Multiplication and tables are maybe the most useful of all the tools you’ll learn in mathematics! Multiplication can help you solve problems fast, and using multiplication tables gives you the ability to find answers without needing to add the same number multiple times. It can be so much faster with multiplication.
Let’s look at an example. Let's say you wanted to find out how much 3 groups of 24 make. Sure, you could do it like this:
24 + 24 + 24 =72.
Or you can use the multiplication table and do it like this: 3 × 24 = 72 - using the table of 24.
Here’s how, once you have started working with your multiplication tables from 21 to 30, that will help you:
You will quickly and accurately be able to solve bigger math problems
You will gain a clearer understanding of division, as it's the opposite of multiplication
You will feel more comfortable with larger numbers
You will be prepared for harder math topics like percentages, ratios, algebra, and geometry
In each of your tables, you will always notice the way the table gives a number in an incremental manner. For example, the table of 25 gives you:
25, 50, 75, 100, and so on - constantly adding 25 again and again.
If you can quickly and accurately review or practice multiplication facts by simply using your multiplication fact tables from 21 to 30 you will absolutely increase your speed and accuracy when solving math problems at school and in your daily life.
Next, we will review the multiplication fact tables of 21 to 30 in which you will multiply each number 1 - 15 and you will also develop your multiplication and number sense.
