Mastering TEAS ATI Mathematics: Simplifying Expressions with Ease

    The world of mathematics might seem daunting at times, especially when it comes to exams specific to nursing school like the TEAS ATI Mathematics Test. But don't sweat it! Simplifying expressions can become second nature with a bit of practice and a clear understanding of the process. So, grab your calculator — well, maybe not just yet — and let’s delve into a sample problem: simplifying the expression \( 14 - (2 + 2 \times 5) \).

Why Order of Operations Matters

You know what’s funny about math? It has rules, and sticking to them makes things way easier. This brings us to the trusty acronym PEMDAS — Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Think of it as the golden rulebook for simplifying expressions.

When posed with ( 14 - (2 + 2 \times 5) ), the first step is to tackle whatever’s inside the parentheses. So, let’s get to work!

Step 1: Operations in Parentheses

Inside our parentheses, there's the expression ( 2 + 2 \times 5 ). Remember PEMDAS? Time to take the multiplication first.

• Start with ( 2 \times 5 ), which equals ( 10 ).

Now, we can bring ( 10 ) back into the parentheses. Adding that to ( 2 ):

• ( 2 + 10 = 12 )

So far, so good! That gives us:

[ 14 - (12) ]

Step 2: Simplify Further

Now, bring down that ( 12 ) and replace our parentheses in the original expression. We now have:

[ 14 - 12 ]

Let’s solve it. You probably guessed it:

[ 14 - 12 = 2 ]

Voilà! The Result

There it is, plain and simple: the result of simplifying ( 14 - (2 + 2 \times 5) ) is ( 2 ). That’s the correct answer (Option A, if you needed the reminder).

Practice Makes Perfect

Want to excel in your TEAS prep? Start with small steps like these. Grab more practice problems that require you to use the order of operations. The more you do, the more comfortable you’ll get. Plus, once you feel confident, you’ll turn that math anxiety into a proud smirk of accomplishment.

As you gear up for the TEAS test, remember that mastering these basics can pave the way for success. With clear strategies, a bit of confidence, and a sprinkle of patience, you’ll soon be tackling even the trickiest math problems with ease. Keep that head high — you’ve got this!
