-match number, you need to put minus sign (-) and the difference of that numbers. here, the difference is 2.

You can't subtract 3 from 2, that means it's a miss-match number. The difference is 1 and we will put minus sign (-) as well.

We can easily subtract 5 from 8, so we will put plus sign (+) and the difference of that numbers. Here, the difference is 3.

Now, consider the answer in 1's, 10's, and 100's. We will write +300, -10, and -2.

we will get the answer once we will complete calculation based on the sign. We will get the answer 288.

It's super easy and very fast, just understand this method properly.

Let's take another example, subtract 047 from 600. You can't subtract 7 from 0, that means it's a miss-match number.

For this type of situation where 0 is on the upper side then you need to write the below number as it is and put minus sign (-).

As you can't subtract 4 from 0, that means we will put minus sign (-) and number 4. You can easily subtract 0 from 6, so we will put plus sign (+) and 6.

Now, consider the answer in 1's, 10's, and 100's. We will write +600, -40, and -7.

Let's do the calculation and we will get the answer 553.

Let's do the 3rd example mentally, subtract 8006 from 7529. First, we will consider this 1's, 10's, 100's, and 1000's.

We will write directly -1000, +500, +20, +3, after the calculation we will get the answer -477.
