The addition is one of the important arithmetic operations which is mandatory for the students to learn at the primary level. Addition plays an important role in solving the problems. There are different parts in addition such as addenda, addendum, sum. The plural form of addend is called the addendum.
Addendums are seen when we add three or more numbers to find the sum. Here the students can learn deeply about addendum, properties of addition, and the question and answers related to the addition. So, we suggest the students who want to make their basics strong read the article thoroughly and solve the given problems.

What is the Meaning of Addendum?
Addendum can be defined as the numbers or terms added to the other number to form the sum.
Example: Add 2 and 3.
2 + 3 = 5
Here 2 and 3 are addendums and 3 is the sum.
Missing Addends | How to find Missing Addend in an Addition Sentence?
As the name itself tells that we have to find the missing number from the given sum and addendum (mathematical equation). You will be given an addendum and one missing term and sum. With the help of the sum and addend, you have to find the missing addend.
Let us discuss the concept with an example.
3 + _ = 9
Let the missing number be x
3 + x = 9
x = 9 – 3
x = 6
Thus the missing addend is 6.
Properties of Addition
1. Order property of addition:
We can add two numbers in any order. The sum remains the same irrespective of the order. This property is known as commutative property.
Example: 3 + 2 or 2 + 3 = 5
2. Additive property of zero:
If zero is added to a number, the sum is the number itself. The sum will not be changed. This is called the additive property of zero or additive identity.
Example: 5 + 0 = 5
See in the above example the sum of 5 and 0 is 5.
Worked Out Addendum Examples
Use the above-discussed properties of addition to add the numbers.
Example 1.
Find the sum of 4361 and 1462
Solution:
Here 4361 and 1462 are the addendums and the result is the sum of two addends.
Thus the sum of 4361 and 1462 is 5823.
Example 2.
Find the sum of 412 and 0.
Solution:
Here we use an additive property of zero to find the sum of 412 and 0.
412 + 0 = 412
Here 412 and 0 are the addendums and the result is the sum of two addends.
Thus the sum of 412 and 0 is 412.
Example 3.
John earns $15256 per month and Kiara earns $12536 per month. How much do they earn per month together?
Solution:
Given,
John earns $15256 per month and
Kiara earns $12536 per month
The total amount earned by both per month is $27,792.
Example 4.
Sandy has $2353 in her savings account and Mike has $2435 in his account. How much do they earn together?
Solution:
Given,
Sandy has $2353 in her savings account and
Mike has $2435 in his account.
Thus the amount saved by Sandy and Mike is $4788.
Example 5.
What is the sum of 2643 and 8345?
Solution:
Here 2643 and 8345 are the addendums and the result is the sum of two addends.
Thus the sum of 2643 and 8345 is 10988.
Frequently Asked Questions on Addendums

In general, an addendum is an addition required to make the sum of two or more numbers.
2. What is an Addendum equation?
In an addition equation, addendums are the numbers that are added together to give a sum.
addendum + addendum = sum
