How do you Simplify Expressions The equations section of QuickMath allows you to solve and plot virtually any equation or system of equations. In most cases, you can find exact solutions to your equations. Even when this is not possible, QuickMath may be able to give you approximate solutions to almost any level of accuracy you... More

How To Solve Equations With Fractions TO SOLVE AN EQUATION WITH fractions, we transform it into an equation without fractions -- which we know how to solve. The technique is called clearing of fractions. Do you start to get nervous when you see fractions? Do you have to stop and review all the rules for adding, subtracting,... More

Solve This Equation This sections illustrates the process of solving equations of various forms. It also shows you how to check your answer three different ways: algebraically, graphically, and using the concept of equivalence. The following table is a partial lists of typical equations. SOLVING LINEAR EQUATIONS Recall the... More

Graph the Line Graphs are easy representation of showing data into the pictorial form. We can show the data representation with the help of several types of graphs. It is because we deal with many types of data so it is obvious to use different types of graph. With the help of graph we can easily understand the problem and find... More

Linear Differential Equations The general representation of Higher Order Linear Differential equations of constant coefficients is yn + an-1 ( x ). yn-1 + an-2 ( x ). yn-2 +… + a0 ( x ). y = g ( x ) (1) The general form of nth order linear differential equation an(x)yn + an-1(x). yn-1 + an-2(x). yn-2 +… + a0(x). Y = g ( x )... More

Multiplying Polynomials A polynomial is the expression which is written in the combination of the different terms joined together with the + or - sign. There can be one or more terms in a polynomial. A polynomial with the one term is called a monomial, a term with two terms is called a binomial and the term with three terms is called... More

Solving Multistep Equations In multi –step equations, we solve the equation in one – step and two steps. When we solve the multi – step equation we have to put the same or like variable in one side of the equal side and the number in other side of the equal sign. Now we see solving multistep equation. For Solving Multistep... More

Statistical Formulas Statistics is used very widely in the mathematics. The statistical approaches are used effectively numerical data. In the statistics we study of gathering data, ordering the data into a proper manner and checking the data line by line. For this we used many formulas. Below is the list of various Statistics...

Find Mean There are other statistical measures that should not be confused with averages - including median and mode . Other simple statistical analyses use measures of spread, such as range, interquartile range, or standard deviation. For a real-valued random variable X, the mean is the expectation of X. Note that not every... More

The Median In statistics and probability theory, median is described as the numerical value separating the higher half of a sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the... More
