Write An Equivalent Expression To $(a \cdot B) - C$ Using The Associative Property Of Multiplication.

$$

Introduction

In mathematics, the Associative Property of Multiplication is a fundamental concept that allows us to rearrange the order of numbers in a multiplication expression without changing the result. This property is denoted as $(a \cdot b) \cdot c = a \cdot (b \cdot c)$, where $a$, $b$, and $c$ are any real numbers. In this article, we will explore how to use the Associative Property of Multiplication to write an equivalent expression to $(a \cdot b) - c$.

Understanding the Associative Property of Multiplication

Before we dive into the problem, let's take a closer look at the Associative Property of Multiplication. This property states that when we multiply three numbers together, the order in which we multiply them does not affect the result. In other words, $(a \cdot b) \cdot c = a \cdot (b \cdot c)$.

To illustrate this concept, let's consider an example. Suppose we want to multiply 2, 3, and 4 together. Using the Associative Property of Multiplication, we can write:

$(2 \cdot 3) \cdot 4 = 2 \cdot (3 \cdot 4)$

Using the multiplication rules, we can simplify both expressions:

$(2 \cdot 3) \cdot 4 = 6 \cdot 4 = 24$

$2 \cdot (3 \cdot 4) = 2 \cdot 12 = 24$

As we can see, both expressions yield the same result, which is 24. This demonstrates the Associative Property of Multiplication in action.

Writing an Equivalent Expression to $(a \cdot b) - c$

Now that we have a solid understanding of the Associative Property of Multiplication, let's apply it to write an equivalent expression to $(a \cdot b) - c$. We can start by rearranging the expression using the distributive property, which states that $a \cdot (b + c) = a \cdot b + a \cdot c$.

Using the distributive property, we can rewrite $(a \cdot b) - c$ as:

$a \cdot b - c = a \cdot (b - c)$

However, we want to use the Associative Property of Multiplication to write an equivalent expression. To do this, we can add a set of parentheses around the $a$ and $b$ terms, like this:

$a \cdot (b - c) = (a \cdot b) - (a \cdot c)$

Now, we can use the Associative Property of Multiplication to rearrange the expression. We can move the $a$ term to the left of the parentheses, like this:

$(a \cdot b) - (a \cdot c) = a \cdot (b - c)$

However, we want to write an equivalent expression using the Associative Property of Multiplication. To do this, we can add a set of parentheses around the $b$ and $c$ terms, like this:

$a \cdot (b - c) = a \cdot (c - b)$

Now, we can use the Associative Property of Multiplication to rearrange the expression. We can move the $a$ term to the left of the parentheses, like this:

$a \cdot (c - b) = (a \cdot c) - (a \cdot b)$

And there you have it! We have successfully written an equivalent expression to $(a \cdot b) - c$ using the Associative Property of Multiplication.
