Algebra is the combination of number theory, mathematical symbols, and geometry focused on understanding and analyzing mathematical symbols. Algebra definition is broad and encompasses different domains of mathematics. The study of Algebra helps in solving basic equations and mathematical problems to complex abstractions. The Algebra questions for CAT are complex, but they can be solved in less time by applying some tricks and algebraic formulae. The problems are complicated, especially with the integration of abstraction of concept, but it can be solved with some basic tricks.
Important Algebra Topics
Algebra is divided into many branches with hundreds of equations and mathematical operations. There are many subbranches of Algebra which open opens to different further complex areas. Here are some of the branches of Algebra topics.
Topic  Explanation 
Elementary Algebra  It is the most basic algebra with a focus on exploring the number systems, arithmetic operations, variables and the use of real numbers. The elementary Algebra questions and solutions mostly include equations, algebraic equations, linear equations, equalities, and inequalities problems etc. 
Advanced Algebra  There are many subparts of Algebra included in the Advanced Algebra. The understanding of conceptions and equations helps in solving Algebra questions and answers for CAT. These are the following topics categorized under Advanced Algebra.  Polynomial Equations and Functions
 Absolute Value Equations, Inequalities and Functions
 Advanced Inequality Equations
 Quadratic Equations & Functions
 Exponential & Logarithmic Functions
 Radical Equations & Functions
 Linear Equations & Solving System
 Matrices
 Discrete Mathematics and Probability

Linear Algebra  This is the branch of Algebra which deals mostly deals with Linear Equations. It helps in defining basic objects in the vector spaces like planes, lines, and rotations. It includes a system of linear equations and matrices and representation along with vector space. The Algebra Study Guides for CAT includes many topics like relations, vector spaces, linear equations, matrices, and computations. 
Abstract Algebra  This subbranch of Algebra majorly deals with the abstract study in a mathematical expression like fields, modules, groups, lattices, vector spaces, lattices etc. There are different types of concepts included in the Abstract Algebra category:  Study of Set and Theorem of Set Theory
 Binary Operations
 Identity and Inverse Elements
 Associativity

When it comes to preparing for the CAT Exam, the Algebra questions and answers mostly are mostly included from topics like Basic Algebra Formulae, Inequalities, Functions, Linear & Quadratic Equations, Logarithms etc.
Tips to Solve Algebra Questions
There are many Algebra tricks and tips which help in solving the questions easily. The understanding and implementation of formulae help in solving.
 Let's take an example of ax^{2} + bx + c = 0. In this a, b and c are constant values and x represents a variable. The power of x is a nonnegative integer in a quadratic equation.
 In linear equations, always use the trick of eliminating the options. For example, if the equation is to find the value of x in the equation, 6x + 5 = 4x 9, use the options in place of x and eliminate the wrong one.
 Know about the formulae and try to apply the formula directly to the value for quick finding of the answers.
