Sample HESI A2 Math Practice Questions

Try these sample questions to review concepts for the HESI A2 Math exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is 24 + 36 ÷ 4 × 2 − 5?
A.37
B.27
C.19
D.33
Explanation: Use order of operations (PEMDAS). First, division and multiplication left to right: 36 ÷ 4 = 9, then 9 × 2 = 18. Then addition and subtraction left to right: 24 + 18 = 42, then 42 − 5 = 37.
2Solve: (8 + 2) × 3 − 4²
A.14
B.16
C.22
D.10
Explanation: Apply PEMDAS. Parentheses first: 8 + 2 = 10. Exponent next: 4² = 16. Multiplication: 10 × 3 = 30. Subtraction last: 30 − 16 = 14.
3What is 1,248 − 379?
A.869
B.879
C.969
D.859
Explanation: Subtract place by place with borrowing: 1248 − 379. 8 − 9 requires borrowing (18 − 9 = 9). Then 3 − 7 with borrow (13 − 7 = 6, after the prior borrow gives 8). Continue to get 869.
4What is 47 × 23?
A.1,081
B.1,071
C.1,181
D.961
Explanation: Use long multiplication. 47 × 3 = 141. 47 × 20 = 940. Add: 141 + 940 = 1,081.
5What is 504 ÷ 12?
A.42
B.44
C.48
D.40
Explanation: Divide step by step. 12 × 40 = 480. Remainder is 504 − 480 = 24. 24 ÷ 12 = 2. Total quotient is 40 + 2 = 42.
6Evaluate: 6 + 2 × (10 − 4) ÷ 3
A.10
B.8
C.14
D.6
Explanation: Parentheses first: 10 − 4 = 6. Then multiplication and division left to right: 2 × 6 = 12, then 12 ÷ 3 = 4. Finally addition: 6 + 4 = 10.
7Add: 1/4 + 2/3
A.11/12
B.3/7
C.3/12
D.5/7
Explanation: Find a common denominator of 12. 1/4 = 3/12 and 2/3 = 8/12. Add the numerators: 3/12 + 8/12 = 11/12. The result is already in simplest form.
8Subtract: 5/6 − 1/4
A.7/12
B.4/2
C.1/2
D.2/3
Explanation: Find a common denominator of 12. 5/6 = 10/12 and 1/4 = 3/12. Subtract: 10/12 − 3/12 = 7/12. This is already in lowest terms.
9Multiply: 2/5 × 3/8
A.3/20
B.6/13
C.5/13
D.5/40
Explanation: Multiply numerators and denominators: (2 × 3)/(5 × 8) = 6/40. Simplify by dividing top and bottom by 2 to get 3/20.
10Divide: 3/4 ÷ 2/3
A.9/8
B.1/2
C.6/12
D.8/9
Explanation: To divide fractions, multiply by the reciprocal: 3/4 × 3/2 = 9/8. As a mixed number this is 1 1/8.

Frequently Asked Questions

How many questions are on the HESI A2 Mathematics section?

The HESI A2 Math subtest has 55 multiple-choice items: 50 scored items and 5 unscored pilot items. Elsevier's recommended time is 50 minutes, according to its item table as restated by schools such as Quincy College and Tarrant County College.

Can I use a calculator on the HESI A2 Math section?

Yes. An on-screen calculator is provided, and personal calculators are not allowed. Elsevier does not publish a key-by-key description, so do multiplication and division first and write intermediate results on scratch paper.

What math topics are on the HESI A2 Math exam?

Elsevier says the subtest focuses on math skills needed for health care, including basic addition, subtraction and multiplication, fractions, decimals, ratio and proportion, household measures and general math facts. Reviews also cover percentages, metric conversions, temperature, Roman numerals, military time and basic algebra.

What is considered a passing score for HESI A2 Math?

Elsevier does not set a passing score; each program sets its own. For example, South Texas College requires 75% or higher on each section, and Hannibal-LaGrange University requires at least 80% in Math.

How much time is allotted for the HESI A2 Math section?

Elsevier's recommended time is 50 minutes for 55 items, about 55 seconds per item. Many schools set one total time for all required sections instead, such as 4 or 4.5 hours.

Are dosage calculation formulas provided during the test?

Plan to memorize them. Elsevier and school test-day materials do not mention a formula or conversion sheet, so learn conversions such as 1 teaspoon = 5 mL and 1 kilogram = 2.2 pounds, plus the temperature formulas.
