The four basic arithmetic operations found in mathematics are: addition, subtraction, multiplication and division. The word “addition” is derived from Latin which means “addition by addition”. The operation of addition consists of two steps i.e., addition of one element with another element. The following examples of this type of operation are: addition of two numbers […]

Simplifying an equation is another way to express solving a mathematical problem. When you simplify an equation, you are basically trying to explain it to the best extent you can. Simply put, if you simplify a simple equation, then both versions of it equal the same value. You can’t really simplify anything because they are

Intercepts and slopes of lines are very important factors that determine the performance of various railroad operations. The main reason for this is that it can affect the efficiency and safety of the railroad. It also plays an important role in the overall operation of the rail lines and the rail systems. This is the

Volume is the amount of three-dimensional dimension enclosed by a solid or closed boundary, such as the area that a solid or shape holds or occupies. Volume is usually measured in cubic metres. A volume of a substance is also commonly described in terms of mass density and/or volume per volume. This article will give

Most likely exam problems on the GRE include independent events. Each independent event either is going to (Yes) occur or will not (No). Once being told how likely a certain event is to occur, then can calculate the likelihood of No by multiplying Yes by the odds against No. To do this process on your

If you are going to take the GRE examination for admission into a graduate program, you must understand that graph of equations is absolutely crucial in getting through the test. So, if you are serious about your application, you must prepare properly for this test. What exactly is a graph of the equation? Well, in

The line graphs are commonly used in different applications, for example, in financial instruments trading. It’s also used for other graph representations. In the graph theory of an undirected graph, the simple line graph G is an undirected (or line) graph that represents the inter-relationships between nodes of G in terms of their inter-bases (or

Circle graphs are a great way to graph musical chords. In fact, they are a type of graph called a directed graph. That is, it’s an undirected graph that has vertices that are related to chords on a line, where two vertices are related if and only if their corresponding chords intersect each other. In

In mathematics, lines are very important. You will need to use them to solve problems and understand shapes and objects. When it comes to solving a math problem, lines and angles are two of the most important mathematical tools. At times, you may be able to add lines, circles, or even circles to a geometrical
