Algebraic expressions are a fundamental concept in mathematics, and understanding them is crucial for solving various mathematical problems. In this article, we will delve into the world of algebraic expressions, focusing on the distributive property and its applications.

What are Algebraic Expressions?

Algebraic expressions are a combination of variables, constants, and mathematical operations. They are used to represent a value or an expression that can be evaluated to a specific number. Algebraic expressions can be simple or complex, depending on the number of variables and operations involved.

The Distributive Property

The distributive property is a fundamental concept in algebra that allows us to expand expressions by multiplying each term inside the parentheses with the term outside the parentheses. The distributive property can be applied to both addition and subtraction.

(i) $5(6+4)=50$

Let's start with the first example: $5(6+4)=50$ . To evaluate this expression, we need to apply the distributive property. The distributive property states that:

$a(b+c) = ab + ac$

In this case, $a = 5$ , $b = 6$ , and $c = 4$ . Applying the distributive property, we get:

$5(6+4) = 5 \times 6 + 5 \times 4 = 30 + 20 = 50$

(ii) $5(6-4)=1$

Now, let's consider the second example: $5(6-4)=1$ . Again, we need to apply the distributive property. The distributive property states that:

$a(b-c) = ab - ac$

In this case, $a = 5$ , $b = 6$ , and $c = 4$ . Applying the distributive property, we get:

$5(6-4) = 5 \times 6 - 5 \times 4 = 30 - 20 = 10$

Understanding the Tabular Representation

The distributive property can be represented in a tabular format, as shown below:

	$(5 \times 6)+(5 \times 4)=50$	$(5 \times 6)-(5 \times 4)=10$
$\therefore a(b+c)=$	$(5 \times 6)+(5 \times 4)=50$
$\therefore a(b-c)=$		$(5 \times 6)-(5 \times 4)=10$
	$(5 \times 6)$	$(5 \times 6)$
	$(5 \times 4)$	$-(5 \times 4)$

In this tabular representation, we can see that the distributive property is applied to both addition and subtraction. The expression $(5 \times 6)+(5 \times 4)=50$ represents the distributive property for addition, while the expression $(5 \times 6)-(5 \times 4)=10$ represents the distributive property for subtraction.

Real-World Applications

The distributive property has numerous real-world applications. In mathematics, it is used to simplify complex expressions and solve equations. In science, it is used to model real-world phenomena, such as the motion of objects and the behavior of electrical circuits.

Conclusion

In conclusion, the distributive property is a fundamental concept in algebra that allows us to expand expressions by multiplying each term inside the parentheses with the term outside the parentheses. Understanding the distributive property is crucial for solving various mathematical problems and has numerous real-world applications. By applying the distributive property, we can simplify complex expressions and solve equations, making it an essential tool for mathematicians and scientists alike.
