HP 50g Graphing Calculator - Spanish

Spectacular and versatile calculator. Many useful programs available, but make sure you order a small SD card if you intend to use programs though, as it will not function with any SD card larger than 2 gb, and most available at stores exceed this now. Will take some practice getting used to as it has a less user friendly interface than comparable Casio or TI models, but it is much more powerful and versatile for much less.

There is no mention of "HP 50g+ Graphing Calculator" on HP's website. Maybe it doesn't exist? There are Amazon sources for "HP 50g Graphing Calculator" that are less expensive than this "+" product.

The Pros:* An impressive calculator, especially for its price.* The most functions I've seen (2,500 I think), with plenty of others synthesisable.* USB cable to connect to the computer.* Provides a Flash (non-volatile memory) storage area with about 677 Kb initially free.* Thankfully it has a SD card slot, if you can still find SDMC cards.* Awesome programming languages available, and even supports C programming if you use external tools.* Provides a filesystem with folders.* Uses 4 standard AAA and 1 Backup battery (CR2032).* A sturdy fabric case with a magnetic catch is provided.* Keyboard is clicky, not spongy.The Cons:* No colour display, but does provide 16 greyscale 131 pixels across, 80 pixels down.* Limited memory in comparison to later calculators (233 Kb), though better than most.* Only a QuickStart manual was provided. The other manuals are only available as downloads.* UserRPL and SysRPL have a very steep learning curve, though they are very powerful.* The serial connection over USB is flakey, and you can only copy individual files around.* Limited support for connections from Linux.* Battery lifetime isn't as long as other calculators, but still better than modern equivalents.* It's not a TI. It's better, but it doesn't have the support from the educational community that TI has.* SDHC cards are not supported, only SDMC. That means cards that are larger than 4Gb simply won't work in the calculator.I got lucky recently, and picked up this calculator for only $85. List price from HP is still $129, or thereabouts. Where I live, I would have been paying three times that amount. I'm pretty happy I finally have an HP calculator again. I once had a second-hand HP-34C, and have missed the unique clicky keys ever since. As many other people have already reported, this calculator keyboard has mostly fixed the issues that plagued the 49G. Keys make an obvious click feel, and don't double-click when you hit a single button.The case, while not hard, does look good. It won't break or develop weaknesses like the slide-on cases for other calculators will do, though it won't stop buttons from being accidentally pressed with books in a bag. This could be perhaps solved with a thin plastic shim inside the case, but you'd have to design that yourself.So far I'm finding that while I love the abilities of RPN, I'm still getting my head around the way UserRPL works. If you ever buy this instead of the Prime, get the manuals, and the Advanced User's Reference, as those will help you make the most of this calculator. There are plenty of older HP48 programs that will work, though not everything will, especially programs making use of SysRPL functions that may have changed between the 48S/SX/G/GX and the 50G.There are some known issues with the software that connects the calculator to the computer. In some cases, it doesn't really work well, and in others, it performs well enough, if you know what settings to use. It would pay to do a little reading, or simply use the SD card with a card reader if your computer has one installed.I'm happy.

The HP50g is an outstanding calculator; I have used it for a few years. I like RPN mode;How it works with and converts units .The Equation writer is outstanding.The matrix writer is also. The catalog of equations and constants is very useful.I highly recommend the tutorials by Mr. Gibson at Mathtutordvd.com:: They are outstanding and the best way toget the most out of your calculator.

This is a great calculator, but it is not easy to use. I preferred my HP-42 but it has been discontinued. I just didn't have the time to spend on learning how to use it. It just sits on the desk as a paper weight. Now that I have an iPhone I just use the hp-42 clone (free42). HP should really supply a decent user manual, downloads are great but I would rather have a decent manual just like my old 42 came with.

Good product and it arrived at the estimated time

Too complicated for my daughter.

No problem with the calculator, but it was packaged as a Spanish version. The hard copy instruction manual was worthless since it was not in English. Not a huge issue, but should have been specified prior to order placement.

Esta calculadora te va a fascinar en cuánto aprendas a utilizarla. Vas a alucinar con las funciones que tiene y la cantidad de problemas matematicos complejos que resuelve. Impresionante.

今まで使っていたCASIOの(通常の)関数電卓を水没させてしまい、代替機として導入しました。RPN入力方式が便利そうと思ったので、自ずとHPを探すことになりましたが、最新型のレビューの評価が散々だったので、敢えて旧モデルを購入。良かった点、不満だった点　それぞれあるので箇条書きで紹介します。良かった点・RPNの使い勝手は期待通り。多少の慣れは必要ですが、その後は複雑な算数もストレスなくこなせます。　ただ、(これは不満の側になっちゃいますが)数値入力の履歴が残ってくれると、もっと便利だと思います。　現状仕様では、計算が複雑になった場合、どこまで計算したのかわからなくなってしまうことがあり、　また、同様の計算を複数回繰り返すとき、毎度同じ操作を繰り返す必要があり、少々面倒です。　(今では通常の関数電卓でも、ちょっとグレードの高いものなら数式通り入力と、その履歴まで残せるので　このままでは従来型の使い勝手に負けてしまいます)・キーのタッチは評判通り秀逸です。クリック感が気持ちよく、使用にストレスありません。　キー角度も操作しやすく、長い経験で設定された最適値なのだと思います。不満だった点・筐体サイズが巨大。その昔のポケコン並みです。国内メーカーの同等機能の製品に比べて　面積で3割増し　はともかく、厚み3倍！です。・電源も乾電池なのはまぁいいとして、単4 x4本！です。　しかも相当の大食いで、1～2ヵ月使用で電池切れになってしまいます。(PanasonicのEVOLTA使用にもかかわらず、です)　他モデルはソーラーで賄っており、電池の心配無用なだけに、これは大きなハンデです。・高機能なのである程度仕方がないのですが、メニューの選択が複雑でわかりにくいです。　RPN方式が選択式(通常の数式通り入力との選択になります)なのはいいのですが、　その選択メニューの階層が深く、しかもわかりにくいです。サイズや電源については、アメリカのメーカーの特徴というか悪い面が出ちゃってるように思います。・この手の電卓には、RPN方式のみを求めて購入する人も多いと思うので、　もう少し下位モデル(グラフ機能は不要。今ならExcelでいくらでも作成できます)で、　関数機能とメモリ機能のみ充実させ、より小型のソーラー式　といったモデルがあるといいのですが、　何しろ世界でRPN方式自体がほぼ絶滅状態なので無いものねだりなのかもしれません。それでもRPN方式自体は非常に使いやすく快適な入力方式なので、どこかのメーカーで復活してくれないかと思っています。複雑なアルゴリズムでもなく、ただのソフトの違いですので、RPN方式の電卓を作ること自体は、どこのメーカーでもそれほど難しくはない(コストもほとんどかからない)ハズなのですが…

Me vino abierto, y faltaba una pieza

Very disappointed with the high price paid especially since it was not in it's original packaging. The box was also damaged. Not sure if this is a used product that was returned.Very displeased for the price.

Fast shipment. Everything alright.
