Bought this for an 8th grader. My 49G was too complicated for her grade level.
1 July 2013
Summary: Have only tried out several of the built in functions but seems to be geared for learning as well as to be used as a tool. Bought because I like HP and did not want the RPN (which I prefer) for my daughter. Will be good even if she is ultimately required to buy the TI equivalent.
Summary: Everybody knows the Hp calculators are a high level instruments, and of course not to much people use it completely, so intend to discover all the functions its very hard, but in a simple way, the body is solid, the keys are good finish and easy read, the mode to typing is convectional to HP device, in conclusion really good deal,
Summary: I got this calculator at a GREAT price. I am used to using a TI, so I'm still not incredibly familiar with the HP, but it has done everything I needed it to do, and it's definitely worth the lower price.
Summary: To Whom it may concern: I have never owned an HP 40GS calculator. I have purchase a cover for an HP 48GX Graphing Calculator. I do own an HP 48GX Graphing Calculator. I used it when I was in school. I loved my HP and took great care of it. This calculator is one of the best for using any and all math functions, and also writing programs to use math. The part I like most is that I could write a short program in calculus using my HP and come up with an answer very quickly.
Summary: Both of my sons were required to have this calculator for their advanced math classes. My older son's stopped working properly at the end of the first school year. We took it back to the store and they were unable to fix it. We went on line to trouble shoot but nothing worked. We had to buy another one for final exams. The following year we purchased this required calculator for my younger son.
Summary: FINALLY - a graphing calculator for the 21st century, and the price is right! I never thought that word 'intuitive' could be applicable to an HP grapher but the 40GS is intuitive - user friendly. And unlike the TI's, it's not built like a kids' toy and the screen is clean and readable. Most HP graphers assume that you're an engineer and so you're smart enough to figure out how to use the calculator without any help.
