Good calculator

what you guys are talking about is completely different than what the point of these calculators are for. Its almost like there are two different kinds of math here.

1. simple addition and subtraction which everyone should be able to do, most of it can even be done in your head such as giving back change as some of you are talking about.

2. Preparation and execution of a calculus or advanced calculus class in which the calculators in this thread are simply tools.

You wouldn't get a graphing calculator to know how much change to give back, that would be like going to the grocery store in a tank (still be cool though). In an advanced class though, even with a calculator in hand like the ones here in this thread, still require a considerable skill. You would still need to have already learned formulas and know what you are doing. A calculator of this caliber is a tool and not a magic box with all the answers.

If anyone has kids going into College algebra, calculus, or advanced calculus then these calculators are highly recommended and that is what the review is for. If anyone knows someone who cant give change back then these calculators wont do them much good and they need extensive tutoring with the basics.

I would be happy to help anyone out if I can.
