How It Works
Time Saved = (Manual Time per Problem – Calculator Time per Problem) * Number of Problems
This calculation estimates the total seconds saved by using the on-screen calculator compared to solving each math problem manually. We then compare this to your total exam time to see the impact.
Assumptions: This calculator assumes that all math problems can be solved using the basic on-screen calculator and that your estimated times are accurate.
HESI A2 Math Section Overview
The HESI A2 exam includes a Math section designed to assess your foundational mathematical skills necessary for healthcare professions. This section typically covers topics such as:
- Basic Math Skills: Addition, subtraction, multiplication, division.
- Fractions, Decimals, and Percentages: Converting between them, performing operations.
- Ratios and Proportions: Understanding and applying these concepts.
- Algebraic Concepts: Solving basic equations, working with variables.
- Dimensional Analysis: Converting units using conversion factors, essential for dosage calculations.
- Basic Stats: Mean, median, mode.
While the exam does *not* allow personal calculators, it *does* provide a basic on-screen calculator. This calculator typically includes functions for addition, subtraction, multiplication, division, square root, and percentage. Knowing how to use this tool efficiently can be beneficial, especially for dosage calculation problems.
HESI A2 Calculator Policy: What You Need to Know
Can I use a calculator on the HESI A2 exam? The official policy is that candidates are **provided with a basic, on-screen calculator** by the testing software. You are **not permitted to bring your own calculator** of any type, whether it’s a scientific, graphing, or basic handheld calculator.
This means you must rely solely on the digital calculator provided within the HESI A2 testing interface. Familiarizing yourself with the functionality of standard on-screen calculators during your preparation is highly recommended.
Why the Restriction? The HESI A2 math section is designed to test your fundamental math abilities, including your capacity to perform calculations quickly and accurately, often using techniques like dimensional analysis where complex calculator functions aren’t the primary focus. The provided on-screen calculator is intended to assist with arithmetic operations, not to replace core understanding.
Practical Examples
Example 1: Dosage Calculation Practice
Scenario: A physician orders 500 mg of a medication. The available stock is 250 mg per tablet. How many tablets should be administered?
Inputs for Calculator:
- Number of Math Problems: 1 (focusing on this one calculation)
- Avg. Manual Solve Time (sec/problem): 75 seconds (requires calculation: 500mg / 250mg/tablet)
- Avg. Calculator Solve Time (sec/problem): 30 seconds (using on-screen calculator: 500 / 250)
- Total Exam Time (minutes): 300 minutes
Calculation Results:
- Potential Time Saved: 45 seconds
- Total Manual Time: 75 seconds
- Total Calculator Time: 30 seconds
- Estimated Time Saved (Minutes): 0.75 minutes
- Percentage of Exam Time Saved: 0.25%
Interpretation: Even for a single dosage calculation, using the on-screen calculator can save a significant amount of time compared to performing the division manually. Multiplied over several dosage problems, this saving becomes more substantial.
Example 2: Ratio and Proportion Problem
Scenario: A patient needs 2 L of IV fluid over 8 hours. At a rate of 20 drops/mL, what is the drip rate in mL/hr?
Inputs for Calculator:
- Number of Math Problems: 1
- Avg. Manual Solve Time (sec/problem): 120 seconds (requires multiple steps: Volume/Time, then Volume*Factor)
- Avg. Calculator Solve Time (sec/problem): 60 seconds (using on-screen calculator: 2000mL / 8hr = 250 mL/hr)
- Total Exam Time (minutes): 300 minutes
Calculation Results:
- Potential Time Saved: 60 seconds
- Total Manual Time: 120 seconds
- Total Calculator Time: 60 seconds
- Estimated Time Saved (Minutes): 1 minute
- Percentage of Exam Time Saved: 0.33%
Interpretation: This example highlights how problems requiring conversions or multiple steps can benefit significantly from calculator use. Efficiently navigating the on-screen calculator can free up time for more complex questions or reviewing answers.

Key Factors Affecting HESI A2 Math Performance
- Familiarity with Concepts: A deep understanding of fractions, decimals, percentages, ratios, and basic algebra is paramount. Without conceptual clarity, even a calculator is of limited use.
- Dimensional Analysis Proficiency: Many HESI A2 problems, especially dosage calculations, rely on dimensional analysis. Mastering this technique allows for accurate unit conversions and reduces reliance on rote memorization of formulas.
- Calculation Speed: Both manual and calculator-assisted speed matter. Practice improves both. The on-screen calculator is faster than manual calculation for complex arithmetic, but quick mental math for simple operations is also valuable.
- Time Management Skills: The HESI A2 has strict time limits. Allocating appropriate time per question and recognizing when to use the calculator versus performing quick mental math is crucial.
- Understanding the On-Screen Calculator: Knowing exactly which functions are available (basic arithmetic, percentage, square root) and how to operate them quickly prevents fumbling during the timed exam.
- Test Anxiety: Nervousness can impair concentration and calculation ability. Practicing under timed conditions and using relaxation techniques can help mitigate this.
- Question Complexity: Some HESI A2 math problems are straightforward arithmetic, while others involve multiple steps or conceptual understanding. The time saved by a calculator varies significantly based on this complexity.
- Accuracy: While speed is important, accuracy is critical. Double-checking calculations, whether manual or with a calculator, ensures correct answers.
