Let Calculator Buy? Solucionario
All we got this question once, a few may not. But anyone who liked the numbers in school and planned to study any subject of science (engineering, pure sciences, economics, etc), or simply when I go to pref, or have the option, consider purchasing a calculator ... .. Here it comes
the dilemma,
calculator what "good" pa serve me throughout the race to buy? Even I ever ask this, but luckily at that time by pure luck I chose the best from that time ... Times change and tecnoligia increases and there is a lot more supply in our Bolivian market.
good to start choosing a calculator according to our requirements in science and technology.
Here is the list according to me are the best we have handy calculators to buy in our markets.
TI-Nspire and TI-Nspire Cas : According the best calculators I can find in our market also the hardest to locate.
1. Some of the unique features of TI-Nspire technology allows you to:

4. personal comments - calculator can include text or pdf documents word type or kind exel spreadsheets. So I used to have good form (as if Uzar Form no scammers) without having to edit equations.
- In the official forum page of titanium texas community you can find lots of dispobible software for all areas of engineering and pure sciences, including financial.
- speed calculator to what I saw is much faster than other scientific
- Its market size is what makes me choose this calculator to see a similar texas
voyage200 - as mode of use menus , is very intuitive, so it is easier to handle than a hp.
- Nspire The latest internet there is the touchpad, but still there to buy in our market and believe that it took about 4 years to have in our market.
Hp50g : An excellent calculator for all jobs in engineering and sciences. Many people already have the calculator is, yet many (90% of users) do not know how to use it well. A calculator that can safely compete with Texas, if you know you can manage to overcome many with rpn mode it has.
1. General Information ultimate graphing calculator for professionals and students in surveying, engineering, mathematics and science is even better. The new HP 50g graphing calculator features an SD card slot formatting functions, data entry RPN (Reverse Polish Notation), algebraic and textbook, the largest display of high contrast with more usable space than ever, RS232, USB and connectivity. It also features HP Solve, structured programming and Computer Algebra System (CAS). You also have the reassurance of award-winning HP support 24 hours a day.

- update the new screen, the new HP 50g display delivers 30% more usable space. Best
- connectivity RS232, USB driver updated and infrared ports.
3. personal comments - With the calculator you can share programs with people who already have this calculator or previous models with infrared connection. Since it is a highly commercialized calculator, there are many who will update the software on your calculator, so much material in our software.
- is physically much stronger this calculator with the 48GX, nomas bone is resistant to shocks in the header of plastic and cover (case) you have. also display has a protective mica (which does not have the titanium)
- now it is a cheap calculator (150dolares), tough, good-looking, and there is much material, however that is not the number one in this list, by simple fact that the mode of use is not intuitive at least have to read the user manual quickly, in order to handle regularly. a calculator is not going to be learning to operate by simple observation while passing the days of use. minimente because you have to resort to manual to know where to find what you need. For example if you want to make a linear regression in a titanium graphics you'll (by arrow keys and enter) and go there is the option. while you have a hp enter with shioft 8, define parameters or something I do not remember well.
- I have an old fashioned calculator hp as I said, but if I buy a hp50g tubiera cash, because its SD slot seems very interesting to keep formulas ...... jajajajaja.
TI-89 and HP49G +: Once again we have the titanium 89, texas instrument, costs about the same as a HP 50g, but if I say that compares with the HP I would say this on par with the 49g +. Several I will say that the 49g + and 50g are the SAME. yep I saw that they are the same characteristics (same chola with different skirt), but I see that the 50g has a better keyboard than the 49g + bone that is more robust. So compare the ti89 to the 49g +.

Although both calculators are manufactured in China, IT gives the appearance of being more robust, in addition to screws (not conventional) for repair. The HP has no screws, but equally they can disassemble and reassemble because the buffers that support can be cut and replaced with a screw.
IT has a rounded design and dark. The color of the label function is quite weakened which could hinder its reading.
2. Concluding Remarks (These comments are very interesting, extracted from external web na) user experience using the product educational "Texas Instruments is quite complete. The IT environment is enjoyable, intuitive and easy to use also the full range of applications including calculator will provide additional capabilities such as organizer, notepad, among others.
However, the IT base system does not reach the elegance with which HP does your calculator. Although HP is not even close to being a calculator intuitive and easy to use (even algebraic mode) all the elements interact as if it were a timepiece unlike IT, HP's operating system is a whole.
IT shows in every aspect that was clearly designed as a product for students.
whether to classify the HP, I personally put a product designed for engineering and not as suitable for first-year students.
If I ask my where I buy it .. it is very difficult to answer .... I'd buy hp that would be a challenge to learn it all and would serve me for my entire life, but learn it would take me some time and is the least bearing in early years of our career. then I bought a Titanium texas serves up to scam me on the Internet may also get a lot more material for this calculated that for a hp.pero ...... if it sucks or maybe I can do some things, as a serious hp as many have this calculator and I could explain, in addition there are courses for learning to program. but .... Could give many targets to choose from .. I would say choose either of these 2 as they both bring their advantages. But yeah, always take into account Buy a CalcU ONLY FOR ALL THE FENCE NOT CHANGING CAREER AS A TEACHER SAYS AS MUCH COVERED THE LITTLE TIGHTEN.
Texas Voyage 200 : I could not retire in this occasion without mentioning this calculator, which is better than the texas bag (according to an article I read), but also the most expensive at that price I could buy a laptop.
this calculator robust, with letters and numeric keypad and large screen is very nearly a small pc. has many benefits, programs, etc.
But the bad news ... is its size, is too big for my taste, and I think that if any time any teacher on a test that I see with the reviews and I calculated my books in pdf encuwentra within it. In college and saw people using this calculator and then saw them in exams and teachers do not bother, those .. but I also said that other teachers and would preclude the use of the calculator .. I think it depends on the teacher that ... bueo if quuieren learn more enter google.com
there is much information on the features of this calculator
Casio : calculator for excellence. There are many deals in our market. Also the price is affordable the most expensive I saw was one of 700Bs it was touch .... There are all kinds, and are very easy to handle, there are many engineers and science graduates to use a casio. So what matters most is what you know not so much the type of calculator. so for more advanced calculator you have that will not help you if you know nothing, and if you a good calculator is a plus one has to improve in the passing of your career.
All we got this question once, a few may not. But anyone who liked the numbers in school and planned to study any subject of science (engineering, pure sciences, economics, etc), or simply when I go to pref, or have the option, consider purchasing a calculator ... .. Here it comes 
3. Technical Specifications TI-Nspire: 
this day when I went to enroll, after having paid into a bank (which though it be in banks .. one looks the most empty) ... well ... career ......... schedules are already posted .. and surprise some already are beginning classes this week .. that shit .. do more things and thought these vagaciones .. that shit .... good for neither to do .. and note the matters cursare .. and then animated. each semester as I begin ... but in a bad mood because I did nothing in these vagaciones, and earn little money if you want .. poor so I will start this year ....
