Introduction

Mathematics is a subject that has been a part of human life for centuries. It has been used to solve problems, make predictions, and even create art. However, math can also be a challenging subject, especially when it comes to solving equations and finding the right solutions. In this article, we will discuss a math trick that can help you simplify your life and make math more enjoyable. This trick is called "9 can add by taking LCM" or "cross multiplication." It is a simple yet powerful technique that can be used to solve a wide range of math problems.

What is LCM?

Before we dive into the math trick, let's first understand what LCM is. LCM stands for Least Common Multiple. It is the smallest multiple that two or more numbers have in common. For example, the LCM of 6 and 8 is 24, because 24 is the smallest number that both 6 and 8 can divide into evenly.

How to Use LCM to Add 9

Now that we know what LCM is, let's talk about how to use it to add 9. The trick is to take the LCM of two numbers and add 9 to it. This will give you the sum of the two numbers. For example, let's say we want to add 3 and 6. The LCM of 3 and 6 is 6, so we add 9 to it, which gives us 15. Therefore, 3 + 6 = 15.

Cross Multiplication

Another way to use LCM to add 9 is through cross multiplication. This involves multiplying the two numbers together and then adding 9 to the result. For example, let's say we want to add 4 and 5. We multiply 4 and 5 together, which gives us 20. Then, we add 9 to it, which gives us 29. Therefore, 4 + 5 = 29.

Benefits of Using LCM to Add 9

Using LCM to add 9 has several benefits. Firstly, it is a simple and easy-to-use technique that can be applied to a wide range of math problems. Secondly, it can help you to simplify complex equations and make math more enjoyable. Finally, it can also help you to develop your problem-solving skills and think creatively.

Examples of Using LCM to Add 9

Here are a few examples of using LCM to add 9:

2 + 7 = ? (LCM of 2 and 7 is 14, so 2 + 7 = 14 + 9 = 23)
5 + 3 = ? (LCM of 5 and 3 is 15, so 5 + 3 = 15 + 9 = 24)
9 + 2 = ? (LCM of 9 and 2 is 18, so 9 + 2 = 18 + 9 = 27)

Tips and Tricks

Here are a few tips and tricks to help you use LCM to add 9 effectively:

Make sure to find the LCM of the two numbers before adding 9 to it.
Use cross multiplication to simplify complex equations.
Practice using LCM to add 9 regularly to develop your problem-solving skills.
Use LCM to add 9 to solve a wide range of math problems, from simple addition to complex equations.

Conclusion

In conclusion, using LCM to add 9 is a simple yet powerful math trick that can help you simplify your life and make math more enjoyable. It is a technique that can be used to solve a wide range of math problems, from simple addition to complex equations. By following the tips and tricks outlined in this article, you can develop your problem-solving skills and think creatively. So, next time you encounter a math problem, try using LCM to add 9 and see how it can help you simplify your life.
