What formulas do I need to know for the TEAS Exam?

The TEAS (Test of Essential Academic Skills) exam covers a variety of subjects, including reading, math, science, English and language usage. Here are some of the formulas and concepts you may need to know for the math section of the exam:

  1. Fractions: addition, subtraction, multiplication, and division
  2. Decimals: addition, subtraction, multiplication, and division
  3. Percentages: conversions, finding percentages of numbers, and percentage increase or decrease
  4. Ratios and proportions
  5. Algebraic equations and expressions: solving for unknowns, factoring, and simplifying expressions.
  6. Geometry: area, perimeter, circumference, and volume of basic shapes (e.g., triangles, rectangles, circles, cubes, and cylinders)
  7. Basic trigonometry: sine, cosine, and tangent functions
  8. Statistics: mean, median, mode, range, and standard deviation
  9. Conversions: metric and imperial units of length, weight, and volume

It is important to note that the exact formulas and concepts covered on the TEAS exam may vary depending on the version of the test you are taking. Be sure to consult the Official TEAS Study Guide or TEAS Online Practice Tests to get a better understanding of what you need to know.

Sample Formulas from the ATI TEAS Study Manual Include:

  1. Distance formula: d = rt (where d is distance, r is rate, and t is time)
  2. Area of a rectangle: A = lw (where A is area, l is length, and w is width)
  3. Perimeter of a square: P = 4s (where P is perimeter, and s is the length of one side)
  4. Volume of a rectangular prism: V = lwh (where V is volume, l is length, w is width, and h is height)
  5. Slope-intercept form of a linear equation: y = mx + b (where m is slope, and b is y-intercept)
  6. Quadratic equation: ax^2 + bx + c = 0 (where a, b, and c are constants and x is the variable)
  7. Pythagorean theorem: a^2 + b^2 = c^2 (where a and b are the lengths of the legs of a right triangle, and c is the length of the hypotenuse)
  8. Circumference of a circle: C = 2πr (where C is circumference, and r is the radius of the circle)
  9. Area of a triangle: A = (1/2)bh (where A is area, b is base, and h is height)
  10. Simple interest formula: I = Prt (where I is interest, P is principal, r is rate, and t is time)
