Easy Tricks to Learn and Remember the 18 Times Table
The Multiplication table of 18 is also called Table of 18. These contain the list of natural numbers which are multiples of 18. Learning the multiplication table of 18 will help students to improve Maths skills and they can solve Algebraic problems including LCM, HCF, and many others with speed and accuracy. This article provides a short trick to help students to learn the multiplication table easily and in a fun way.
Important Points to be Noted in Multiplication Table of 18
Multiplication is the process of repeated addition. This implies that when we add 18 to itself repeatedly, we get the multiples of 18.
For example,
3 times 18 is 54, which is the repeated addition of 18+18+18=54.
Similarly, 9 times 18 is 162, which is also equal to 18+18+18+18+18+18+18+18+18=162.
FAQs on Multiplication Table of 18
1. What is the multiplication table of 18?
The multiplication table of 18, also known as the 18 times table, is a list of the products of 18 multiplied by different whole numbers. It is essentially a sequence of repeated additions of the number 18. For example, 18 x 3 is the same as 18 + 18 + 18, which equals 54. Learning this table helps in performing calculations more quickly.
2. What are the first 10 multiples in the 18 times table?
The first ten multiples in the multiplication table of 18 are essential for basic calculations. They are:
- 18 x 1 = 18
- 18 x 2 = 36
- 18 x 3 = 54
- 18 x 4 = 72
- 18 x 5 = 90
- 18 x 6 = 108
- 18 x 7 = 126
- 18 x 8 = 144
- 18 x 9 = 162
- 18 x 10 = 180
3. Is there a simple trick to learn the 18 times table?
Yes, there's a simple pattern-based trick. First, write the first five odd numbers (1, 3, 5, 7, 9) for the tens place. Then, write the next five even numbers starting from 10 (10, 12, 14, 16, 18). For the units place, simply write the even numbers backwards from 8 (8, 6, 4, 2, 0) and then repeat this pattern. Combining these gives you the table: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180.
4. How is the table of 18 connected to the table of 2 and 9?
The table of 18 is directly related to the tables of 2 and 9 because 18 = 2 × 9. This means you can find any multiple of 18 by first multiplying the number by 9 and then doubling the result. For example, to find 18 × 5, you can calculate (9 × 5) × 2. Since 9 × 5 = 45, you just need to calculate 45 × 2, which gives you 90. This makes it easier to calculate if you already know the 9 times table.
5. How can you calculate 18 x 7 quickly using the distributive property?
You can use the distributive property of multiplication to simplify the calculation. Break 18 into simpler numbers like (10 + 8) or (20 - 2).
Using (10 + 8):
18 × 7 = (10 + 8) × 7 = (10 × 7) + (8 × 7) = 70 + 56 = 126.
Using (20 - 2):
18 × 7 = (20 - 2) × 7 = (20 × 7) - (2 × 7) = 140 - 14 = 126.
Both methods give the correct answer and can be faster than direct multiplication.
6. Why is learning the multiplication table of 18 important for students?
Learning the table of 18 is important because it strengthens a student's foundational maths skills. It enhances mental calculation speed, which is crucial for solving more complex problems in topics like division, algebra, and geometry. It also helps in real-world scenarios, such as calculating the cost of multiple items, understanding measurements, and improving overall numerical fluency as per the CBSE curriculum guidelines for 2025-26.
7. A pack of crayons has 18 different shades. How many shades would you have in total if you bought 12 packs?
This is a practical application of the 18 times table. To find the total number of shades, you need to multiply the number of shades in one pack (18) by the number of packs (12).
The calculation is: 18 × 12.
You can calculate this as 18 × (10 + 2) = (18 × 10) + (18 × 2) = 180 + 36 = 216.
So, you would have a total of 216 crayon shades.
