The multiplication table for the whole number 15 that contains its multiples is known as the Table of 15. The table of 15 represents the repetitive addition of the number 15. For example, multiplying 15 by three is adding 15 three times (15×3 =15+15+15=45). To tackle complex multiplication problems, students are required to memorise the table of 15 in English. Learning the multiplication table of 15 has many advantages. Even with calculators easily accessible, your child needs to memorise the multiplication tables, and this article is designed to help your child with just that.
Why Should Your Child Learn The Table Of 15?
- Your little one must recognise the numbers in the multiplication tables to understand division, fractions, and ratios and spot various patterns.
- It opens the door to multi-digit multiplication and debunks the mysteries of long division and fraction simplification
- The multiplication table of 15 establishes the groundwork for algebra.
What Is Table Of 15 In Maths?
The table of 15 is slightly more complex than the single-digit multiplication tables. To understand it in simple words, the table of 15 is the repeated addition of the number 15 a certain number of times. Fifteen times two means adding 15 two times, i.e. 15 + 15 = 30. You will see that for bigger numbers, this calculation becomes too long. Hence, it is advisable to apply the multiplication operation instead. Memorising the tables is helpful for school children for solving math problems quickly using mental math. The below table represents how the table of 15 is derived.

Tips To Learn and Memorise The Multiplication Table Of 15 For Kids
The table of 15 is relatively easy to learn, however, some tips and tricks can help make this learning much simpler for the kids. There are many tips that guide your child to learn the table of 15 easily. Some of the tricks are mentioned below.
- Odd Even Number Pattern: The first trick is to look at the ten’s position of the products. In the table, for ten’s place digit, two consecutive multiples will have odd numbers followed by even numbers for the next two consecutive multiples.
Example:
15 × 1 = 15 (odd number at ten’s place)
15 × 2 = 30 (add number at ten’s place)
15 × 3 = 45 (even number at ten’s place)
15 × 4 = 60 (even number at ten’s place) - Alternate between 5 and 0: The table of 15 has a very cool underlying pattern in the ones place. This makes it very easy to memorise it. The number in the ones place in the products alternates between 5 and 0. Which means, if one product ends in 5, the next will end in 0.
The below table makes it easy to notice this pattern
15 X 1 = | 1 | 5 |
15 X 2 = | 3 | 0 |
15 X 3 = | 4 | 5 |
15 X 4 = | 6 | 0 |
15 X 5 = | 7 | 5 |
15 X 6 = | 9 | 0 |
15 X 7 = | 10 | 5 |
15 X 8 = | 12 | 0 |
15 X 9 = | 13 | 5 |
15 X 10 = | 15 | 0 |
- Triple the table of 5: The table of 5 is one of the simplest tables to learn, and children quickly master it. Make use of your knowledge of the table of 5 to learn the table of 15. To help you understand, here are some instances.
Example 1: Let’s solve 15 x 4 together.
We already know that 5 x 4 equals 20.
Now multiply the answer by three. 20 × 3 = 60, or 20+20+20.
Therefore, 15 x 4 Equals 60.

Word Problems On The Table Of 15 For Kids
Word problems are a great way to encourage kids to understand and apply multiplication tables in different situations. Here are some word problems you can use with your kids.
1. Tara wants to gift each of her 15 friends five chocolates. This means that each of her friends will receive five chocolates. How many chocolates should Tara buy?
Solution: Total number of friends = 15
Chocolates each friends get = 5
Therefore, total number of chocolates Tara should buy = 15 x 5 = 75
2. Rahul had planned to attend 5 hours of dance classes each day for 15 days. However, he ended up missing 3 hours of class on one day. How many hours of classes did Rahul complete?
Solution: Let us first break the problem down to a mathematical/numeric equation.
Total number of days = 15
Number of hours each day = 5
Total hours missed = 3
The mathematic equation will be (15 days x 5 hours) – 3 hours
Using the 15 tables, that will be 75 hours – 3 hours. Which equals 72 hours.
Therefore, Rahul attended 72 hours of dance classes in 15 days.
3. Joe had set aside 16 days to attend 4 hours of vocabulary training each day. However, he was unable to attend a 4-hour session on one single day. Calculate the number of hours Joe has spent in class.
Solution: Similar to the previous problem, let us convert the statements into a numerical equation.
Total number of days = 16
Class hours per day = 4
The number of days missed = 1. This means Joe missed one day out of the 16 days. So he attended classes for 15 days.
Therefore, the total number of hours he attended is 15 x 4 which equals to 60.
