Subtraction is a very basic operation in mathematics. It is not just used when sitting in our maths class but it is also used at our homes and at our workplaces. Just like two digit subtraction we can have two cases in three digit subtraction.

See the fact file below for more information on the three digit subtraction or alternatively, you can download our 28-page Three Digit Subtraction worksheet pack to utilise within the classroom or home environment. This worksheet is broken down by Beginner, intermediate and advanced meaning you can choose the complexity level for your student.

Key Facts & Information

Summary:

  • Subtraction simply means to take a number away from another number.
    Example: 15 – 10 = 5
  • When we subtract zero from a single, double or three digit number the number remains unaffected.
    Example: 205 – 0 = 205
  • Just like two digit subtraction we can have two cases in three digit subtraction. Either we borrow or we do not borrow. This depends upon the problem.
  • Subtraction is a very basic operation in mathematics. It helps us learn and understand other important operations.
  • It is used in everyday tasks.

What is subtraction?

  • Just like addition subtraction is also a very fundamental operation in mathematics. We use subtraction all the time. It is not just used when sitting in our maths class but it is also used at our homes and at our workplaces. If we want to simply define subtraction we can say that when we take one amount away from an amount then this process is called subtraction. We subtract smaller numbers from larger numbers. The symbol for subtraction is “-”. We start with single digit subtraction then move to two digit subtraction and from there we move to three digit subtraction. Here is an overview of single and double digit subtraction.

Single digit subtraction

  • In single digit subtraction the numbers that are being subtracted are single digit numbers. Here are a few examples of single digit subtraction:

3 -1 = 2
9 – 5 = 4
6 – 0 = 6

  • Subtracting zero from a number means that the number will remain the same.

Double digit subtraction

  • In double digit subtraction we are dealing with two digit numbers. We can have two cases in double digit subtraction. Either we borrow or we do not borrow. It depends on the type of problem. Here is an example of subtraction with no borrow.

44 – 21

  • Here we will arrange the numbers vertically so that all digits at ones and tens place are aligned.

  • Once they are aligned we will perform the following subtractions:

4 – 1 = 3
4 – 2 = 2

So, 44 – 21 = 23

Three digit subtraction

  • In three digit subtraction we subtract three digit numbers. It is just like two digit subtraction. In this we can either have subtraction with borrow or without borrow. It depend upon the type of question we are solving. First we will discuss the case where there is no borrow. Consider the following numbers:

444 – 214

  • We will arrange them vertically so that all the digits at ones , tens and hundreds place are aligned as shown below:

  • Once they are aligned we perform the following subtractions:

4 – 4 = 0
4 – 1 = 3
4 – 2 = 2

So, 444 – 214 = 230

  • Now we will discuss the case where we have to borrow. Let’s consider the following two numbers:

381 – 116

  • We will again arrange these numbers vertically. Once they are arranged so that numbers at ones, tens and hundreds place are on top of one another then we perform subtraction:

  • We have to borrow a digit because 1 is smaller than 6. We cannot subtract 6 from 1 therefore we borrow a digit from tens place. The following subtractions take place at ones, tens and hundreds place:

11 – 6 = 5
7 – 1 = 6
3 – 1 = 2

So, 381 – 116 = 265

  • In some cases we have to borrow twice. We use the same procedure for those cases as well.

Example:

  • There were 665 science books in the library. Some of the science books were donated to another school. If 224 books were donated, how many books are left?

total books = 665
donated books = 224

  • Now the books left in the library can be found by subtracting the donated books from the total books:

books left = total books – donated books
books left = 665 – 224

  • We arrange these numbers vertically so that ones , tens and hundreds place are on top of each other:

  • After arranging them vertically we perform the following subtractions at ones, tens and hundreds place:

5 – 4 = 1
6 – 2 = 4
6 – 2 = 4

So, 665 – 224 = 441

  • 441 books are left in the library.

Example:

  • There were 752 students in the old campus. 225 students were shifted to a new campus. How many students are left in the old campus?

old campus students = 752
shifted students = 225

  • To find the students left in the old campus we subtract the students shifted to new campus from the total students in the old campus:

students left = old campus students – shifted students
students left = 752 – 225

  • We arrange these digits vertically so that ones , tens and hundreds place are on top of each other:

  • After arranging them vertically we perform the following subtractions at ones, tens and hundreds place:

12 – 5 = 7
4 – 2 = 2
7 – 2 = 5

  • We notice that in this case we borrowed a digit from tens place.

So, 752 – 225 = 527
