Texas Instruments TI-83 Plus Graphing Calculator

Childrens Toy Shop > Office Products > Calculators

2004
This calculator is very well put together and very sturdy. The design is also easy to use and the buttons easy to press. The calculator performs all of it's functions correctly with only a couple of hookups that are usually a result of complicated mathematics. Overall this calculator lives up to the reason that schools and others alike put their trust in this machinery.

Texas Instruments TI-89 Titanium Graphing Calculator

This is absolutely essential for anyone taking a Calculus class. This is especially true for later on, such as in the later half of Calc 2 and all of Calc 3. After learning how to manually evaluate integrals and differentiate, as you move on to higher level concepts the 89 titanium can be used to do these manual tasks for you, allowing you to focus on the new material and allow you to practice more without wasting time on repetitive evaluations. I love this thing, and would not take Calc and Physics without it.

Texas Instruments BA II Plus Professional Financial Calculator

Childrens Toy Shop > Office Products > Calculators
from: Texas Instruments

2004
I have two previous BA calculators from TI and this one is impressive in appearance and touch. Regrettably, the first function I tried failed.
The calc. has a default date value of 12-31-1990 although you can enter your own dates for number-of-days computations. The problem is that the calculator accepts the year value as two digits as in 08 and not 2008. The consequence is that I can't calculate the number of days prior to 2000 (00). How about long term bonds? The user guide and calculator delivers ERROR 6 when I attempt a four digit year. Perhaps someone knows a work around but the manual and calculator are no help discovering it. Why doesn't TI allow date inputs like Hewlett Packard: 01.011950?

This product contains good manual itself, so you don't need to buy another book to learn how to use it. I didn't realize this so I bought a "useless" manual.

HP 50g Graphing Calculator (F2229AA#ABA)

Childrens Toy Shop > Office Products > Calculators
from: Hewlett Packard

July 15, 2006
This is a great calculator, I've had it for about a month now.
It does have a bit of a learning curve.
I had to spend about 2 hours reading the online guide in order to learn how to use the different graphs, as well as how to work with the new menus, use RPN, and other things like solving simultaneous equations.

One thing I really like is that this calculator (unlike the TI 89) has a equation writer. If you have a large and complex equation you are able to input it in without using alot of parentheses, (()(())). You can also edit the equations inside of the equation writer. With this you have alot less mistakes and if you do make a mistake it's usually obvious that the equation doesn't look just like it should.

I got exactly what i wanted and it took only a couple of days to get here. The calculator worked as if it was new. I bought a used calculator and it wasn't defective. It didn't have any major scratches and it worked fine. No complains here.

light, sturdy, ease to use, big keys. Its Casio!
Just one thing: there is a new function (key) that I can't figure out for what is it worth, even if i've read the small manual trhee times.

HP 35s Scientific Calculator

Childrens Toy Shop > Office Products > Calculators
from: Hewlett Packard

2004
My personal opinion is the 42s was the pinnacle of pocket sized excellence. The larger models afterwards are too big physically to be handy. I use: 42s, 35s, 48sx, 33s, Ti-89 (in order of preference). Primary use is electronic design, base conversions, using many self-coded macros/functions/programs in the calculator.

The 35s offers a "HP 42s Lite" in a way. In all, I miss the label/menu interface used on the 42s. I'll buy another 35s just in case, though, since HP seems to be drifting away from making Good Calculators, and compromising to the the "= user". The 35s is the first sign I've seen in 10 years that HP realizes the market for a True Programmable RPN Calc.

Things to note about the 35s, vis a vis 42s and other ... Read More:

HP 10bII Financial Calculator

2004
i have read a lot amazon ratings before making the purchase.
i bought this product three months ago and it is still working fine.
i think it'll working this way for i do not know how long.

the size, the weight and the feeling when u touch the calculator is good.
there is enough screen to read with no problem plenty of numbers.
the design is simple and gives enough bells for the eyes to like what they see.
the keys are also well made so there is "i did not push this number without paying attention."
the price is around $30 and if you are a student you'll probably like that.
we are talking about a quality product here.

conclusion: buy the hp 10bII if you need a financial calculator.

HP 12c Financial Calculator (12C#ABA)

I bought my HP-12C way back in december 1987, and except for replacing the batteries, it just keeps crunching out the numbers. I've had many, many calculators since late 70's and the HP-12C has been my favorite and I consider it to be the best calculator that will ever be engineered. Just my opinon..........
