Which Of The Following Expressions Has A Value Of 4

Which of the Following Expressions Has a Value of 4? A Comprehensive Guide

This article will explore different mathematical expressions and determine which ones evaluate to 4. We'll cover various operations, including addition, subtraction, multiplication, division, and order of operations (PEMDAS/BODMAS). Understanding these concepts is crucial for solving mathematical problems efficiently and accurately. This guide is perfect for students learning algebra, or anyone looking to brush up on their basic math skills.

Understanding Order of Operations (PEMDAS/BODMAS)

Before we begin evaluating expressions, let's refresh our understanding of the order of operations. This ensures we get the correct answer consistently. The acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction) helps us remember the sequence:

1. Parentheses/Brackets: Solve any expressions within parentheses or brackets first.
2. Exponents/Orders: Calculate any exponents (powers) or roots.
3. Multiplication and Division: Perform multiplication and division from left to right.
4. Addition and Subtraction: Perform addition and subtraction from left to right.

Analyzing Expressions to Find a Value of 4

Let's analyze several expressions and see which ones equal 4. We'll need to provide example expressions to analyze. Please provide the expressions you'd like me to evaluate. For instance, you could give me a list like this:

• 2 + 2
• 8 / 2
• 10 - 6
• (6 + 2) / 2
• 1 + 3

Once you provide the expressions, I will:

• Step-by-step solution: Clearly demonstrate the steps involved in evaluating each expression, following the order of operations.
• Explanation: Provide a concise explanation of the mathematical operations used.
• Identification of the correct answer: Clearly indicate which expression(s) result in a value of 4.

This detailed approach will not only answer your question but also enhance your understanding of mathematical problem-solving. I look forward to helping you!
