What do I do with this thing now?
You can do a number of very complex mathematical tasks on a scientific calculator, performing everything from Statistics and Geometry to mortgages and gaming. If you are considering the purchase of a scientific calculator, consider not only your current needs but also how you might use the calculator in the future. Consider that some models, like graphing and engineering calculators, can cost as much as $200.
Saving money
If portability is not an issue, buying an expensive handheld calculator may not be the most prudent way to go. There is software available that emulates the functionality of a scientific calculator. There is also palm computer software that does the same while consolidating a closet full of gadgets into one integrated device.
If the calculator is for a student though you should know that a palm computer with special software will not be an acceptable alternative because of concerns about connectivity and cheating. Most PDAs (Personal Digital Assistants) have wireless technology that gives users the ability to share answers during tests.
Using your calc beyond the classroom
One aspect of scientific calculators that should also be considered is the ease with which your device can be programmed. This is why it is important to have an up to date model with a USB port that will allow the device to download software from another computer. For models offered by TI or HP one can join a website like FreeMathHelp.com or TIcalc.com which offer software for free that can greatly increase the functionality of your calculator. There are even games such as Tetris that are available on these sites.
This may be a double-edged sword when considering a calculator for a High School student. Most of the thousands of downloads are games that have an educational component. The gaming aspect of the device might seem frivolous but it does make useful a $200 calculator that might go unused if your student decides to major in History. A calculator like this and the programming subculture that surrounds it could just as likely lead your student into the lucrative business of computer programming.
Another great feature is the utilitarian programs available for free that assist in calculating financial matters. You can figure the amortization schedule of a home loan that can help you figure out when exactly there will no longer be interest payments to write off on your taxes. There are also programs that show you the future value of an investment. This can not only allow you to see the value of compounding, but also help you see what approach would make the best bottom line sense for you and your family.
