The HESI A2 entrance exam is a big deal for anyone looking to get into nursing or healthcare. Among the many sections, the math portion can seem like a breeze, until you realize it’s not just about simple calculations. One of the core areas is arithmetic, specifically addition and subtraction. It sounds easy enough, but when you’re under time pressure and can’t skip questions, even the basics can trip you up. Let’s break down what you need to know about addition and subtraction for the HESI A2 math section.
Why Addition and Subtraction Matter in the HESI A2 Math Section
Addition and subtraction are the foundation of arithmetic, and they’re used in a wide range of scenarios in healthcare. Whether you’re calculating medication dosages, adjusting IV drip rates, or managing patient records, you need to be spot-on with your calculations. On the HESI A2 math section, these operations can appear in various forms, so let’s talk about what you might encounter.
Types of Addition and Subtraction Problems on the HESI A2 Math Section
Here’s what you might face when it comes to addition and subtraction on the HESI A2 math section:
- Basic Addition and Subtraction: This involves straightforward calculations. You might need to add or subtract single-digit or multi-digit numbers, and you might encounter word problems that require basic arithmetic.
- Working with Fractions: Addition and subtraction can get tricky when fractions are involved. You need to find a common denominator before you can add or subtract the numerators.
- Handling Decimals: Addition and subtraction with decimals require careful alignment of decimal points. If you’re off by one place, it can throw off the entire answer.
- Solving Word Problems: These problems require you to read a scenario and determine which operations to use. They often involve addition and subtraction in real-world contexts.
Tips for Solving Addition and Subtraction Problems on the HESI A2 Math Section
Addition and subtraction might seem straightforward, but a little practice goes a long way. Here are some tips to help you tackle these problems on the HESI A2 math section:
1. Align the Numbers Correctly
When adding or subtracting multi-digit numbers or decimals, alignment is key. Make sure the decimal points line up, and the digits are properly aligned in their place values. This simple step can prevent a lot of mistakes.
2. Use Scratch Paper/White Board (if your test center allows)
Scratch paper/white board is a lifesaver when solving addition and subtraction problems. Use it to write out calculations, especially when working with fractions or decimals. It helps you keep track of your work and catch errors.
3. Find Common Denominators for Fractions
If you’re adding or subtracting fractions, you need a common denominator. Find the least common multiple of the denominators and then adjust the fractions accordingly. Once you have a common denominator, you can add or subtract the numerators.
4. Break Down Word Problems
Word problems can be tricky because they require you to identify the operations to use. Break down the problem into smaller steps, and look for keywords that indicate addition or subtraction. Words like “total,” “combine,” and “increase” suggest addition, while “difference,” “decrease,” and “reduce” suggest subtraction.
5. Double-Check Your Work
Always double-check your work, especially when adding or subtracting multi-digit numbers or working with fractions and decimals. A simple misalignment can lead to a wrong answer, so take a moment to review your calculations before submitting your answer.
