Calculating $12(8+9)$: A Step-by-Step Guide

Hey guys! Today, we're going to break down a common math problem: calculating the value of the expression $12(8+9)$. It might seem a bit daunting at first, but trust me, it's super manageable once you understand the basic principles. We'll walk through it step by step, so you can confidently tackle similar problems in the future. Let's dive in!

Understanding the Order of Operations

Before we jump into solving this specific problem, it's crucial to understand the order of operations. This is the golden rule in mathematics that tells us which operations to perform first. You might have heard of the acronym PEMDAS, which stands for:

• Parentheses
• Exponents
• Multiplication and Division (from left to right)
• Addition and Subtraction (from left to right)

This order is super important because doing things out of order can lead to a completely wrong answer. Think of it like a recipe – you can't bake the cake before you mix the ingredients, right? The same logic applies here. So, keep PEMDAS in the back of your mind as we go through the steps.

In the context of $12(8+9)$, PEMDAS tells us that we need to deal with what's inside the parentheses first. This is a fundamental principle in mathematics, ensuring that we solve expressions in a consistent and logical manner. Ignoring the order of operations would be like trying to read a book starting from the middle – it just wouldn't make sense! By adhering to PEMDAS, we ensure that our calculations are accurate and our final answer is correct. This foundation is essential for tackling more complex mathematical problems later on, so it's worth getting comfortable with it now. Remember, math is like building blocks – you need a solid base to construct something amazing!

Step 1: Solve the Parentheses

Our expression is $12(8+9)$. According to PEMDAS, we need to tackle the parentheses first. Inside the parentheses, we have $8 + 9$. This is a simple addition problem, so let's add those numbers together. What do we get? 8 plus 9 equals 17. So, we've simplified the expression inside the parentheses to 17. Now, our expression looks like this: $12(17)$. See how much simpler it's becoming already? We're making progress!

This step is crucial because it isolates the value within the parentheses, allowing us to proceed with the rest of the calculation. Think of it like clearing the clutter before you start a project – it makes everything else much easier. By focusing on the parentheses first, we're following the logical flow of mathematical operations and setting ourselves up for success. This seemingly small step has a significant impact on the overall solution, so it's essential to get it right. Plus, it feels good to tick off the first item on our PEMDAS checklist, right? We're on our way to cracking this problem!

Step 2: Multiplication

Now that we've simplified the parentheses, our expression is $12(17)$. The parentheses here mean multiplication. So, what we really have is 12 multiplied by 17. This is the next operation we need to perform according to PEMDAS. Multiplication is like repeated addition, so we're essentially adding 17 to itself 12 times. You could do this manually, but that would take a while! Let's use our multiplication skills to make it easier. 12 multiplied by 17… Time to put on our thinking caps!

This is where knowing your multiplication tables or having a calculator handy can be super helpful. Don't be afraid to use the tools available to you – math is about understanding the concepts, not necessarily memorizing every single calculation. But if you're up for the challenge, multiplying 12 by 17 manually is a great way to practice your arithmetic skills. Either way, the key is to perform the multiplication accurately. This step is the linchpin of the entire problem, as it combines the results of the previous step to arrive at the final answer. So, let's make sure we get it right!

Step 3: Calculate 12 * 17

Alright, let's calculate 12 multiplied by 17. You can do this using the standard multiplication method, or even use a calculator if you prefer. If we multiply 12 by 17, we get 204. So, $12 * 17 = 204$. Great job! We've successfully performed the multiplication. This is a significant step, and we're almost at the finish line. We're taking this problem down, one step at a time!

This step demonstrates the power of multiplication as a shortcut for repeated addition. Instead of adding 17 twelve times, we can simply multiply the two numbers together to get the same result much more efficiently. This is one of the beautiful things about math – it provides us with tools and techniques to simplify complex calculations. And in this case, it's brought us one step closer to our final answer. We're building momentum, guys! Keep going!

The Final Answer

So, we've gone through all the steps. We first solved the parentheses: $8 + 9 = 17$. Then, we multiplied 12 by 17, which gave us 204. That means the value of the expression $12(8+9)$ is 204. And that's our final answer! Woohoo! We did it!

This is the moment of triumph, the culmination of all our hard work. We've successfully navigated the problem, followed the order of operations, and arrived at the correct solution. It's a great feeling, isn't it? This final answer represents the complete and accurate solution to the original problem, and it's a testament to our understanding of mathematical principles. Pat yourselves on the back, guys – you've earned it!

Let's Recap

To recap, we solved the expression $12(8+9)$ by following the order of operations (PEMDAS). First, we added the numbers inside the parentheses: $8 + 9 = 17$. Then, we multiplied 12 by the result, 17, which gave us 204. Therefore, the value of $12(8+9)$ is 204. Remember, the key to solving math problems is to break them down into smaller, more manageable steps. And always keep PEMDAS in mind! You've got this!

This recap serves as a reminder of the journey we've taken, reinforcing the steps and the logic behind them. It's like reviewing your notes after a lecture – it helps to solidify the information in your mind. By summarizing the process, we're ensuring that we not only understand the solution to this specific problem but also the underlying principles that can be applied to other similar problems. This is the essence of learning mathematics – it's not just about memorizing formulas, it's about understanding the concepts and how to apply them. So, let's carry this knowledge forward and continue our mathematical adventures!

Practice Makes Perfect

The best way to get comfortable with math is to practice! Try solving similar expressions on your own. For example, you could try $15(6+4)$ or $8(11+3)$. Remember to follow PEMDAS, and you'll be a pro in no time. Math is like a muscle – the more you use it, the stronger it gets. So, don't be afraid to challenge yourself and keep practicing. You might even start to enjoy it! And who knows, maybe you'll discover a hidden talent for mathematics. The possibilities are endless!

This call to action encourages further learning and reinforces the idea that practice is the key to mastery. It's like learning a new language – you can't become fluent just by reading a textbook, you need to speak and practice regularly. The same applies to mathematics.
