When taking the GED Math test, you should be familiar with arithmetic and math concepts, measurements, equations, and applying math concepts to solve reallife problems.
However, the math test is not a memorization test! You’ll have access to a formula sheet that gives you information like how to calculate the area for different shapes.
You should get familiar with formulas below just to know what to expect.
AREA of a:square  Area = side^{2}  rectangle  Area = length × width  parallelogram  Area = base × height  triangle  Area = ^{1}/_{2} × base × height  trapezoid  Area = ^{1}/_{2} × (base_{1} + base_{2}) × height  circle  Area = p × radius^{2}; p is approximately equal to 3.14. 
PERIMETER of a: square  Perimeter = 4 × side  rectangle  Perimeter = 2 × length + 2 × width  triangle  Perimeter = side_{1} + side_{2} + side_{3} 
CIRCUMFERENCE of a circle  Circumference = p × diameter; p is approximately equal to 3.14. 
VOLUME of a: cube  Volume = edge^{3}  rectangular solid  Volume = length × width × height  square pyramid  Volume = ^{1}/_{3} × (base edge)^{2} × height  cylinder  Volume = p × radius^{2} × height; p is approximately equal to 3.14.  Cone  Volume = ^{1}/_{3} × p × radius^{2} × height; p is approximately equal to 3.14. 
COORDINATE GEOMETRY  distance between points = ; (x_{1}, y_{1}) and (x_{2}, y_{2}) are two points in a plane.slope of a line = ; (x_{1}, y_{1}) and (x_{2}, y_{2}) are two points on the line. 
PYTHAGOREAN RELATIONSHIP  a^{2} + b^{2} = c^{2}; a and b are legs and c the hypotenuse of a right triangle. 
MEASURES OF CENTRAL TENDENCY  mean = , where the x‘s are the values for which a mean is desired, and n is the total number of values for x.median = the middle value of an odd number of ordered scores, and halfway between the two middle values of an even number of ordered scores. 
SIMPLE INTEREST  interest = principal × rate × time  DISTANCE  distance = rate × time  TOTAL COST  total cost = (number of units) × (price per unit) 

You don’t need to memorize everything listed in this guide! You’ll be handed a Math Formula Sheet.
The GED Math test covers content fields like Number Operations and Number Sense (some 20 to 30 percent), Measurement and Geometry (20 to 30 percent), Data Analysis, Statistics, and Probability (20 to 30 percent), and Algebra, Functions, and Patterns (also some 20 to 30 percent).
The GED Math subtest includes two parts. In part two, the use of a calculator is permitted. You are allowed 115 minutes to deal with all the GED Math questions.
