covering the math portion of the ged test introduction to math portion of ged site layout i’ve updated the site to reflect the new version of the ged math test and organized it based on the assessment content indicators that the developers of the ged designed the test around. to be sure every aspect of the math portion of the test is covered here, there is roughly one page on this site for each content indicator. you can use the table below and work through each topic on the test or navigate or search to any trouble area you may have. below this table i go over the ged math question types, the formula sheet and the calculator. q.1 apply number sense concepts, including ordering rational numbers, absolute value, multiples, factors, and exponents q.1.a order fractions and decimals, including on a number line. q.1.b apply number properties involving multiples and factors, such as using the least common multiple, greatest common factor, or distributive property to rewrite numerical expressions. q.1.c apply rules of exponents in numerical expressions with rational exponents to write equivalent expressions with rational exponents. q.1.d identify absolute value or a rational number as its distance from 0 on the number line and determine the distance between two rational numbers on the number line, including using the absolute value of their difference. q.2 add, subtract, multiply, divide, and use exponents and roots of rational, fraction and decimal numbers q.2.a perform addition, subtraction, multiplication, and division on rational numbers. q.2.b perform computations and write numerical expressions with squares and square roots of positive, rational numbers. q.2.c perform computations and write numerical expressions with cubes and cube roots of rational numbers. q.2.d determine when a numerical expression is undefined. q.2.e solve one-step or multi-step arithmetic, real world problems involving the four operations with rational numbers, including those involving scientific notation. q.3 calculate and use ratios, percents and scale factors q.3.a compute unit rates. examples include but are not limited to: unit pricing, constant speed, persons per square mile, btus per cubic foot. q.3.b use scale factors to determine the magnitude of a size change. convert between actual drawings and scale drawings. q.3.c solve multistep, arithmetic, real-world problems using ratios or proportions including those that require converting units of measure. q.3.d solve two-step, arithmetic, real world problems involving percents. examples include but are not limited to: simple interest, tax, markups and markdowns, gratuities and commissions, percent increase and decrease. q.4 calculate dimensions, perimeter, circumference, and area of two-dimensional figures q.4.a compute the area and perimeter of triangles and rectangles. determine side lengths of triangles and rectangles when given area or perimeter. q.4.b compute the area and circumference of circles. determine the radius or diameter when given area or circumference. q.4.c compute the perimeter of a polygon. given a geometric formula, compute the area of a polygon. determine side lengths of the figure when given the perimeter or area. q.4.d compute perimeter and area of 2-d composite geometric figures, which could include circles, given geometric formulas as needed. q.4.e use the pythagorean theorem to determine unknown side lengths in a right triangle. q.5 calculate dimensions, surface area, and volume of three-dimensional figures q.5.a when given geometric formulas, compute volume and surface area of rectangular prisms. solve for side lengths or height, when given volume or surface area. q.5.b when given geometric formulas, compute volume and surface area of cylinders. solve for height, radius, or diameter when given volume or surface area. q.5.c when given geometric formulas, compute volume and surface area of right prisms. solve for side lengths or height, when given volume or surface area. q.5.d when given geometric formulas, compute volume and surface area of right pyramids and cones. solve for side lengths, height, radius, or diameter when given volume or surfacearea. q.5.e when given geometric formulas, compute volume and surface area of spheres. solve for radius or diameter when given the surface area. q.5.f compute surface area and volume of composite 3-d geometric figures, given geometric formulas as needed. q.6 interpret and create data displays q.6.a represent, display, and interpret categorical data in bar graps or circle graphs. q.6.b represent, display, and interpret data involving one variable plots on the real number line including dot plots, hitograms, and box plots. q.6.c represent, display, and interpret data involving two variables in tables and the coordinate plane including scatter plots and graphs. q.7 calculate and use mean, median, mode and weighted average q.7.a calculate the mean, median, mode and range. calculate a missing data value, given the average and all the missing data values but one, as well as calculating the average, given the frequency of counts of all the data values, and calculating a weighted average. q.8 utilize counting techniques and determine probabilities q.8.a use counting techniques to solve problems and determine combinations and permutations. q.8.b determine the probability of simple and compound events. a.1 write, evaluate, and compute with expressions and polynomials a.1.a add, subtract, factor, multiply and expand linear expressions with rational coefficients. a.1.b evaluate linear expressions by substituting integers for unknown quantities. a.1.c write linear expressions as part of word-to-symbol translations or to represent common settings. a.1.d add, subtract, mulitiply polynomials, including miltiplying two binomials, or di
