Addition means to calculate the total amount of something. In three digit addition the numbers that are being added are three digit numbers. It is very similar to double digit addition and if we know double digit addition then this will not be difficult to understand.

See the fact file below for more information on the three digit addition or alternatively, you can download our 28-page Three Digit Addition 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:

  • Addition means to calculate the total amount or sum of numbers combined.
    Example: 2 + 1 = 3
  • Addition of two digit numbers: 21 + 11 = 32
  • Addition of three digit numbers = 100 + 213 = 313
  • Addition can be with or without carry.
  • When we add zero to a number, the number remains as it is.
    Example: 400 + 0 = 400
  • Addition is one of the most basic operation that will help us understand future operations.
  • Addition is very useful and it helps us solve everyday problems.

What is addition?

  • Addition means to calculate the total amount of something. Mathematics has many important operations. Out of the four basic operations addition is the first one.
  • Addition has significance in our lives because of its common usage. We use it every single day at our homes, offices, schools etc.
  • When we add numbers we calculate their total amount. This total amount is also known as sum of numbers. We start with learning single digit addition and then increase the digits. The symbol for addition is “+”.

Single digit addition

  • Following are examples of single digit addition. In these examples we add two single digit numbers.

1 + 3 = 4
5 + 2 = 7
3 + 6 = 9

  • The results of these examples are also single digit numbers.
  • Adding or subtracting zero from a number does not change its value.

1 + 0 = 1
0 + 8 = 8

Two digit addition

  • After learning single digit addition we move to double or two digit addition. In this type of addition the numbers that we are adding are two digit numbers. Here we can have two cases. Either a carry term will be present or it will not be present. Adding zero to a two digit number will not affect the number.
  • Here is an example of double digit addition without carry:

25 + 10 = 35

Three digit addition

  • In three digit addition the numbers that are being added are three digit numbers. Adding zero to a three digit number will not affect the number. Three digit addition can also be with or without carry. It is very similar to double digit addition and if we know double digit addition then this will not be difficult to understand.
  • Here the concept will be elaborated with the help of examples. First we will start with the case where there is no carry.

211 + 234

  • We will arrange these numbers vertically so that all the digits at ones place are in a vertical line, all the digits at tens place are in a vertical line and all the digits at hundreds place are in a vertical line.

  • After arranging vertically we will add digits at ones place, tens place and hundreds place as shown:

1 + 4 = 5
1 + 3 = 4
2 + 2 = 4

So, 211 + 234 = 445

  • Now we will discuss a case where we have to use carry digits. Suppose we have to add the following two numbers:

452 + 119

  • In this case again we will arrange the terms so that the numbers are vertically on top of one another as shown:

  • In this example adding the digits at ones place will generate a carry. So we will solve the addition problem as shown below:

So, 452 + 119 = 571

Example:

  • If Mona bought 100 apples and 250 oranges from the farmers market, how many fruits does she have in total?

apples = 100
oranges = 250
total fruits = apples+oranges
total fruits = 100 + 250

  • We arrange the numbers vertically to solve the problem:

  • We will add the digits at ones, tens and hundreds place to get:

0 + 0 = 0
0 + 5 = 5
1 + 2 = 3

total fruits = 350

Example:

  • Eric bough 118 cartons of milk and 114 cartons of eggs to distribute it to the needy. How many total number of cartons does Eric have?

cartons of milk = 118
cartons of eggs = 114
total cartons = cartons of milk + cartons of eggs
total cartons = 118 + 114

  • We arrange the numbers vertically to solve them as shown:

  • In this example when we add digits at ones, tens and hundreds place we see that a carry is generated. Addition with carry is not difficult at all. Once we know the concept we can add even larger numbers.

So, total cartons = 232
