Chapter 16: Quantitative Comparisons Quantitative Comparison questions include two mathematical expressions, usually following a question stem which applies to both expressions (quantity A and quantity B). · You usually don’t need to calculate a specific answer, just determine which is greater, whether they are equal, or if you need more information · Memorize these answer choices! · Do not rely on the calculator – avoid unnecessary computations · Be very careful with geometric figures, as they are not necessarily drawn to scale · The last answer choice D should ONLY be selected if no computation is possible OR if you can generate multiple different relationships (e.g., A is greater if x > 2, but A is lesser if x = 2) · Always simplify the expressions ...
The GRE Exam The GRE has three primary measures. Analytical Writing 2 essays - 30 minutes each Focus on the skill of directly responding to the presented tasks Math (Quantitative Reasoning) 2 sections of 20 questions each - 35 minutes each Focus on basic math concepts & skills Verbal 2 sections of 20 questions each - 30 minutes each Focus on reading & reasoning skills (no other official sections) 1 minute break between all sections except for a 10 minute break after section 3 Labeled research section possible; unlabeled experimental section possible • Onscreen calculator during Quantitative sections (reduces emphasis on computation, increases emphasis on logic) • You can change/edit/review answers, i.e. “Mark & Review” f...
Chapter 12: Math Foundations – Algebra Review Memorize: · Algebraic terms o Variable – letters representing unknown quantities o Constants – numbers not multiplied by any variable o Terms – constants and products of constants and variables o Product – result of multiplication o Coefficient – the constant in front of a variable; if no number is visible, the coefficient is understood to be 1 o Algebraic expression – any mathematical expression (‘sentence’) containing one or more constants, variables, and possibly one or more operation symbols (e.g., +- etc.) o Monomial – algebraic expressions with a single term (no spaces or operators, e.g., 2, 3a, 4xyz, etc.) o Polynomial – algebraic expressions with more than one term (combined with operators and spaces, e.g., 2 + 3a, etc.) § Binomial – has exactly two terms § ...
