<h1>Solve Rational Expressions through Onle Calculators</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p>This article mainly tells you the basic concepts of the Rational expressions in mathematics, Use of Probability calculators in solving our statistics and probability problems. The calculator will simplify the expressions by expanding multiplication, combining like terms, and getting the probabilities of the event occurring etc. Now we are going to discuss about Probability. In mathematics, Probability means a way of telling or expressing a given knowledge that an event will occur or has occurred.</p> <p>The Mathematical way to explain the above statement is explained with the help of following equation that an event A occurs , given that an event B is already occurred. P(B|A) = P(A and B) / P(A) P(A/B) = Probability of occurrence of event A when the event B has already occurred and P(B/A) = Probability of occurrence of event B when the event A has already occurred. </p> <p>We can use probability calculator to solve our probability problems. The Probability Calculator calculates the probability of an event, based on probabilities of other related events, that is already occurred. Probability calculator also helps in solving conditional probabilities. In statistics, the probability calculator is basically used to calculate the basic probability problems.</p> <p>Next we are going to understand the basic concepts of rational expressions and how we can solve the problems of rational numbers. Now the first question arises is what is a rational number? Rational number is an expression which can be written as a fraction a/b. Here a is the numerator and b is a denominator. The most important thing to understand is that denominator can never be zero.</p> <p>Following are the closure properties of Rational Number which help in multiplication, addition and division of two rational expressions: Addition x/y + a/b = xb + ay / yb Division a/b divide c/d = ad/bc. Multiplication a/b x c/d = ac/bd. </p> <p>For simplifying rational expressions, we must need to have a good factoring skills. It requires two steps in solving rational expressions. Factoring the numerator and denominator is the first step and the second step is divide all common factors that the numerator and denominator have. Sometimes the Algebra equations come with rational numbers or decimal values, so it is quite difficult to solve such type of equations. Online algebra solvers are available for free which solve algebra problems in just single click or in few seconds and also tell student each and every step used in the problem.</p> </p><strong>About the Author:</strong><br /><p>TutorVista is the #1 portal for learning <a rel="nofollow" href="http://math.tutorvista.com/algebra/rational-expression.html" title="rational expressions">rational expressions</a>.
