Mastering Basic Math: Understanding the Expression 5 - (3 + 2)

Math can be a bit daunting at times, can’t it? Especially when you’re gearing up for the College Math Placement Test and you encounter expressions that seem tricky at first. But fear not! Today, we’re going to break down the expression 5 - (3 + 2) and reassure you that it’s simpler than it looks.

Let’s Break It Down

You know what? The key to handling these expressions is all about knowing the right order of operations, right? We often remember this through the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). This mnemonic is your best buddy in navigating math problems. Remember, when you see parentheses, tackle them first!

So, let’s apply this to our expression, shall we? We start with the parentheses. What’s 3 + 2? Yep, that’s a solid 5!

Next up, we swap out the parentheses in our original expression:

5 - (3 + 2) becomes 5 - 5.

The Final Step

Now comes the fun part—subtracting! So, let’s compute: 5 - 5 equals 0. That’s right! The result of our expression 5 - (3 + 2) is 0.

Why Is This Important?

Understanding how to navigate math expressions like this is crucial, especially as you prepare for your college placement tests. Grasping these foundational skills makes tackling more complex problems much more manageable.
