30
25
35
Fifteen percent means 15 per hundred, so 15% of 200 is (15/100) × 200 = 30. This method works for any percentage calculation. Converting percentage to a decimal then multiplying helps avoid mistakes. Learn more at .
Simplify the sum: 3/4 + 1/2.
1/4
5/4
7/4
1
Convert 1/2 to quarters (2/4) and add to 3/4 equals 5/4. Converting to a common denominator simplifies addition of fractions. The result can be expressed as an improper fraction or mixed number. For techniques see .
Find the roots of the quadratic equation x² – 5x + 6 = 0.
2 and 3
–2 and –3
–1 and –6
1 and 6
The quadratic factors as (x – 2)(x – 3) = 0, so the solutions are x = 2 or x = 3. Factoring is a quick way to solve when coefficients are integers. Recognizing patterns helps speed up the process. More at .
What is the slope of the line through points (2,3) and (5,11)?
3/8
4/3
8/3
–8/3
Slope is the change in y over change in x: (11–3)/(5–2) = 8/3. This ratio measures steepness of a line. Positive slope indicates an increasing line. For more details visit .
Evaluate 4³ ÷ 2².
1
16
32
4
Compute exponents first: 4³ = 64 and 2² = 4, then divide 64 ÷ 4 = 16. Following exponent rules simplifies the calculation. This applies to any base and exponent. More at .
Find the derivative of f(x) = 3x² + 2x.
6x + 2
6x – 2
6x² + 2
3x + 2
Using the power rule, d/dx[x²] = 2x, so d/dx[3x²] = 6x, and d/dx[2x] = 2. Summing gives 6x + 2. The power rule is foundational in calculus. See for more.
Calculate the perimeter of an equilateral triangle with side length 7.
21
14
7
28
An equilateral triangle has three equal sides. Multiply the side length 7 by 3 to get 21. This formula applies to all equilateral triangles. More at .
Evaluate the definite integral ??³ 2x dx.
18
6
9
3
The antiderivative of 2x is x². Evaluating from 0 to 3 gives 3² – 0² = 9. Definite integrals measure the area under the curve. For details see .
Solve for x: ln(x) = 2.
e²
ln 2
2e
e^(1/2)
Exponentiating both sides with base e gives x = e². Natural logarithms undo exponential functions. Recognizing ln and e relationships is key in calculus. Learn more at .
Find the sum of the infinite geometric series 5 + 3 + 9/5 + … .
15
8
12.5
7.5
The ratio r = 3/5, so the sum is a/(1 – r) = 5/(1 – 0.6) = 12.5. Infinite geometric series converge when |r|<1. This formula is essential for series problems. See .
Solve the system of equations: 2x + y = 7 and x – y = 1.
(3, 1)
(7/3, 4/3)
(5, 2)
(8/3, 5/3)
From x – y = 1, x = y + 1. Substitute into 2(y+1) + y = 7 gives 3y + 2 = 7, so y = 5/3 and x = 8/3. Systematic substitution yields the solution pair. More at .
Evaluate the integral ??^? x·sin(x) dx.
?
2
2?
1
Use integration by parts: let u = x and dv = sin(x)dx, giving uv – ?v du = –x cos(x) + ?cos(x)dx. Evaluating from 0 to ? yields ?. Integration by parts is a key technique in calculus. See .

Cheat Sheet

  1. Master Order of Operations -

    When tackling random math problems, always apply PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) to avoid simple mistakes. This mnemonic, endorsed by Khan Academy, ensures you handle complex expressions correctly every time. Practice with mixed operations to build confidence before timed math tests or a full 100 maths questions and answers drill.

  2. Algebraic Equation Strategies -

    Solving for x in equations and systems is a staple of any mathquiz or random high school math problems set. Use the balance method (adding or subtracting the same term on both sides) and check your answers by substitution. Resources like MIT OpenCourseWare recommend practicing linear, quadratic, and simultaneous equations to see patterns and speed up your workflow.

  3. Key Geometry Formulas -

    Keep essential area and volume formulas at your fingertips: A=πr² for circles, V=ℓ×w×h for prisms, and the Pythagorean theorem a²+b²=c² for right triangles. Drawing quick sketches helps you visualize which formula to apply when facing random math questions on shapes. The University of Cambridge's math department suggests creating flashcards for each formula to reinforce memory.

  4. Essential Trigonometric Identities -

    Remember sin²θ + cos²θ = 1 and the SOH-CAH-TOA mnemonic for sine, cosine, and tangent ratios in triangles. These identities streamline calculations and simplify more complex trigonometric equations on a random math problems quiz. Educational journals highlight that repeatedly writing out identities can embed them in your long-term memory.

  5. Basic Calculus Concepts -

    Familiarize yourself with the power rule (d/dx[x❿]=n·x❿❻¹) for derivatives and the reverse power rule for integrals, as introduced in AP Calculus curricula. Practice differentiating and integrating polynomial functions to build a foundation before tackling advanced questions. According to the American Mathematical Society, systematic practice with small functions accelerates mastery in any math test quiz.
