A mathematical table that is used to define the multiplication operation for an algebraic system is known as a times table or a multiplication table. Multiplication tables are a type of table that is used to show the products of two numbers. In a basic table, one set of numbers is written as the top row, and the next set of numbers is written in the left column. Each of the products of the two corresponding numbers is written as a rectangular array of numbers.

How to Read a Multiplication Table?
Suppose we have two numbers, say 2 and 5. We want to use a multiplication table to find the product. By reading the table correctly, we can find the product. The steps to read a multiplication table are listed below.
Step 1: The first number is represented by the numbers that are listed in the leftmost column, while the second number is chosen from the topmost row.
Step 2: To reach the product, you have to start from the first number and move towards the right. Similarly, you have to move downwards starting from the second number. The product is represented by the square where the two numbers intersect.
Considering our example first, we take the number 2 in the left column and move five steps to the right. Next, we take 5 from the topmost row and move two steps to the bottom. The intersection of these gives a square consisting of the number 10. Thus, the product of 2 and 5 is 10.
Tricks to Remember during Multiplication
Before we can move on to higher-order multiplication, such as tables from 11 to 20 we have to understand the concept behind this operator. Memorizing can only take you so far. You must be well-versed with the topic before you can learn the multiplication table. Given below are a few tips to help you get started with this process.
- When you multiply a number by 1 the resultant is the number itself. Thus, 1 is also known as the multiplicative identity as irrespective of what number is chosen, when multiplied by 1, it always gives the number itself. Example, 2 * 1 = 2, 18 * 1 = 18.
- When a number is multiplied by 2, its value gets doubled. The product of a number multiplied by 2 is always an even number. For example, 13 * 2 = 36, 4 * 2 = 8.
- When a number is multiplied by 5, it will always end in 0 or 5. If the number being multiplied by 5 is odd, the product will end in 5, and if the number is even, it will end in 0. E.g., 3 * 5 = 15, 6 * 5 = 30.
- When a number is multiplied by 10, the product will be the number itself with a 0 in its unit’s place. E.g., 2 * 10 = 20, 20 * 10 = 200.
- If a digital number is multiplied by 11, the product is given by the repetition of the same number in the tens and ones place. For example, 2 * 11 = 22, 9 * 11 = 99.
Multiplication forms the basics of mathematics. Hence, it is necessary for kids to have a good understanding of the topic. They can turn to an online educational platform such as Cuemath to build a strong foundational knowledge of the topic.
The certified tutors use several resources such as math games, puzzles, online worksheets, etc., to ensure that a student masters the subject in no time. Hopefully, this article helps with your journey in learning multiplication.
