We are often asked the difference between expressions and equations and the simple response required is an equal sign. These are mathematical models that help us gauge systems. Rationale expressions are serious tools that help us find solutions to everyday problems. They help us in science and financial immensely. When written carefully they can help us understand modern day phenomenon. We can determine the possible list of solutions and make the best decision based on this. In this section you be asked to evaluate fractional algebraic expressions. In each case a sum or difference operation will be involved. Your goal should be to combine the like terms that you can find first. After that you could just apply basic operations to the whole numbers.

As set of work that gives your students practice with adding and subtracting rational expressions (equations that have fractions containing variables) through factoring, simplifying, and finding the least common denominators. These worksheets explain how to add and subtract rational expressions, but make sure that all of the steps are covered through the list. Use the lesson slowly and make sure that you have understand each step. The overall process will come to as you get the opportunity to continually practice.
