Texas Instruments TI 84 Plus Taschenrechner Silver Edition (in englischer Sprache)

i liked the cheap price compared to normal. No batteries were included, but after putting the batteries in it worked just fine. For my purposes, I did not care about appearances. I only desired a functioning calculator. The calculator had some minor scuffs and little bit of dirt but that can easily be cleaned with a alcohol wipe. All in all, it was a steal. I recommend anyone who wants a TI calculator to buy this instead of giving Texas Instruments more money.

Good for math student

Easy to use. Great price. Unknown if it had charging cables but we didn’t receive them. The batteries can be changed

Arrived on time, great packaging, totally as advertised

Item dont work

The calculator was needed for high school mathematics where it performs the needed function well and delivers what is expected.

Christopher Correa, ContributorSpotlight on social innovation, social entrepreneurship & social mediaLEADERSHIP | 7/18/2011 @ 5:23PM |2,614 viewsSocial Media Is Not Creating The Laziest GenerationSHARE:Today on CNN.com, comedian Dean Obeidallah wrote a fascinating piece with a premise that I'm still struggling with: Are social media creating the laziest generation?My gut reaction is to give an emphatic yes, followed by, "and get off my lawn you kids!" But I don't think Obeidallah is giving people enough credit:We are the reality-show generation. Instead of doing, we watch: We watch people sing, dance with B-level stars, fist pump, pawn stuff, pick a husband/wife, get extreme makeovers to their homes and faces, be `real' housewives, keep up, lose weight, go to rehab, get fired, survive.Reality programming is at a unique crossroads at this point, I think. Who is the "we" Obeidallah references, I wonder? Game shows and sports were being televised not long after Philo Farnsworth invented TV technology. But when I think of Reality Shows as they are recognized today, I look to MTV.Programming tracked Generation X as it evolved from disenfranchised youths resisting the cold, corporate setup (pop culture benchmarks include "damn the man" films like Reality Bites and Slacker) to eventually participating in it. One of the first reality shows that amplified the voice of this generation was MTV's The Real World, which did more than just peer into the day-to-day lives of a household of strategically cast teens and twentysomethings in the early 1990s. It broadcast a national sense of indifference, a demographic in pursuit of a holding pattern before succumbing to adulthood. By the end of the decade, though, that same group became less enamored of their televised avatars as peers; they got older, while the Real World casts stayed the same age. Traditional (read: old-school) game shows like Who Wants to be a Millionaire? and Survivor became the craze (there was even a short-lived revival of the 50s game show Twenty One, which was popular in Generation X's grandparents' day and hosted by their parents' entertainment icon Maury Povich). In spite of the fact that TV screens got thinner and more rectangular in shape, programming kind of got, well, more square.Sure, audiences watch people sing and dance--and on a more salacious level, exercise moral and sexual exploits purely for shock value--but what I come away with is the fact that, peeping tom programming aside, we're watching stuff that most of us can't do ourselves. I am among the vast majority of people who do not think they can dance. I also know my singing voice will never be idolized. I vicariously experience what I might only be exposed to on Broadway or at a concert. And--onslaught of product placements notwithstanding--I appreciate that side of the medium.Obeidallah veers into the virtual lifestyle next, calling the computer screen our entre into voyeurism. He makes a valid and important point, but there's more to social than he's giving credit.Sometimes, voyeurism can be less creepy, less sinister. Arianna Huffington said, "Self expression is the new entertainment." If anything, Facebook, Twitter, Google+ and YouTube have enabled us to be more interactive, and less passive.I like that social media can make journalists and pundits of us. I like that it can connect people and help save lives. Look at Hollaback, founded by Emily May, a network and blog that enables victims of sexual abuse to report incidents, share stories and support one another in real time. Or the Reinvent NYC.gov hackathon that encourages developers and designers to help transform New York City's web site and and empowers the city's denizens to define their home.Sure, social media can provide a platform for the profane and the puerile, but it also gives voice to those with something critical and useful to say. I'm glad that I found Obeidallah's article, which was sent to me via a Facebook message, and which I may not have happened upon without social media."Observing events and then commenting on them...has become our national religion," he writes. Sure, it is often abused like an opiate. But it also makes outliers--and sometimes, martyrs--out of people. The unfortunate events that befell Sean Hoare, the former News of the World reporter attest to that. I learned about his whistle-blowing, as well as his demise, via Twitter.Then Obeidallah lowers the boom:In the past, people would recount where they were when an historic event occurred such as the Kennedy assassination, the space shuttle exploding or the 9/11 attacks. In the future, we will instead recall what we tweeted, posted or read on social media platforms about such events.That's where I have to disagree. I don't think social media has made us lazier--not on the whole, anyway. It has perhaps made us less patient, but it's also made information more accessible and given us greater capacity to connect and change. When I was a kid, immediate gratification used to manifest itself as popping on a video game instead of going outside to play. But thanks to the Jane McGonigals of the world, gaming has gotten much more instructive, intuitive, informative. And activities like blogging--once considered a pioneering portal for citizen media, then maligned as an easily appropriated gossip tool--are still valuable platforms from which new ideas and opinions can thrive and encourage social change. They made this citizen journalism series on the evolution of the urban slum (written by the social entrepreneurs who are contributing to the urban slums' improvements first-hand) possible. They're responsible for this post, too.Obeidallah evokes Robert F. Kennedy's wisdom: "Few will have the greatness to bend history itself; but each of us can work to change a small portion of events, and in the total of all those acts will be written the history of this generation."Those acts, however random and small, can become targeted and mighty. Sometimes 140 characters can influence corporate social responsibility and even lead movements.It's a debate, I think, and one I hope will continue. Dean Obeidallah got me to thinking, and I really appreciate that. One thing's certain: I'll be following him via social media going forward for more insights--the question is, does that make me more or less lazy?SHARE:CommentsCalled-OutExpand All CommentsJ.

