DAT (Dental Admission Test) Quantitative Reasoning flashcards — 51 questions with answers

  1. What is the order of operations (PEMDAS) for evaluating arithmetic expressions?

    Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right).

  2. What is the result of dividing any nonzero number by zero, and zero divided by a nonzero number?

    Dividing by zero is undefined; zero divided by any nonzero number equals 0.

  3. How do you add or subtract fractions with different denominators?

    Find a common denominator, convert each fraction to it, then add or subtract the numerators and keep the denominator.

  4. What is the definition of an integer's absolute value?

    Its distance from zero on the number line, always nonnegative: |x| = x if x is greater than or equal to 0, and -x if x is less than 0.

  5. Define prime number and give the smallest prime.

    A whole number greater than 1 with exactly two factors, 1 and itself. The smallest prime is 2 (the only even prime).

  6. What are the divisibility rules for 3 and 9?

    A number is divisible by 3 if its digit sum is divisible by 3; divisible by 9 if its digit sum is divisible by 9.

  7. How do you find the greatest common factor (GCF) and least common multiple (LCM) using prime factorization?

    GCF = product of the lowest powers of common primes; LCM = product of the highest powers of all primes appearing in either number.

  8. What is the difference between rational and irrational numbers?

    Rational numbers can be written as a ratio of two integers (terminating or repeating decimals); irrational numbers cannot (non-repeating, non-terminating decimals like pi or sqrt(2)).

  9. How do you write a number in scientific notation?

    As a x 10^n where 1 is less than or equal to |a| is less than 10 and n is an integer; move the decimal so one nonzero digit is to its left, counting places as the exponent.

  10. When multiplying numbers in scientific notation, what happens to the coefficients and exponents?

    Multiply the coefficients and add the exponents: (a x 10^m)(b x 10^n) = (ab) x 10^(m+n), then normalize the coefficient.

  11. Express 0.00047 in scientific notation.

    4.7 x 10^-4.

  12. What does a negative exponent in scientific notation indicate about the number's magnitude?

    A negative exponent indicates a number less than 1 (a small magnitude); the decimal point moves left |n| places.

  13. How do you solve a linear equation such as 3x + 5 = 20?

    Isolate x: subtract 5 (3x = 15), then divide by 3 (x = 5).

  14. What happens to an inequality when you multiply or divide both sides by a negative number?

    The inequality sign reverses direction (e.g., -2x is less than 6 becomes x is greater than -3).

  15. What is the quadratic formula for ax^2 + bx + c = 0?

    x = [-b plus or minus sqrt(b^2 - 4ac)] / (2a).

  16. What does the discriminant b^2 - 4ac tell you about a quadratic's roots?

    Positive = two distinct real roots; zero = one repeated real root; negative = two complex (no real) roots.

  17. How do you solve a system of two linear equations by substitution?

    Solve one equation for a variable, substitute that expression into the other equation, solve for the remaining variable, then back-substitute.

  18. What are the rules for multiplying and dividing powers with the same base?

    Add exponents when multiplying (x^a · x^b = x^(a+b)); subtract when dividing (x^a / x^b = x^(a-b)).

  19. What is the FOIL method for multiplying two binomials?

    Multiply First, Outer, Inner, Last terms, then combine: (a+b)(c+d) = ac + ad + bc + bd.

  20. State the difference of squares factoring formula.

    a^2 - b^2 = (a + b)(a - b).

Show the other 31 Quantitative Reasoning flashcards

  1. Expand the perfect square binomials (a + b)^2 and (a - b)^2.

    (a + b)^2 = a^2 + 2ab + b^2; (a - b)^2 = a^2 - 2ab + b^2.

  2. What is the slope-intercept form of a line and what does each variable represent?

    y = mx + b, where m is the slope (rise over run) and b is the y-intercept.

  3. How do you calculate the slope between two points (x1, y1) and (x2, y2)?

    m = (y2 - y1) / (x2 - x1).

  4. What defines a function in terms of inputs and outputs?

    A relation where each input (x) maps to exactly one output (y); it passes the vertical line test.

