Summary
This guide covers three types of maths problems that appear in the GRE. It explains how to solve them and gives examples. Students can learn methods to tackle these problems and practice with sample questions.
Defined Functions
Defined functions use a symbol with a specific property. Students learn to solve problems by replacing variables with given values. Examples show how to apply these definitions to find answers.
Number Theory
Number theory involves basic arithmetic properties. Students review key concepts and practice problems. Examples illustrate how to translate word problems into equations and solve them.
Fractions and Proportions
This part explains how to compare and solve fractional equations. It also covers direct and inverse proportions. Examples demonstrate how to set up and solve these types of problems.
Quantitative Comparisons
Quantitative comparisons ask students to compare two quantities. The guide explains methods to solve these problems. Examples show how to avoid common mistakes and find the correct answer.
Key terms
