Understanding the Problem

When we're faced with a problem like 87472 multiplied by 12, it’s essential to understand what we're actually doing. Multiplication, at its core, is a shortcut for repeated addition. So, when we say 87472 x 12, we mean adding 87472 to itself 12 times. Now, nobody wants to do that manually, right? That’s why we have efficient multiplication methods.

Before we jump into the step-by-step solution, let's quickly recap some multiplication basics. You probably remember these from elementary school, but a quick refresher never hurts!

• Multiplicand: The number being multiplied (in this case, 87472).
• Multiplier: The number by which the multiplicand is multiplied (in this case, 12).
• Product: The result of the multiplication (what we're trying to find).

Knowing these terms helps us break down the problem and communicate our solution clearly. Now that we're all on the same page, let's get into the nitty-gritty of solving 87472 x 12. We’ll walk through the process step by step, making sure you understand each part. Trust me; by the end of this, you'll be a multiplication master!

Step-by-Step Solution

Okay, guys, let's break down how to solve 87472 x 12 step-by-step. This will make it super easy to follow along. We’re going to use the standard multiplication method, which you probably learned back in school. Don't worry; it’s straightforward once you get the hang of it!

Step 1: Multiply by the Ones Digit

First, we take the ones digit of the multiplier (which is 2 in 12) and multiply it by each digit of the multiplicand (87472), starting from the right.

• 2 x 2 = 4
• 2 x 7 = 14 (write down 4, carry over 1)
• 2 x 4 = 8 + 1 (carried over) = 9
• 2 x 7 = 14 (write down 4, carry over 1)
• 2 x 8 = 16 + 1 (carried over) = 17

So, the result of this step is 174944. Make sure you write it down neatly, as this is our first partial product. Keeping your numbers aligned will help prevent errors later on. Now, let's move on to the next step!

Step 2: Multiply by the Tens Digit

Next, we take the tens digit of the multiplier (which is 1 in 12) and multiply it by each digit of the multiplicand (87472). Since we're multiplying by the tens digit, we need to add a zero as a placeholder in the ones place of our second partial product. This is super important because it ensures that we're multiplying by 10, not just 1.

• 1 x 2 = 2 (write it down with a zero placeholder: 20)
• 1 x 7 = 7 (write it down: 720)
• 1 x 4 = 4 (write it down: 4720)
• 1 x 7 = 7 (write it down: 74720)
• 1 x 8 = 8 (write it down: 874720)

So, the result of this step, with the zero placeholder, is 874720. Again, make sure everything is aligned correctly. Now, we're ready for the final step!

Step 3: Add the Partial Products

Finally, we add the two partial products we calculated in the previous steps:

  174944
+ 874720
--------
 1049664

So, 174944 + 874720 = 1049664. This is the final result of our multiplication!

Final Answer

After going through all the steps, we've found that 87472 multiplied by 12 equals 1049664. Woo-hoo! You’ve successfully solved the problem.

Alternative Methods for Multiplication

Okay, so we tackled the 87472 x 12 problem using the standard multiplication method. But hey, it's always good to have a few tricks up your sleeve, right? Let's explore some alternative methods you can use to double-check your work or just mix things up a bit.

The Lattice Method

The lattice method is a visually appealing way to multiply numbers. It's especially handy for larger numbers because it helps keep everything organized. Here’s a quick rundown:

1. Draw a Grid: Create a grid with rows and columns corresponding to the digits of the numbers you're multiplying. For 87472 x 12, you'll have a 5-column grid and a 2-row grid.
2. Divide Each Cell: Draw a diagonal line through each cell, splitting it into two triangles.
3. Multiply and Fill: Multiply each digit of one number by each digit of the other number, placing the tens digit in the upper triangle and the ones digit in the lower triangle.
4. Add Diagonally: Starting from the bottom right, add the numbers along each diagonal. If you get a two-digit number, carry over the tens digit to the next diagonal.
5. Read the Result: Read the result from left to right along the top and down the right side of the grid.

While it might sound complicated, it's actually pretty straightforward once you try it. Plus, it’s a fun way to visualize multiplication!

Breaking Down the Numbers

Another method is to break down the numbers into smaller, more manageable parts. For example, you can break down 12 into 10 + 2. Then, multiply 87472 by 10 and 87472 by 2, and add the results.

• 87472 x 10 = 874720
• 87472 x 2 = 174944
• 874720 + 174944 = 1049664

This method can be particularly useful if you find it easier to multiply by multiples of 10. It’s all about finding what works best for you!

Using a Calculator

Okay, this might seem like a no-brainer, but it's worth mentioning. Using a calculator is the quickest way to solve 87472 x 12. Just punch in the numbers and hit the equals button. But remember, it’s still important to understand the underlying math. Calculators are great for quick calculations, but knowing how to do it manually helps you catch errors and understand the process.

Real-World Applications of Multiplication

So, we've nailed how to solve 87472 x 12, but you might be wondering, "When am I ever going to use this in real life?" Well, multiplication is everywhere! Here are a few examples:

Calculating Costs

Imagine you're buying 12 items that each cost $874.72. To find the total cost, you'd multiply 874.72 by 12. This is super useful for budgeting, shopping, and managing your finances.

Measuring Areas and Volumes

When you're figuring out the area of a rectangular room (length x width) or the volume of a box (length x width x height), you're using multiplication. This is essential for home improvement projects, gardening, and even packing efficiently.

Scaling Recipes

If you want to double or triple a recipe, you need to multiply the amount of each ingredient by the scaling factor. So, if a recipe calls for 87472 grams of flour and you want to make 12 times the recipe, you'll multiply 87472 by 12.
