Review of Ti-nspire Cas Software-teacher

Average Reviews:

(More customer reviews)The TI-Nspire CAS is an improved version of theTI-89 calculator. Like the TI-89 it has graphing and symbolic capability as well as the usual calculator functions.What is new in this calculator over the TI-89?The features that I have been able to identify and use are a definite improvement.One feature is that there are templates for most of the operations needed in calculus.These include integration, differentiation, limit, product, and others.The templates make it less likely that there are syntax errors in entering a calculation.The templates can also be used in programs as well as doing individual calculations.

It is possible to organize problems and documents on the TI-Nspire CAS.You can save work as documents.The documents have pages to organize the work into logical divisions.Your work can be saved and retrieved in an organized way.It is also possible to have more than one window displayed at a time.By this means you can monitor a graph as a parameter is changed or you can immediately see the effect of changing some part of a program.

The software version of the TI-Nspire CAS calculator is invaluable for those using the calculator in the classroom.Now you can bring a laptop to class with the software installed.By connecting the laptop to a projector, you can now teach the use of the calculator very effectively.The display is more detailed than projecting the calculator display.With the software version is also easier to write programs and do calculations since you have the computer keyboard and mouse.

Are there drawbacks?The TI-Nspire CAS is definitely intimidating.Once you have learned to navigate its many features, it is very powerful.However, without help, you will have trouble seeing how to do even some of the simple things that you may have in mind.As the calculator becomes more popular, this will not be the problem that it is now.Now, there is no one to turn to when you are frustrated.

As an example, I created some functions.They were examples to see how to create the functions and use them.When I was finished I wanted to delete them.But how do I delete them?Being familiar with the TI-89, I thought that the process would be similar.The familiar ways in the TI-89 did not work on the TI-Nspire CAS.Now that I have figured it out, it is simple enough.But finding the solution to this and other problems can be frustrating for the beginner.A human guide would be helpful and for most people essential.

How does the software compare with Maple and Mathematica?The TI-Nspire CAS software is limited, but has enough capability to be useful for classroom use.

Review of Sharp QS2760H 2-Color Ribbon Printer

Average Reviews:

(More customer reviews)I am a CPA who depends on calculators.We have several of this model in our office, and have used similar Sharp machines for years.We have found them reliable, easy to use, durable machines, and feel the price is reasonable for the quality of the machine.They do need replaced every 4 to 5 years, but by then we feel we have received our value from them, and have always replaced them with a Sharp machine identical or with very similar features to this one.

Review of 8 Digit Display Large Key Jumbo Calculator

Average Reviews:

(More customer reviews)The buttons on this calculator are soft/grippy rubber, which makes them difficult to work given their size (the area you have to press is directly in the center of the key and takes quite a push to make work.You definitely can't 10-key this thing without looking carefully to make sure each keypress is registered.Further, after only one day of use, the kids managed to drop it from about desk height onto the floor (which has been done with just about ever thing on my desk a time or two!) and the calculator stopped working immediately - the display shows only a garbled set of half-characters.So much for that $18...

So, if you're looking for a novelty gift for someone turning 40 or 50, this is the thing to get.If you want a large, durable, easy-to-10-key desk calculator, then keep looking.

Review of Peanuts SNOOPY - Woodstock CALCULATOR

Average Reviews:

(More customer reviews)Paid alot for the item for it to be shipped in a plastic wrap with bubble wrap around it in the inside.The calculator looks like it's been sitting on store shelves for awhile because the the packaging was a bent up.But the calculator itself has a couple of marks.Will not ship back because that's more frustrating and I am bedridden.But will not buy from amazon again.I think I've learned a learn with this site one too many times.Thanks, but no thanks.

Review of Sharp EL-S50B Quiz Calculator 10-Digit with Punctuation/Math Drill Feature

Average Reviews:

(More customer reviews)My third grader does well with his times tables, but as any parent knows the goal is for times tables to be cemented in long term memeory.We have flash cards and even a rotating book, but he balked each time I brought them out.This calculator put the controls in his hands and he will voluntarly quiz himself each day.Fun and challenging and at his own pace, I am very happy with this product.

Review of BIG CALCULATOR

Average Reviews:

(More customer reviews)Product is generally what it's made out to be, with one notable exception.It is not a dual power item (just battery power), which was an important criteria for me (if you don't care about solar power, there are lots of other large calculators).Button layout is also different from the picture, but generally functional.

Overall the calculator works, but you have to be careful to press the large buttons right in the center, or your entry may not be registered.Not a big deal, but it means that you have to watch the screen carefully as you push buttons to make sure nothing is missed.

One other "nice to have" would have been comma displays in large numbers (e.g., 1,000,000 for one million, whereas the calculator displays 1000000).

Other than that it works like you would expect a calculator to; and the price is reasonable.

Review of Canon MP18D II Professional Desktop Two Colors Printing Calculator

Average Reviews:

(More customer reviews)I've had a habit in the past of working so intensely what I get going that I absentmindedly dump my calculator off on the floor. The last one took that kind of abuse a couple of times and then I had to replace it. I obviously wanted to replace it with the same kind and then hopefully not abuse it.

This one is serving my purposes well and I haven't dumped it on the floor yet. I have it fastened down with Velcro, so I won't do that again.

This machine is easy to operate and functions well. I recommend it.
