Subtraction

In this lesson, we will look at some examples of the subtraction of whole numbers.

 

 

Subtraction Without Borrowing

We do not need to borrow if the first digit is large enough to subtract the second digit.

Example : 97 – 33 = 64

 

 

Subtraction With Borrowing

We need to borrow if the first digit is smaller than the second digit.

 

Example : 91 – 77 = 14

The result of subtraction is called the difference of the numbers. In the above example, 13 is the difference of 91 and 77.

 

Example : 1,000 – 576 – 48 = 376

 

 

The following video gives more examples of subtraction with borrowing.
