Introduction

When it comes to mathematics, understanding the basics is crucial. However, many students struggle with the concept of multiplication, especially when it comes to expressions like "x 3 x". In this article, we'll dive into what this expression means and how to solve it.

The Basics of Multiplication

Before we can tackle "x 3 x", let's review the basics of multiplication. Multiplication is a mathematical operation that involves combining two or more numbers to get a product. For example, 2 x 3 = 6, which means that if we have two groups of three, we end up with six in total.

The Meaning of "x"

In multiplication, the symbol "x" is used to represent the operation itself. For example, if we have 2 x 3, we're saying that we want to combine two groups of three. However, "x" can also represent a variable or an unknown value.

The Expression "x 3 x"

Now that we understand the basics of multiplication and the meaning of "x", let's look at the expression "x 3 x". This expression can be interpreted in different ways depending on the context. However, in most cases, it means that we want to multiply the value of "x" by 3 and then multiply the result by "x" again.

An Example

To understand this concept better, let's look at an example. Let's say that "x" is equal to 2. If we plug this value into the expression "x 3 x", we get: 2 x 3 x 2 = 2 x 3 x 2 = 12 So, when "x" is equal to 2, the expression "x 3 x" is equal to 12.

Solving "x 3 x"

Now that we understand what "x 3 x" means, let's look at how to solve it. To solve this expression, we need to follow the order of operations, which is the set of rules that tells us which operations to perform first.

The Order of Operations

The order of operations is as follows: 1. First, we perform any calculations inside parentheses. 2. Next, we perform any exponents or roots. 3. Then, we perform any multiplication or division, from left to right. 4. Finally, we perform any addition or subtraction, from left to right.

Applying the Order of Operations

To solve "x 3 x", we need to apply the order of operations. First, we need to perform the multiplication: x 3 x = (x x 3) x Now, we can simplify the expression: x x 3 = 3x So, the final expression is: 3x x = 3x^2

Another Example

Let's say that "x" is equal to 4. If we plug this value into the expression "x 3 x", we get: 4 3 4 = (4 x 3) x 4 = 12 x 4 = 48 So, when "x" is equal to 4, the expression "x 3 x" is equal to 48.

Conclusion

In conclusion, "x 3 x" is an expression that involves multiplying the value of "x" by 3 and then multiplying the result by "x" again. To solve this expression, we need to follow the order of operations, which tells us to perform multiplication before addition. By understanding the basics of multiplication and the order of operations, we can easily solve expressions like "x 3 x" and build a strong foundation for more advanced mathematical concepts.
