Avoid These Common Math Traps on the TEAS Exam
Understand why the wrong answer feels right and how to avoid it.
Hello, future nurses! If you're gearing up for the TEAS exam, you know that math is an essential part of this journey. It's crucial to not only know the right answers but also understand why some wrong answers seem so tempting. Let's explore common pitfalls in TEAS math questions and how you can steer clear of them.
Prime Numbers: The Unsung Heroes
Consider the question: *Which of the following is the smallest prime number?*
Here, it's easy to overlook that the correct answer is 2. Many students mistakenly believe that 1 is a prime number because it's so small and simple, but in reality, a prime number must be greater than 1 and only divisible by 1 and itself. Remembering this rule will keep you on track!
Solving Equations: The Power of Order
Take the equation: *What is the value of x in the equation 3x - 5 = 16?*
The correct answer is 7, but it's easy to slip up if you rush. Start by adding 5 to both sides, resulting in 3x = 21. Divide by 3, and you'll find x = 7. The common mistake here is forgetting to perform each step in order, leading to incorrect answers like 3.67 or 21. Practicing these steps will help reinforce the logical sequence.
Discounts and Sales: Mind the Details
Imagine a sales question: *If a store offers a 25% discount on an item originally priced at $80, what is the sale price?*
The right answer is $60. Often, people incorrectly calculate the discount or subtract it incorrectly. A 25% discount means you subtract 25% of 80 (which is $20) from the original price. It's crucial to keep your calculations clear to avoid mistakes like choosing $64 or $70.
Inequalities: The Rule of Reversal
In the inequality: *Solve 5 - 3x > 2,*
The solution is x < 1. A common pitfall is forgetting to reverse the inequality sign when multiplying or dividing by a negative number. Here, once you subtract 5 from both sides and divide by -3, the inequality changes direction. This reversal is a critical concept to remember.
Triangle Angles: Balancing the Sum
Consider this geometry problem: *In a right triangle, one angle measures 35 degrees. What is the measure of the other acute angle?*
Here, the correct answer is 55 degrees. A triangle's angles must total 180 degrees, and in a right triangle, one angle is always 90 degrees. Thus, the other two angles must add up to 90 degrees. Misunderstanding this can lead to incorrect answers like 35 or 45 degrees.
Order of Operations: PEMDAS is Your Friend
With the operation question: *What is the result of 8 divided by 2 plus 3 times 4 following the order of operations?*
The correct answer is 16. The key is to follow PEMDAS/BODMAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Missteps in this process often lead to answers like 20 or 32, reflecting a common confusion about the order.
Calculating Area: The Square Root Shortcut
Finally, the area question: *If the area of a square is 64 square units, what is the length of one side?*
The answer is 8 units. This is a straightforward application of knowing that the area of a square equals side squared. Taking the square root of 64 gives the side length. Miscalculations can easily lead to incorrect answers like 16 or 4.
Practice Makes Perfect
By understanding these common mistakes and the logic behind each math concept, you're better equipped to tackle your TEAS exam with confidence. Remember, it's not just about knowing the right answers, but also understanding why wrong answers feel right.
