HiSET® Math Formula Sheet

Keep this handy while you practice. A formula sheet is also provided on the real HiSET® exam.

Area & Perimeter

  • RectangleArea = l × w
  • RectanglePerimeter = 2l + 2w
  • TriangleArea = ½ b h
  • ParallelogramArea = b h
  • TrapezoidArea = ½(b1 + b2)h
  • CircleArea = πr2
  • CircleCircumference = 2πr

Volume & Surface Area

  • Rectangular prismV = l w h
  • Prism (surface)SA = 2(lw + lh + wh)
  • CylinderV = πr2h
  • Cylinder (surface)SA = 2πr2 + 2πrh
  • ConeV = ⅓πr2h
  • PyramidV = ⅓ (base area) h
  • SphereV = ⁴⁄₃ πr3
  • Sphere (surface)SA = 4πr2

Algebra & Coordinate Geometry

  • Slopem = (y2 − y1) ÷ (x2 − x1)
  • Slope–intercepty = mx + b
  • Point–slopey − y1 = m(x − x1)
  • Distanced = √[(x2−x1)2 + (y2−y1)2]
  • Quadratic formula ★x = (−b ± √(b2−4ac)) ÷ 2a

Right Triangles & Rates

  • Pythagorean theorem ★a2 + b2 = c2
  • Distance–rate–time ★d = r × t
  • Simple interestI = p r t

Statistics & Probability

Answers:

1- E
Simplify:
\(4(x + 1) = 6(x − 4) + 20\)
\(4x + 4 = 6x − 24 + 20\)
\(4x + 4 = 6x – 4\)
Subtract \(4x\) from both sides:
\(4 = 2x – 4\)
Add 4 to both sides:
\(8 = 2x\)
\(4 = x\)

2- E
\(2.5\%\) of \(1,200 = 0.025 × 1200 = 30\)

3- E
Use FOIL (First, Out, In, Last)
\((2x + 2y)(5x + 2y) = 10x^2+ 4xy + 10xy + 2y^2 = 10x^2+ 14xy + 4y^2\)

4- E
Use distributive property:
\(2x (4 + 2y) = 8x + 4xy = 4xy+ 8x\)

5- E
\(y = 4ab + 3b³\)
Plug in the values of a and b in the equation: \(a = 2 \)and \(b = 3\)
\(y = 4 (2) (3) + 3 (3)3 = 24 + 3(27) = 24 + 81 = 105\)

6- C
\(11 × 36 + 6 × 12 + 4 = 472\)

7- D
Let \(x\) be the integer. Then:
\(2x – 5 = 83\)
Add 5 both sides: \(2x = 88\)
Divide both sides by \(2: x = 44\)

8- D
To find the discount, multiply the number by \((100\% – rate of discount)\).
Therefore, for the first discount we get: \((200) (100\% – 15\%) = (200) (0.85) = 170\)
For the next \(15 \%\) discount: \((200) (0.85) (0.85)\)

9- B
Plug in each pair of number in the equation:
A. \((2, 1): 2 (2) + 4 (1) = 8\)
B. \((–1, 3): 2 (–1) + 4 (3) = 10\)
C. \((–2, 2): 2 (–2) + 4 (2) = 4\)
D. \((2, 2): 2 (2) + 4 (2) = 12\)

10- E
Use PEMDAS (order of operation):
\(5 + 8 × (–2) – [4 + 22 ×5] ÷ 6 = 5 + 8 × (–2) – [4 + 110] ÷ 6 = 5 + 8 × (–2) – [114] ÷ 6 = 5 + (–16) – 19 = 5 + (–16) – 19 = –11 – 19 = –30\)

11- B
Use this formula: Percent of Change
\(\frac{New \space Value-Old \space Value}{Old \space Value}× 100 \%\)
\(\frac{16000-20000}{20000}× 100 \% = 20 \%\)
and
\(\frac{12800-16000}{16000}× 100 \% = 20 \%\)

12- D
If the length of the box is 27, then the width of the box is one third of it, 9, and the height of the box is 3 (one third of the width). The volume of the box is:
\(V = lwh = (27) (9) (3) = 729\)

13- D
Write the equation and solve for B:
\(0.60 A = 0.20 B\), divide both sides by 0.20, then you will have \(0.60/0.20 A = B\), therefore:
\(B = 3\) A, and B is 3 times of A or it’s \(300\%\) of A.

