Addition Table 1 to 15
Addition is a basic math operation used to calculate the sum of numbers. An addition table shows numbers in rows and columns, forming a pattern that helps us quickly find the sum of two numbers without having to calculate them by hand.
What is Addition Table 1 to 15
An addition table from 1 to 15 shows the sums of all pairs of numbers between 1 and 15. These numbers are shown in a grid where the first row and the first column have all numbers from 1 to 15.
Each cell shows the sum of the numbers from its row and the numbers from its column. This table helps students solve problems more easily.

The addition table is also known as the addition chart. Let us take a look at the addition chart for the sum of numbers between 1 and 15 given below.
Tips and Tricks for Addition Tables 1 to 15
As the numbers get larger, addition tables become harder to memorize. Here are a few tips and tricks to help learn them.
- Use the commutative property. Since addition is commutative, you only need to learn half the table because the other half is just its mirror.
- Learn doubles such as 7 + 7. They act as quick mental math shortcuts.
- Notice the diagonal pattern.
- Each number is 2 greater than the one before it, which helps in building the table quickly.
Common Mistakes and How to Avoid Them in Addition Tables 1 to 15
Sometimes, even visual tools like addition tables can be confusing. Here’s a list of errors students might make while working with these tables, along with ways to avoid them.
Mistake 1
Mixing up rows or columns
Always double-check the row and column before writing the sum. For example, 10 + 5, if you mistakenly use row 11 and column 5, you might write 15 instead of the correct answer, 10 + 5 = 15.
Mistake 2
Forgetting the commutative property
Always remember that a + b = b + a, so you don’t need to calculate both separately. For example, if you already know 12 + 3 = 15, you don’t need to solve 3 + 12 again.
Mistake 3
Confusing doubles and near doubles
Always learn doubles first (like 8 + 8 = 16), then use them to solve near doubles. For example, if you know 9 + 9 = 18, then you can easily solve 9 + 10 = 19.
Mistake 4
Skipping numbers in sequence
Always remember to follow the pattern. Each number in a row or column increases by 1. For example, in row for 7, the sums should go 8, 9, 10, 11… If you skip a number, the sequence will be incorrect.
Mistake 5
Memorizing without practice
Practice regularly with objects or flashcards to strengthen the understanding. For example, instead of just memorizing that 13 + 4 = 17, try imagining 13 apples and then adding 4 more to see the result.
Solved Examples on Addition Table 1 to 15
Problem 1
Find the sum of 9 + 6 using the table
15
Explanation
In the addition table, look for 9 in the top row and 6 in the left column. The cell where they meet gives the result 15.
Problem 2
What is 11 + 4?
15
Explanation
To find 11 + 4 in the addition table, locate 11 in the top row and 4 in the left column. The cell where they meet shows the answer as 15.
Problem 3
If 14 is added to 14, what is their sum according to the table?
28
Explanation
In the addition table, find 14 in the top row and 14 in the side column; where they meet, the answer is 28. This is a double, so adding 14 and 14 always gives 28.
Problem 4
What do we get when we add 15 and 5?
20
Explanation
In the addition table, find 15 in the top row and 5 in the side column; where they meet, the answer is 20. Adding 5 to 15 also gives 20.
Problem 5
Use the table to find 12 + 3
15
Explanation
In the addition table, look at 12 in the top row and 3 in the side column; where they meet, the answer is 15. You can also count three steps after 12 (13, 14, 15) to get 15.
