[color=#c51414][b]G[/b]eneral [b]E[/b]ducational [b]D[/b]evelopment[/color] (GED) tests are a group of four subject tests which, when passed, certify that the test taker has American or Canadian high school-level academic skills. Here are some topics which can assist students in learning the mathematics covered on the GED/HiSET/TASC/GCSE [color=#c51414][b]G[/b]eneral [b]C[/b]ertificate of [b]S[/b]econdary [b]E[/b]ducation[/color]. Book 1 is a compilation of basic skills needed for success, but not tested. [b]Mostly PreGED/ABE Skills[/b] Book 2 has many activities which are tested.

Isle of Math

Arithmetic: the branch of mathematics dealing with the properties and manipulation of numbers[br][br]The Isle of Mathematics floats in a Sea of Arithmetic. All special fields of mathematics are dependent on the "Laws of Arithmetic".
Geometry: earth measurements; a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space[br][br]Algebra: the language through which we describe patterns; it allows users to make general rules for arithmetic patterns; saves time for repetative processes[br][br]Trigonometry: a branch of mathematics that studies relationships involving lengths and angles of triangles.[br][br]Analytic Geometry: a branch of algebra that is used to model geometric objects - points, (straight) lines, and circles[br][br]Calculus: the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations[br][br]More advanced chart: [url]http://meta.math.stackexchange.com/questions/6479/a-graph-map-of-math-se[/url]

Percentage Problem

Percentage is one of life's continual problem. Everyone uses them daily, sometimes without knowing it. There are basically 3 unique percentage problems, all are presented here:[br]1) Find the percent of a number. (Usually calculator ready.)[br]2) Find what a number is when you are given the % and the whole.[br]3) Find what percent a number is of another number.[br]The second two require a little algebra to work. Here this algebra has been set to be a proportion which solves easily with all 3 types.
