So, let's jump in and unravel the solution together!

Understanding the Order of Operations: The Foundation

Before we jump into the numbers, let's quickly review the order of operations. This is super important, guys! The order of operations tells us the sequence in which we should solve a mathematical expression. It's often remembered by the acronym PEMDAS or BODMAS. Let's break it down:

  • Parentheses / Brackets: Solve anything inside parentheses or brackets first.
  • Exponents / Orders: Deal with exponents or powers next.
  • Multiplication and Division: Perform these from left to right.
  • Addition and Subtraction: Finally, do addition and subtraction from left to right.

So, in our problem (25×51 - 25×2), we'll first handle the multiplication parts, and then we'll tackle the subtraction. Understanding this order ensures we get the correct answer. It’s like a roadmap for solving the problem, guiding us step by step. This method ensures that everyone gets the same, correct answer, no matter who solves it. Following the rules is crucial to avoid getting the wrong result. Remembering PEMDAS or BODMAS is the key to correctly solving all the math expressions. This framework prevents confusion and makes sure that you always get the right answer. Keeping this order in mind will make it easy to tackle more complex problems later on. We always need to keep these rules in mind as we solve mathematical equations. Understanding the rules is the first step to solving any math problem. Now that we've refreshed our memory on the order of operations, we're ready to move on to the problem itself. Are you ready? Let's get to it!

Step-by-Step Solution: Unpacking 25×51 - 25×2

Alright, now for the fun part! Let's solve the problem 25×51 - 25×2 step by step. We'll break it down so that it's easy to follow. First, let's focus on the multiplication parts. We have two multiplication problems: 25×51 and 25×2. Let's do each one separately:

  1. Calculate 25 × 51:

    • You can do this in a couple of ways. You could multiply it longhand, or you could break it down. For example, you could think of 51 as (50 + 1). So, 25 × 51 becomes (25 × 50) + (25 × 1).
    • 25 × 50 = 1250 (Think: 25 times 5 is 125, then add a zero).
    • 25 × 1 = 25.
    • Add those two together: 1250 + 25 = 1275.
    • So, 25 × 51 = 1275.
  2. Calculate 25 × 2:

    • This one is super simple: 25 × 2 = 50.
  3. Now, put it all together:

    • Our original problem was 25 × 51 - 25 × 2. We've calculated those two multiplication parts.
    • Substitute the values: 1275 - 50.
    • Subtract: 1275 - 50 = 1225.

So, the answer is 1225! See? It wasn't that hard. We broke it down into smaller, more manageable steps and were able to solve the problem. It all comes down to breaking the problem into smaller pieces. This methodical approach makes it easy to understand and ensures accuracy. We carefully went through each calculation so that you could easily follow the logic. Each step is clear and easy to follow. Now, we can confidently move on to the next step. We have now solved the main expression; let's explore some of the other ways to solve it.

Using the Distributive Property: A Clever Shortcut

Alright, guys, here's a cool trick! There's another way to solve this problem that's even faster, and it involves something called the distributive property. The distributive property says that a(b - c) = ab - ac. In our case, we have something similar: 25×51 - 25×2. Notice that 25 is multiplied by both 51 and 2. This is where the distributive property comes into play. Here’s how we can apply it:

  1. Identify the common factor: In our expression, the common factor is 25.
  2. Rewrite the expression: We can rewrite 25 × 51 - 25 × 2 as 25 × (51 - 2). This is the reverse of the distributive property.
  3. Simplify inside the parentheses: Calculate 51 - 2 = 49.
  4. Multiply: Now, we just need to calculate 25 × 49.
    • You can do this by breaking it down: 25 × (50 - 1) = (25 × 50) - (25 × 1) = 1250 - 25 = 1225.

See? We got the same answer, 1225, but using a slightly different method. The distributive property can save you some time and effort when you spot this pattern in the problem. This method makes calculations easier and faster. It shows that there are different ways to solve the same mathematical problem. This shortcut is a great way to improve your skills and make solving complex problems more efficient. Understanding the distributive property can be an advantage in other calculations too. This property can be an invaluable tool for solving various algebraic equations. By spotting these patterns, we can solve complex problems more efficiently. Remember, in math, there's usually more than one way to get to the right answer. By understanding different approaches, you'll be able to tackle problems with greater confidence. Let’s now summarize what we have done and recap all the information.

Conclusion: Key Takeaways and Practice

So, we've solved the problem 25×51 - 25×2 in a couple of ways! We broke it down step by step, ensuring you understood the order of operations and the basic multiplication and subtraction. Then, we used the distributive property to solve it even faster. Let's recap the key takeaways:
