Solve: 310 - 110.352 Using Vertical Subtraction Method

In order to avoid confusion whilst solving the exercise, add three zeros to the number 310 as follows:

$310.000\\-110.352\\$

Proceed to solve the exercise in the correct order:

Let's subtract the thousands after the decimal point:

$0-2=$

Given that we cannot subtract, we will instead borrow ten from the tens digit of the whole number before the decimal point, due to the fact that the other numbers are also zeros.

The tens digit of the whole number before the decimal point will become 0, and the hundreds digit of the whole number before the decimal point will become 10

We'll borrow ten from the hundreds digit before the decimal point and it will change from 10 to 9, and now the tenths digit after the decimal point will become 10

We'll borrow ten from the tenths digit after the decimal point and it will change from 10 to 9, and now the hundredths digit after the decimal point will become 10

We'll borrow ten from the hundredths digit after the decimal point and it will change from 10 to 9, and now the thousandths digit after the decimal point will become 10

Now that we know how to solve the exercise, let's subtract the thousands after the decimal point:

$10-2=8$

Let's subtract the hundreds after the decimal point:

$9-5=4$

Let's subtract the tenths after the decimal point:

$9-3=6$

Finally, let's subtract the whole numbers before the decimal point accordingly:

$9-0=9$

$0-1=$

Given that we cannot subtract, we will instead borrow ten from the ones digit of the whole number and we should obtain the following:

$10-1=9$

Remember that we borrowed ten from the ones digit, as shown below:

$3-1-1=1$

And we obtain:

$310.000\\-110.352\\199.648$
