Hey there, math enthusiasts! Today, we're diving into a cool little number puzzle: "What is the result of subtracting 789 from a number whose value is 120 less than 1000?" Sounds a bit tricky, right? But don't sweat it – we'll break it down step by step to make it super clear and easy to understand. We'll use our mathematical skills to unravel this problem. Get ready to flex those brain muscles! This is a great exercise for anyone looking to sharpen their arithmetic skills, whether you're a student, a teacher, or just someone who loves a good mental challenge. Let's get started!

Decoding the Problem

Alright, guys, let's start by figuring out what the question is really asking. The core of the problem involves two main steps: first, finding the original number, and second, subtracting 789 from it. The question gives us a clue: the number is 120 less than 1000. That's our starting point. This initial number is what we need to determine before we can proceed with the subtraction. It's like finding the treasure before we can count the gold. So, we'll start with mathematical operations to find this unknown number. Understanding the wording is key here. Make sure we all have a handle on this, the first part is really about understanding the mathematical relationships. We are going to go through a straightforward process, so that we can easily solve this problem, so we can finally find out the answer.

Before we dive into the calculations, let's make sure we all understand the question. The question involves a two-part process. The first part requires us to find a number that, when reduced by 120, yields 1000. It is therefore crucial to remember the steps that are required to get the correct answer. The second part involves the subtraction of 789 from the number found. We’ll carefully break down each step so that you can confidently solve similar problems in the future. We'll focus on how to use the information given to us, and apply our mathematical understanding to solve this problem.

Now, let's transform the wording into a mathematical statement. What is the number which when we deduct 120 from it, the result is 1000? Let's turn this into an equation. We can express this as: x - 120 = 1000. Here, x represents our unknown number. Understanding the relationship between the words and the symbols is half the battle won. In the following sections, we are going to explore different steps for calculation, so you will understand the question in a better way. This will greatly help to solidify the concepts we are discussing here.

Finding the Original Number

So, how do we find x? This is where our basic mathematical skills come into play. If we have x - 120 = 1000, we need to isolate x to find its value. To do this, we need to get rid of the -120 on the left side of the equation. And the way to do this is to add 120 to both sides of the equation. This maintains the balance of the equation. By adding 120 to both sides, the equation becomes: x - 120 + 120 = 1000 + 120. Guys, remember that whatever you do on one side, you must also do on the other side to keep things balanced.

Simplifying this, we get x = 1120. That's the original number! So, the number that is 120 less than 1000 is actually 1120. See? Not so hard, right? This step is a fundamental concept in mathematics known as solving linear equations. You'll use this skill over and over again in your math journey. Now that we've successfully found the original number. Keep in mind that we're using basic arithmetic operations – addition and subtraction – to solve a problem that might seem complex at first glance. Make sure to understand the fundamental concept we use here. Understanding how to manipulate equations to isolate unknowns is a core skill in algebra and is used extensively in mathematical problem-solving. This is just the beginning; there are more complex equations. Keep practicing!

Alright, now we know that the original number is 1120. Now, we're ready to move on to the second part of the problem. We found our first unknown which is 1120. Now our job is to calculate the result of the second part of the question. Remember, practice is key, and the more you work on these types of problems, the easier it will become. Don't worry if you don't get it perfectly the first time. We are working together here!

Subtracting 789

Now that we know the original number, the next step is straightforward: subtract 789 from 1120. This is a simple subtraction problem. So, what's 1120 - 789? We can do this either by hand, using a calculator, or even in our heads, depending on how comfortable we are with mental math. For those who prefer to do it manually, you can set up the subtraction like this:

1120

  • 789

If we start from the right (the ones place), we see that we can't subtract 9 from 0. So, we need to borrow from the tens place. However, the tens place also has a 2, so we need to borrow from the hundreds place first. The hundreds place becomes 0, the tens place becomes 11, and the ones place becomes 10. Then you will be able to perform calculations correctly.

Now, we subtract. 10 - 9 = 1. Then, in the tens place, 11 - 8 = 3. Finally, in the hundreds place, 10 - 7 = 3. So, the result is 331. Therefore, when we subtract 789 from 1120, we get 331. Therefore, subtracting 789 from the number (which we found to be 1120) yields the solution. See, we’re almost there! This is a good opportunity to review your subtraction skills, especially the concept of borrowing, which is often a source of confusion for beginners. If you're comfortable with mental math, you might have already figured this out in your head. Well done, if you did! The important thing is to understand the process. We are now able to calculate the answer!

The Final Answer

So, guys, we have the answer! The original number, which is 120 less than 1000, is 1120. Subtracting 789 from 1120 gives us 331.

  • Therefore, the answer is 331.
