Online math calculator: Calculators are handy tools used to perform calculations easily. Earlier, calculators were electrically powered, and were used only for mathematical calculations. However, the advances in technology have seen the advent of online calculators.

Online calculators work just like their conventional counterparts, with the exception that they are virtual, can be loaded on to your PC, and apart from working out mathematical computations are able to perform other calculations like finding out currency exchange rates, calculating loan rates for mortgages, graphing etc.

The online calculator can be used for almost all math functions, ranging from algebra equations to numerical computations of sequences and series. The scientific calculator accepts brackets, and functions like sin, cos, log etc. Its accessibility, and the free math calculation service it offers, has made the online calculator very popular.

Online Graphing calculators: A graphical calculator is a special kind of scientific/engineering programmable calculator that is able to display a graph and/or analyze it, i.e. explain the graph. They can even show several lines of text and numbers at a time, and some of them even have color displays.

These days, versions that are more modern have added to the family of online calculators for graphing, which are virtual in nature and easy to use. Color is widely used in them to aid in grasping the data easily, and they have 3D plotting, which allow students to understand the graph better.

Most websites that provide math help online usually also have the option of using the online calculator for graphing. However, you can also access these online calculators for free graphing on websites that only provide calculator service. The software used for creating these calculators is usually JAVA.

Free online calculator: One of the best things about these online calculators is that they are free, and you can get an online calculator to calculate almost anything, from the period of ovulation, to knowing the odds of your winning at a poker game.
