Adding with Zero

Here we will learn math adding with zero tables up to 25. The facts on zero addition tables can help us to learn how to add the numbers with 0. These are designed to help your child to improve their mental addition skills.

Adding with zero will help your child to learn how to solve addition sums where one of the addend is 0 and the other addend is any of the number. And when you add zero to a number, the number stays the same. 0 + 0 = 0


The adding with zero (0) tables up to 25 are shown in the following table.

0 Addition Table

When we add two numbers together and interchange the same addend we find the same sum in all. 

Now we will interchange the addend and see if their sum changes in the following related addition table:

Zero Addition Table

From the above addition table we came to know that, any number adding with zero does not change the number. Children should understand and memorize the basic addition facts for 0 tables. The ideas and tricks can help the child to calculate the numbers to find the related addition facts.


Examples based on adding with zero (0):

1. Which is the related addition fact for 5 + 0 = 5?

(a) 0 + 9 = 9

(b) 0 + 5 = 5

(c) 0 + 0 = 0

(d) 1 + 0 = 1

Solution:

We know that we can add numbers in either order. We will get the same sum. Related addition facts use the same numbers.

The related addition fact for 5 + 0 = 5 is 0 + 5 = 5.

Notice how the addend 5 and the addend 0 interchanged their places but still their sum remains same.


2. Which is the related addition fact for 0 + 21 = 21?

(a) 21 + 0 = 21

(b) 15 + 0 = 15

(c) 0 + 0 = 0

(d) 12 + 0 = 12

Solution:

We know that we can add numbers in either order. We will get the same sum. Related addition facts use the same numbers.

The related addition fact for 0 + 21 = 21 is 21 + 0 = 21.

Notice how the addend 21 and the addend 0 interchanged their places but still their sum remains same.
