First of all, you have to make your arithmetic stronger. Almost every individual knows the basic rules of addition, subtraction, multiplication and division. You must learn the advance application of these rules in order to understand them in a more profound way. For instance, you can do word problems to improve your understanding regarding arithmetic. In addition, you must know how to solve the mathematical questions related to exponents, fractions, ratios and other standard operations.
Most of the algebra deals with the problems of equations. Therefore, you should learn the basics of equation solving which is considered as the most important part in algebra. You must learn how to expand products of different numbers and how to simplify a numerical expression. Additionally, learn and practice factorisation of polynomials and placement of fractions over one common denominator. You can make equation solving more easy if you isolate a variable from it or try to simplify one of both sides at a time. Always remember that if you add, subtract, multiply or divide one side of an equation with a number, you will have to do the same with the other side or your answer will be incorrect.
If you are dealing with a word problem related to algebra, you must match your formula with any simple case. It will help you in assessing your solution. Furthermore, never start an exercise before understanding and reviewing the concepts which are given in the book.
One of the most common problems with students is that they think every answer to a problem in algebra will be a whole number. However, it is not the case as the answer can involve decimals, fractions or even be irrational. So, don’t always expect a simple answer and apply the right concepts in finding the solution to a problem.
