GoMim AI | What is distributive property and How to Calculate it

Introduction

The distributive property is a fundamental concept in mathematics that plays a crucial role in simplifying expressions and solving equations. It is widely used in various fields such as algebra, calculus, and even computer programming. Understanding the distributive property can help students excel in their math exams and apply mathematical reasoning in real-world situations.

What is it?

The distributive property is a rule in mathematics that helps to simplify expressions and solve equations. It involves the distribution of multiplication over addition or subtraction within an expression. Mathematically, it can be expressed as: $$ a(b + c) = ab + ac $$ This means that if you multiply a number by a sum, you can multiply each addend separately by the number and then add the products. This property is equally applicable for subtraction: $$ a(b - c) = ab - ac $$

Why is it important?

The distributive property is important because it simplifies complex mathematical problems, making them easier to solve. It is essential for algebraic manipulations, particularly in expanding expressions, solving equations, and factoring. In real-life applications, engineers use the distributive property to calculate loads and forces, economists use it in financial modeling, and it is also fundamental in computer algorithms and data analysis. This property is frequently tested in standardized exams, making it critical for students to understand and apply it effectively.

How to Calculate it Step-by-Step

To calculate using the distributive property, follow these steps:

1. Identify the expression: Look for terms in the form of \( a(b + c) \) or \( a(b - c) \).

2. Apply the property: Distribute the multiplication over each term inside the parentheses.

3. Simplify the expression: Perform the multiplications and then combine the results.

Example:

Calculate \( 3(x + 4) \).

- Step 1: Identify the expression, which is \( 3(x + 4) \).

- Step 2: Distribute the multiplication: \( 3 \times x + 3 \times 4 \).

- Step 3: Simplify: \( 3x + 12 \).

So, \( 3(x + 4) = 3x + 12 \).

Related Practice Problem

Problem: Simplify the expression using the distributive property: \( 5(y - 2) \).

Step-by-step Solution:

Step 1: Identify the expression, which is \( 5(y - 2) \).

Step 2: Apply the distributive property:

- Multiply \( 5 \) by \( y \): \( 5y \).

- Multiply \( 5 \) by \( -2 \): \( -10 \).

Step 3: Combine the results: \( 5y - 10 \).

Therefore, \( 5(y - 2) = 5y - 10 \).