14- E
To find the number of possible outfit combinations, multiply number of options for each factor:
\(6 × 3 × 5 = 90\)

15- D
The relationship among all sides of special right triangle
30\(^\circ\)-60\(^\circ\)- 90\(^\circ\) is provided in this triangle:

In this triangle, the opposite side of 30\(^\circ\) angle is half of the hypotenuse.
Draw the shape of this question:
The latter is the hypotenuse. Therefore, the latter is 60 ft

16- E
\(g(x)=-2, then f(g(x))= f(-2)=2 (-2)^3+5(-2)^2+2(-2)= -16+20-4=0\)

17- E
Let \(x\) be the width of the rectangle. Use Pythagorean Theorem:
\(a^2 + b^2 = c^2\)
\(x^2 + 8^2 = 10^2 ⇒ x^2 + 64 = 100 ⇒ x^2 = 100 – 64 = 36 ⇒ x = 6\)
Perimeter of the rectangle \(= 2 (length + width) = 2 (8 + 6) = 2 (14) = 28\)

18- B
The perimeter of the trapezoid is 36.
Therefore, the missing side (height) is \(= 36 – 8 – 12 – 6 = 10\)
Area of a trapezoid: \(A = \frac{1}{2}h (b_{1} + b_{2}) = \frac{1}{2} (10) (6 + 8) = 70\)

19- B
The probability of choosing a Hearts is \(13/52 = 1/4\)

20- D
Change the numbers to decimal and then compare.
\(\frac{2}{3}= 0.666…\)
0.68
\(67% = 0.67\)
\(\frac{4}{5} = 0.80\)

Frequently Asked Questions

How many questions are on the HiSET Math test?

50 multiple-choice questions. The content split is roughly 19% numbers and operations, 28% algebra, 18% geometry, and 35% data analysis/statistics/probability. Time limit is 90 minutes.

Is a calculator allowed on HiSET Math?

Yes. On computer-based HiSET, an on-screen TI-30XS scientific calculator is available throughout the math subtest. On paper-based HiSET, you bring your own approved non-graphing scientific calculator from the official approved list.

Is there a formula sheet on the HiSET?

Yes. Every HiSET Math administration includes a formula reference page covering area, perimeter, volume, the Pythagorean theorem, simple interest, slope, and the distance formula. The quadratic formula and trig identities are NOT on the sheet.

What score do I need to pass HiSET Math?

A subtest score of 8 (on the 1-20 scale) is the typical minimum for math. You also need a total of 45 across all five subtests with no subtest below 8, plus at least 2 out of 6 on the writing essay. Some states require higher minimums.

How long is the HiSET Math test?

90 minutes for 50 questions, so about 1 minute 48 seconds per question on average. Most testers finish with a few minutes to spare. The on-screen calculator can chew up time if you’re not familiar with the TI-30XS — practice with one before test day.

Is HiSET easier than the GED?

The HiSET gives you a formula sheet and a longer time-per-question, so many adult learners find it more forgiving. The GED is shorter (115 minutes for 46 questions) but denser. Test content is roughly comparable.

Can I retake just the HiSET Math subtest?

Yes. HiSET allows you to retake individual subtests. Most states allow up to 3 attempts per subject per year. Your passing scores on other subtests carry over.

Is HiSET computer-based or paper-based?

Both. Computer-based HiSET is offered at PSI test centers and includes the on-screen TI-30XS. Paper-based HiSET is offered at many adult learning centers. Content and scoring are identical between the two formats.

How long should I study for the HiSET Math test?

Most adult learners need 6 to 12 weeks of consistent study at 30-60 minutes per day to go from rusty to ready. Start with a full-length practice test as your diagnostic, then target your weakest content area.

Where do I get HiSET Math answer explanations?

Detailed answer explanations for this practice test live on the linked Answers and Explanations page (math-topics/full-length-hiset-math-practice-test-answers-and-explanations). Each explanation walks through the step-by-step math behind every correct choice.
