Algebraic Expression: Translate The Phrase Correctly
Hey guys! Let's dive into translating word problems into algebraic expressions. It can feel like deciphering a secret code sometimes, but trust me, once you get the hang of it, it's super cool. We're going to break down a specific example: "six more than the product of five and a number, decreased by one." This type of problem is fundamental in algebra, laying the groundwork for more complex equation solving and mathematical reasoning. Mastering the translation of verbal phrases into mathematical expressions is crucial not only for academic success in mathematics but also for real-world problem-solving scenarios. For instance, it's used in budgeting, calculating costs, and even in basic programming logic. So, stick with me, and let's unlock this algebraic puzzle together!
Dissecting the Phrase: A Step-by-Step Approach
The key to tackling these problems is to break them down bit by bit. Think of it like untangling a knot – you wouldn't just yank it, right? You'd gently work through each loop. Let's do that with our phrase:
- "The product of five and a number": This is where we introduce our variable. Since we don't know the number, we'll call it 'n' (but you could use 'x', 'y', or any letter you like!). "Product" means multiplication, so this part translates to 5 * n, or simply 5n.
- "Six more than the product": Now we're adding 6 to our previous result. So, we have 5n + 6.
- "Decreased by one": Finally, we subtract 1 from the whole thing. This gives us our complete expression: 5n + 6 - 1.
See? Not so scary when we take it one step at a time. This methodical approach not only simplifies the process but also minimizes the chances of making errors. By identifying keywords and breaking down complex phrases into smaller, manageable parts, we can accurately represent mathematical relationships in algebraic form. This skill is vital for translating real-world scenarios into mathematical equations, allowing us to solve problems ranging from simple arithmetic to advanced calculus.
Why Order Matters: Unveiling the Math Hierarchy
One of the trickiest parts about translating phrases is getting the order right. Math has a specific order of operations (PEMDAS/BODMAS), and we need to respect that. Think of it like following a recipe – you can't just throw everything in at once and hope for the best! Understanding the order of operations is akin to understanding the grammar of mathematics; it dictates how different operations interact with each other. Parentheses, exponents, multiplication, division, addition, and subtraction must be performed in a specific order to arrive at the correct answer. For example, multiplication and division take precedence over addition and subtraction, meaning they should be performed first unless parentheses dictate otherwise. Let's look at why order is so crucial in our example:
- If we hadn't carefully considered the phrase, we might have incorrectly grouped things. For example, we could have misinterpreted "six more than the product" to mean 6 + 5 + n, which is totally different from 5n + 6. This highlights the importance of paying close attention to the wording and the relationships between different parts of the phrase. The phrase "six more than" implies that the addition of six should be performed after the product of five and a number is calculated. This distinction is critical for constructing the correct algebraic expression.
- The phrase "decreased by one" applies to the entire expression we built so far (5n + 6), not just a part of it. This is why the correct expression is 5n + 6 - 1, and not something like 5(n - 1) + 6, which would imply a different order of operations. The subtraction of one is the final operation performed, so it should be applied after all other operations have been accounted for. This requires a careful reading and understanding of the phrase to ensure that the algebraic expression accurately reflects the intended mathematical relationship.
By carefully considering the order of operations and how different parts of the phrase relate to each other, we can avoid common pitfalls and construct the correct algebraic expression. This attention to detail is what sets apart a correct solution from a potentially flawed one.
Simplifying the Expression: Making It Neat and Tidy
So, we've arrived at 5n + 6 - 1. While this is technically correct, we can simplify it further. Remember, in math, we always want to present our answers in the simplest form possible. It's like tidying up your room – it just looks better and is easier to work with! Simplifying algebraic expressions not only makes them more aesthetically pleasing but also more practical for further calculations and problem-solving. A simplified expression is easier to understand, manipulate, and use in subsequent mathematical steps.
In our case, we have two constant terms, 6 and -1. We can combine these by simply doing the subtraction: 6 - 1 = 5. This means our final, simplified expression is:
5n + 5
This is the most concise and clear way to represent "six more than the product of five and a number, decreased by one." This simplified form makes it easier to identify the key components of the expression and how they relate to each other. It also allows for easier substitution of values for the variable 'n' when solving equations or evaluating the expression under different conditions. Simplifying expressions is a fundamental skill in algebra and is essential for both accuracy and efficiency in mathematical problem-solving.
Identifying the Correct Option: Putting It All Together
Now, let's relate this back to the original question. We were given a few options, and we need to choose the one that matches our simplified expression, 5n + 5. By carefully dissecting the phrase and simplifying the resulting expression, we've equipped ourselves to confidently identify the correct answer. This process of elimination and validation is a crucial skill in mathematics, helping to ensure accuracy and confidence in one's solutions. In multiple-choice questions, like the one we're addressing, it's common for incorrect options to be designed to trap students who may have made common mistakes, such as misinterpreting the order of operations or incorrectly combining terms.
Looking at the options, we can see that:
- A. 6 + 5n - 1 simplifies to 5n + 5. This is our match!
- B. 6 + 5 + n - 1 simplifies to n + 10, which is incorrect.
- C. 6 + 5(n - 1) simplifies to 5n + 1, which is also incorrect.
- D. (6 + 5)n - 1 simplifies to 11n - 1, again, not our expression.
Therefore, option A is the correct answer. By systematically working through each step, from translating the phrase to simplifying the expression and then comparing it to the given options, we've demonstrated a comprehensive approach to solving this type of problem. This method not only helps in finding the correct answer but also builds a solid understanding of the underlying mathematical principles.
