Hey guys! Today, we're diving into a fun math problem that involves calculating the total number of books on three shelves. This is a classic example of a word problem that requires careful reading and a step-by-step approach to solve. So, let's break it down and figure out how many books we have in total.

Understanding the Problem

Before we jump into calculations, let's make sure we understand the problem clearly. We're told that there are three shelves in a bookshelf. The first shelf has 32 books. The number of books on the second shelf is 8 more than the first shelf. And the third shelf has 5 more books than the second shelf. Our goal is to find the total number of books on all three shelves. This type of problem is very common in mathematics, especially when learning about addition and problem-solving strategies. It's important to identify the key information and what the question is asking before attempting to solve it. Sometimes, drawing a simple diagram or writing down the knowns can help visualize the problem. This can prevent errors and make the problem seem less daunting. Remember, the most important step in solving any word problem is to understand it fully. So, take your time and read the problem carefully before moving on to the calculations.

Step 1: Books on the Second Shelf

The core of the problem lies in figuring out how many books are on each shelf before we can add them all up. Let's start with the second shelf. We know that the first shelf has 32 books, and the second shelf has 8 more books than the first. To find the number of books on the second shelf, we need to add 8 to the number of books on the first shelf. So, the calculation is: 32 + 8 = ?. This is a straightforward addition problem. You can solve it mentally, use your fingers, or write it down – whatever works best for you! Once we have the number of books on the second shelf, we can move on to the next step. This is a crucial step because the number of books on the third shelf depends on the number of books we find here. Accuracy is key in this step to ensure we get the correct answer for the entire problem. Remember, each step builds upon the previous one, so a mistake here can throw off the final result. Think of it as building a tower – each block needs to be placed correctly for the tower to stand tall and strong. So, let's carefully add 8 to 32 and get the number of books on the second shelf.

Step 2: Books on the Third Shelf

Now that we've figured out the number of books on the second shelf, let's move on to the third shelf. The problem states that the third shelf has 5 more books than the second shelf. This means we need to add 5 to the number of books we calculated for the second shelf. Let's say we found that the second shelf has 'X' books (you'll have the actual number from the previous step). To find the number of books on the third shelf, we'll calculate: X + 5 = ?. Again, this is a simple addition problem. Make sure you use the correct number 'X' that you calculated in the previous step. This step is just as important as the previous one. We're building upon our previous calculations, so accuracy is paramount. Imagine if we got the number of books on the second shelf wrong – then this calculation would also be wrong, leading to an incorrect final answer. Remember, mathematics is like a puzzle; each piece must fit perfectly for the whole picture to come together. So, let's take the number of books on the second shelf and carefully add 5 to find the number of books on the third shelf.

Step 3: Calculating the Total Number of Books

We're almost there! We've figured out the number of books on each of the three shelves. Now, the final step is to find the total number of books. To do this, we simply need to add the number of books on each shelf together. We know the first shelf has 32 books. Let's say we found that the second shelf has 'Y' books and the third shelf has 'Z' books (you'll have the actual numbers from the previous steps). The final calculation will be: 32 + Y + Z = ?. This is another addition problem, but this time we're adding three numbers together. You can add them in any order – the result will be the same. You can add 32 and Y first, and then add Z to the result. Or you can add Y and Z first, and then add 32. Choose the method that feels most comfortable for you. This step is the culmination of all our previous work. We've broken down the problem into smaller, manageable steps, and now we're bringing it all together to get the final answer. Think of it as the grand finale of a performance – all the practice and preparation have led to this moment. So, let's carefully add the number of books on each shelf and proudly present our final answer. Remember to double-check your work to ensure accuracy!

Solution

Let's walk through the solution step by step:

  1. Books on the Second Shelf: The first shelf has 32 books, and the second shelf has 8 more. So, 32 + 8 = 40 books on the second shelf.
  2. Books on the Third Shelf: The third shelf has 5 more books than the second shelf, which has 40 books. So, 40 + 5 = 45 books on the third shelf.
  3. Total Number of Books: Now, we add the number of books on each shelf: 32 (first shelf) + 40 (second shelf) + 45 (third shelf) = 117 books.

Therefore, there are a total of 117 books on all three shelves. Great job, guys! We successfully solved the problem by breaking it down into smaller steps and carefully performing each calculation. This approach is useful for tackling many mathematical problems, especially word problems. Always remember to read the problem carefully, identify the key information, and break the problem down into manageable steps. And don't forget to double-check your work to ensure accuracy. Keep practicing, and you'll become a pro at solving these types of problems!

Tips for Solving Word Problems

Word problems can sometimes seem intimidating, but with the right approach, they can be quite manageable. Here are some helpful tips to keep in mind when tackling word problems:

  • Read Carefully: This may sound obvious, but it's crucial to read the problem thoroughly and understand what it's asking. Don't rush through it. Take your time to absorb all the information provided.
  • Identify Key Information: Once you've read the problem, identify the key information. What are the knowns? What is the question asking you to find? Underline or highlight the important details.
  • Break It Down: Complex problems can be overwhelming. Break them down into smaller, more manageable steps. This will make the problem seem less daunting and easier to solve.
  • Choose the Right Operation: Determine which mathematical operation(s) you need to use to solve the problem. Are you adding, subtracting, multiplying, or dividing? Look for clue words like
