What is the HESI A2 and the Calculator Policy?
The HESI A2 (Health Education Systems, Inc. Admission Assessment) is an exam used by many nursing and healthcare programs to assess the academic readiness of applicants. It typically covers subjects like Math, Reading Comprehension, Vocabulary, Grammar, Biology, Chemistry, Anatomy & Physiology, and sometimes Physics.
A very common question is: can you use a calculator on HESI A2? For the basic Math Skills section, which tests arithmetic, fractions, decimals, percentages, ratios, and basic algebra, the answer is generally NO. Most schools and testing centers do NOT allow calculators for this part of the exam to assess your fundamental mathematical abilities without aid. However, for sections like Chemistry or Physics (if included), a basic on-screen calculator might be provided by the testing software. It is CRUCIAL to check the specific rules of your testing institution or school before the exam, as policies can vary. Do not assume you can use a calculator on HESI A2 unless explicitly stated for a specific section.
Common misconceptions include believing a calculator is always allowed or never allowed. The reality is it depends on the section and the institution’s rules.
Basic Math Operations on the HESI A2 (and Why Practice Without a Calculator)
The HESI A2 Math section often focuses on your ability to perform calculations manually. This includes:
- Addition, Subtraction, Multiplication, and Division of whole numbers, fractions, and decimals.
- Conversions between fractions, decimals, and percentages.
- Ratios and Proportions.
- Basic Algebra (solving for x).
- Measurement conversions (metric and household).
Since you likely can use a calculator on HESI A2 for the basic math part, practicing these operations without one is vital. Our tool above helps you practice.
| Variable/Operation | Meaning | Unit | Typical Range/Example |
|---|---|---|---|
| Addition (+) | Combining numbers | N/A | 12 + 25 = 37 |
| Subtraction (-) | Finding the difference | N/A | 50 – 18 = 32 |
| Multiplication (×) | Repeated addition | N/A | 7 × 6 = 42 |
| Division (÷) | Splitting into equal parts | N/A | 45 ÷ 9 = 5 |
| Fraction | Part of a whole | N/A | 1/2, 3/4 |
| Decimal | Number with a decimal point | N/A | 0.5, 0.75 |
| Percentage (%) | Part per hundred | % | 50%, 75% |
Practical Examples (Real-World Use Cases)
Here are examples similar to what you might encounter, where you likely can use a calculator on HESI A2 for basic math:
Example 1: Dosage Calculation (Simplified)
A patient needs 250mg of a medication. The medication is available as 100mg per 5ml. How many ml should be administered?
Solution (without a calculator): You need 250mg / 100mg = 2.5 times the amount in 5ml. So, 2.5 × 5ml = 12.5ml.
Example 2: IV Drip Rate (Simplified)
A patient needs 1000ml of fluid over 8 hours. What is the flow rate in ml/hr?
Solution (without a calculator): 1000ml / 8 hours. You can simplify this: 1000/8 = 500/4 = 250/2 = 125 ml/hr.
Practicing these helps even if you can use a calculator on HESI A2 for other sections, as it builds number sense.

Frequently Asked Questions (FAQ)
Q: So, can you use a calculator on HESI A2 math section?
A: Generally, NO, for the basic math skills section. However, some programs might allow a very basic on-screen calculator provided by the test for other sections like Chemistry or Physics, if included. Always verify with your specific testing center or school.
Q: What kind of calculator might be allowed for other HESI A2 sections?
A: If allowed, it’s typically a very basic four-function (add, subtract, multiply, divide) on-screen calculator provided within the testing software. You usually cannot bring your own.
Q: Why are calculators not allowed for the HESI A2 math section?
A: To assess your fundamental mathematical abilities and your ability to perform calculations quickly and accurately without electronic aid, which is important in many healthcare scenarios.
Q: What math topics are covered in the HESI A2 where I can’t use a calculator?
A: Basic arithmetic (whole numbers, fractions, decimals), percentages, ratios, proportions, basic algebra, and measurement conversions.
Q: How should I prepare for the HESI A2 math section if I can’t use a calculator?
A: Practice, practice, practice doing math by hand and mentally. Use practice tests and workbooks specifically designed for the HESI A2 math section without a calculator.
Q: Are there any exceptions to the “no calculator” rule for the math section?
A: While rare for the basic math section, only your specific testing institution can confirm any exceptions or accommodations. Don’t assume you can use a calculator on HESI A2 unless officially informed.
Q: What if I have a documented disability that requires a calculator?
A: You would need to contact the testing institution or your school well in advance to request accommodations based on documented needs. They will have a specific process for this.
Q: Is knowing I can use a calculator on HESI A2 for some sections but not others important?
A: Yes, it’s vital. You need to prepare to do basic math without one and be ready to use the provided one (if any) for other sections efficiently.
