If you’ve ever found yourself scratching your head over a math problem, you’re not alone! Let’s dig into a light-hearted challenge involving Sam's age—yes, mathematics can be fun after all! So, how can we figure out Sam’s age using a simple expression? Let’s break it down step-by-step; you’ll see that, with a little patience and clarity, math problems can be quite engaging.

Let’s Start With the Numbers

First things first, we’ve got a mathematical expression we need to work through: subtracting seven from twice 21, adding 11, and then dividing by 2. Does that sound complicated? Not at all! Let’s tackle it one step at a time.

  1. Twice 21: We start off with the phrase "twice 21." What does it mean? Simply put, we take 21 and double it. [ 2 \times 21 = 42 ]

Can you imagine how easy it is to make a mistake here? What if you'd accidentally multiplied by three instead of two? Yikes! But we're in the clear—42 it is!

  1. Subtracting Seven: Now, our next task is to subtract 7 from 42. So we do that: [ 42 - 7 = 35 ]

Imagine you're looking at your bank account, and you find a charge you didn't expect—subtracting that unexpected cost can feel a little like a math problem, right? Here, we’re just removing the amount due.

  1. Adding Eleven: Up next, we need to add 11 to our last result. Here we go: [ 35 + 11 = 46 ]

Just like that, we’re back on the upswing! You’ve got to love addition—it's like the sweet surprise of chocolate chips in your cookie dough!

  1. Dividing by Two: Finally, we’ll divide this number by two to find Sam's age: [ 46 \div 2 = 23 ]

Voilà! We’ve arrived at Sam’s age: 23. It’s like the grand finale of a fireworks show—everything comes together to make a beautiful ending.

Understand the Process

The beauty of this problem lies in its straightforward structure. Each step builds upon the last, making it incredibly satisfying to see the whole picture unfold. Plus, it’s a great way to warm up those math muscles as you prepare for the Canadian Forces Aptitude Test (CFAT). You know what? Practicing these problems can really help boost your confidence!

Math in Everyday Life

Now, you might be asking yourself, "Where would I ever use this?" It's funny—math is everywhere! From budgeting your grocery shopping to planning your weekend adventures, these simple calculations can guide many of our daily decisions.

And while we’re on the topic of the CFAT, know that understanding expressions like these is key to excelling at the test. Each question you encounter is designed to assess your logical reasoning and problem-solving skills. So the more you practice, the better equipped you’ll be!

Wrapping It All Up

In an age where practice makes perfect, take time to break down complex problems into manageable steps like we did here. You’ve seen how each part of the expression contributes to the greater whole: from overcoming the initial number crunch to triumphantly arriving at Sam's age. Whether you’re studying for your next exam, or simply brushing up on your skills, remember—the journey of learning can be just as rewarding as the answers you find.

Keep practicing, keep exploring, and who knows what you’ll discover next in the world of numbers!
