Oct 11, 2025 by ADMIN 51 views

Hey guys! Ready to dive into some math problems that are not just about numbers, but also about real-world scenarios? We're going to break down some calculations and even touch on the dimensions of a car park. Let's get started!

Decoding the First Math Problem: A Step-by-Step Guide

Okay, let's tackle the first problem. We're dealing with (39 844 : 7 + 20 864 : 8) · 20 - 6 987 · 9. Don't worry, it looks a bit intimidating at first, but we'll break it down step by step. Remember the order of operations: parentheses first, then division and multiplication (from left to right), and finally, addition and subtraction (from left to right). It is very important to remember the order of operations; otherwise, you will get the wrong answer.

First, let's handle the divisions inside the parentheses. We have 39 844 : 7 and 20 864 : 8. Doing the math, 39 844 / 7 = 5692 and 20 864 / 8 = 2608. Now, our expression inside the parentheses becomes 5692 + 2608. Adding these two numbers together, we get 8300. Now our problem looks like this: 8300 · 20 - 6 987 · 9.

Next up, multiplication! We have 8300 * 20 and 6 987 * 9. Calculating these, we find that 8300 * 20 = 166000 and 6 987 * 9 = 62883. Now, we are down to the last operation: subtraction. Our problem simplifies to 166000 - 62883. Subtracting, we get 103117. So, the answer to the first math problem is 103117. See? Not so scary once you break it down. The correct answer should be: 103117. Keep in mind that understanding the order of operations is really essential to correctly solve math problems.

I hope you have understood the first problem and the process involved. If you are preparing for an exam, I advise you to take your time, and don't rush. With a little bit of patience, you can solve math problems easily. Many times, we tend to rush, and in doing so, we make silly mistakes, and we don't want that.

Cracking the Second Calculation: More Math Adventures

Alright, let's move on to the second math problem: 6 · (123 115 : 5 - 22 757 : 7) : 8 + 7 981. Once again, let's apply our trusty order of operations. We will start with the parentheses. Inside the parentheses, we have 123 115 : 5 - 22 757 : 7. That means, first the divisions. So, 123 115 / 5 = 24623 and 22 757 / 7 = 3251. Now our expression inside the parentheses simplifies to 24623 - 3251. Subtracting, we get 21372. Now the problem looks like this: 6 · 21372 : 8 + 7 981.

Now, let's do multiplication and division from left to right. We have 6 * 21372 = 128232. Then, we do the division: 128232 / 8 = 16029. The problem is now: 16029 + 7 981. Finally, we add these two numbers together: 16029 + 7 981 = 24010. And there you have it, guys! The answer to the second math problem is 24010. Again, the order of operations keeps us on track, and it helps us to make sure that we arrive at the correct answer. The order of operations is a very crucial part of the process of solving problems, so make sure you don't get confused.

It's a good idea to write down each step, especially when dealing with complex problems. It can help prevent errors and make it easier to track down any mistakes you might make. Also, you can use a calculator to check your results.

Car Park Dimensions: A Practical Application

Now, let's move on to the practical application. The problem states that the car park has the form of a rectangle. This means that we can find the area if we know its length and width. Knowing the length and width will allow us to solve the problem. So, let's talk about calculating the area of a rectangular car park. The area of a rectangle is found by multiplying its length by its width. For instance, if a car park is 20 meters long and 10 meters wide, its area would be 20 * 10 = 200 square meters. This kind of knowledge can be super useful for planning, whether you're designing a car park, buying a new home, or just figuring out how much space you have in your room. Understanding basic geometry is really handy.

If the area is known, and either the length or width is known, it's possible to calculate the other side by using the formula: Width = Area / Length or Length = Area / Width. This allows you to determine unknown dimensions. For instance, if the area is known, and the length is known, you can calculate the width by dividing the area by the length. So, you can calculate the width by using the formula.

Further Math Tips and Tricks

Here are some extra tips and tricks to help you master math problems:

Practice Regularly: The more you practice, the better you'll get. Do a little math every day, even if it's just for a few minutes.
Understand the Concepts: Don't just memorize formulas; understand why they work. This will help you solve problems in different ways.
Break Down Problems: Complex problems can be broken down into smaller, more manageable steps. This can make them seem less daunting.
Use Visual Aids: Diagrams, drawings, and other visual aids can help you understand problems better, especially in geometry.
Check Your Work: Always check your answers, either by doing the problem again or by using a calculator. This will help you catch any mistakes.

Also, don't be afraid to ask for help! If you're stuck on a problem, ask a teacher, a friend, or a family member for help. There are also many online resources available.

I hope this article has helped you to understand the math problems and the practical applications of math. Remember, math is a very important subject, and it can be fun when you know how to solve problems. If you follow these steps, you will be able to succeed in math, no matter what.
