The Casio Company created the world's first graphic calculator. Since that time other companies have followed by creating many different versions of the fx-7000G the original graphic calculator. Hewlett Packard known for making many calculators created a number of models in the 90's. The graphic calculator once a handheld instrument was soon to become a part of the notebook genre. Now you can find graphing calculators on the internet with ease and use the system for free.
Many people like the ability to have the program so you can buy your own program and down load to your notebook or computer or perhaps you just prefer the ones that are available for use online. You still can use the handheld models for what purpose you need. The newer models like the current HP 50g (2006 model) because it features a Computer, Algebra System (CAS) capable of manipulating symbolic expressions and analytic solving.

The graphing calculator primarily meant for the professional science/engineering markets is still available for the professional; however, it has been made in a simpler mode to enable the high school and college students to train for the professional world. Texas Instruments produced models that are capable of keeping larger amounts of memory for the professional. Texas Instruments created a graphic calculator that is geared just for the 10-14 year olds in order for a student to start at an early age using the system. It is important to start early using a graphic calculator most educators claim in order to be more proficient when you are older and in a higher grade level.