Ich finde das Produkt TI84 plus spitze, weil es die Realität abbildet.Wir sitzen vor Rechenmaschinen und müssen in Sekunden analysieren, ob die Maschine ein plausibles Ergebnis bringt.UND das ist das aber: Leider zeigt der Bildschirm nicht alle Einstellungen an und so irrt man zu Beginn durch den Taschenrechner, wenn man nicht auf die richtige Passage bzgl. Einstellung der Rechenfunktion kommt.Wir hatten ein zuvor benutztes (eingeschaltetes / ausprobiertes ??) Gerät und sind nicht darauf gekommen, dass eine Voreinstellung geändert sein könnte - selbst der Händler hat es als Reklamation anerkannt.D.h. Mathelehrer lasst nicht nur dicke Wälzer wälzen, sondern erklärt die Technik und setzt Euch mit dem Arbeitsmaterial auseinander. Z.B. warum sollte der CASIO CFX 9860 besser sein??Und nun kann ich mir zur Erst-Bewertung leider es nicht verkneifen.Der vor mir bewertende Rumäne hat offenbar nur gestaunt über die Möglichkeiten im Westen !!!1) Woher hatte er/sie das Geld für den GTR??Anm.: Das ist Scherz aus RV, Gruß an den Großen Kunsteis-Rumänen, der kein Geld für Bildung übrig hatte, warum auch.2) Es ist kein Scherz, dass nur ein Rumäne amerikanische Taschenrechner lobt ... warum?3) Wo sind die Putinschen Geheimwaffen ... oder lassen die Russen beim Ami denken?4) Warum wählen die Amis Romney?Keine Scherz-Antwort: Ey es muß doch einer auf das Niveau von Putin (runter!)

Sehr guter Taschenrechner auch für kompliziertere mathematische Aufgaben. Für Schüler in der Oberstufe sicher das richtige Gerät. Interessant ist vor allem die grafische Darstellung von Funktionen auf dem Display.