  5. What is the vertex form of a parabola and what does it reveal?

    y = a(x - h)^2 + k, where (h, k) is the vertex; a greater than 0 opens up, a less than 0 opens down.

  6. What is the formula for the area and circumference of a circle?

    Area = pi·r^2; circumference = 2·pi·r (or pi·d).

  7. State the Pythagorean theorem and when it applies.

    a^2 + b^2 = c^2 for a right triangle, where c is the hypotenuse and a, b are the legs.

  8. What is the sum of the interior angles of a triangle and of a quadrilateral?

    Triangle = 180 degrees; quadrilateral = 360 degrees (general polygon = (n-2)·180).

  9. What is the area formula for a triangle and for a trapezoid?

    Triangle = (1/2)·base·height; trapezoid = (1/2)(b1 + b2)·height.

  10. What is the volume formula for a rectangular prism and for a cylinder?

    Rectangular prism = length·width·height; cylinder = pi·r^2·h.

  11. What is the volume formula for a sphere and for a cone?

    Sphere = (4/3)·pi·r^3; cone = (1/3)·pi·r^2·h.

  12. What is the surface area formula for a sphere?

    Surface area = 4·pi·r^2.

  13. Define the three primary trigonometric ratios (SOH-CAH-TOA).

    sin = opposite/hypotenuse; cos = adjacent/hypotenuse; tan = opposite/adjacent.

  14. What are sin, cos, and tan of 30, 45, and 60 degrees?

    sin 30=1/2, cos 30=sqrt(3)/2, tan 30=1/sqrt(3); sin 45=cos 45=sqrt(2)/2, tan 45=1; sin 60=sqrt(3)/2, cos 60=1/2, tan 60=sqrt(3).

  15. State the fundamental Pythagorean trig identity.

    sin^2(x) + cos^2(x) = 1.

  16. What is the difference between mean, median, and mode?

    Mean = arithmetic average (sum/count); median = middle value when ordered; mode = most frequently occurring value.

  17. How does range differ from standard deviation as a measure of spread?

    Range = max minus min (only extremes); standard deviation measures average distance of all data points from the mean.

  18. In a normal distribution, what is the 68-95-99.7 rule?

    About 68% of data lies within 1 standard deviation of the mean, 95% within 2, and 99.7% within 3.

  19. What is the basic probability of an event formula?

    P(event) = number of favorable outcomes / total number of equally likely outcomes.

  20. How do you find the probability of two independent events both occurring?

    Multiply their individual probabilities: P(A and B) = P(A) · P(B).

  21. What is the addition rule for the probability of A or B (mutually exclusive vs not)?

    P(A or B) = P(A) + P(B) for mutually exclusive events; subtract P(A and B) when they can overlap.

  22. How do you read the value of a specific category from a pie chart given the total?

    Multiply the category's percentage (or its angle/360) by the total to get that category's amount.

  23. On a bar graph or histogram, what does the height of each bar represent?

    The frequency, count, or value of the category (bar graph) or class interval (histogram) on the vertical axis.

  24. State the rate-time-distance formula.

    Distance = rate × time (d = rt), so rate = d/t and time = d/r.

  25. If two objects move toward each other, how do you combine their rates?

    Add their speeds to get the closing rate, then use time = distance / combined rate.

  26. What is the work-rate formula for combined work?

    Combined rate = sum of individual rates; if one finishes in a hours and another in b hours, together time = (a·b)/(a+b).

  27. How do you find the concentration of a mixture?

    Concentration = amount of solute / total amount of solution, expressed as a fraction or percent.

  28. How do you convert between units using dimensional analysis?

    Multiply by conversion factors (ratios equal to 1) arranged so unwanted units cancel and desired units remain.

  29. State the simple interest formula.

    I = P·r·t, where P is principal, r is the annual rate (decimal), and t is time in years.

  30. State the compound interest formula.

    A = P(1 + r/n)^(nt), where n is the number of compounding periods per year and A is the final amount.

  31. How do you calculate percent change between an old and new value?

    Percent change = [(new value - old value) / old value] × 100%; positive is increase, negative is decrease.
