i've been to the testing center in College and the woman that talked with me wasn't too helpful on advice. Heres the thing i am looking for, i had to retake Basic Algebra because of reasons beyond my control. and i wonder if there is a calculator that can input the questions and give awnsers better. I have a Texas TI83 and i was considering to get the Texas Instruments TINspire CX Graphing Calculator or even the TI84 or 89 model i am looking for a calculator that can take 2 variables and solve both them, both Calculus and Graphing questions. so if it said Y=3x5 or 5=x2 or something even more complicated my calculator can support and handle them. i am confused and want to get past this class. as my major doesn't even go any further into math any and it is a requirement through the state only to go this high. Any help i greatly am thankful!

1) Having a calculator that can solve problems isn't of itself going to improve your mathematics. Any school/college worth its salt will have ways of ensuring that your grade relates to your level of understanding and not how good you are at finding a machine/system that will spit an answer back at you. 2) The internet is free and has all the tools you could possibly need. There are also plenty of offline apps. I think you should consider carefully what you are trying to achieve before you spend lots of money.

V8archie is correct. The best way to learn is to do it yourself. That said, there are tools that can help you check your answers, and to see if there is a solution in the first place. Some of them are completely free as well. Wolframalpha.com has already been mentioned. Even if you don't take the subscription and go free it can still help with quite a bit. There are computer algebra systems for the PC that are free. I typically use Maxima, and it comes with an extensive library of functions and graphing tools. It also comes with documentation. Sage is another option, and references Maxima for many things. Sage isn't quite as easy to use as Maxima, but has some advantages over it.

I'm taking up Computer Help desk support, as well as Systems and Programing. yes Programing does have instances where there is a required mathematics to give a solution, but i am not taking up computer programming as a main job career, its just part of the major i am taking up. I'll be working more with the Networking side, repairing and fixing computers, understanding Voltages and values. converting them and understanding the Fractions of the values as well. All of which i am comfortable doing and understand quite well. I'm just looking to get through one math class that has hurt me more because of the teachers end of things, when i needed help with my recent teacher he didn't offer any help, advice or examples. after this math class, the math learned from Graphing, Linear equations etc are not really useful after this class. that's why i'm not trying to look for the easy way out of things, but unless i get a good enough teacher or nice advice on the steps. I'm just wasting a good 400$ a semester on teachers i wished cared a little more then it being just a job

As a teacher, I can say that I care a lot more about students that put effort into understanding the subject than those who put in at least as much effort into avoiding the risk of learning something. If you already know everything that you will need to in your chosen career, I suggest you stop wasting your and your teacher's time and get the job that you claim you are ready for. My personal advice after 15 years as a student, 15 years in as a consultant in the telecommunications industry and 5 years as an educator is that learning how to study, understand and process problems in a logical manner is the most valuable thing you will ever learn, with the sole exception that however much you think you know it is nothing compared to that which you don't. The value in your college course is not in what you learn, most of which you can pick up on the job or by reading, but in learning how to think. You appear to want to cut that part of the course entirely. If you think a calculator is all you need to be the best you can be, you have a low opinion of yourself and are probably sell8ng yourself short. But it's your life. Live it your way. And if you already have all the answers, you don't need my advice.

After many hours of researching online from many sources to videos i assumed i was some what ok. when the exam 3 came i forgot my calculator and was in a spot where i was hoping i had remembered the calculator because i figured out how to solve for the X . even though i had to quit that exam early i told him i couldn't do it and what i had done. hes like no you are supposed to have found the solution for Y. i had emailed him prior to both exams as well as in person. Yes its true I'd rather skip this course, i had a course on learning how to program a Database, had programing in Visual Basic and many other courses and among those i couldn't remember certain things if you asked me. my school is rated 765 out of 821 schools in Ohio. my friend told me to switch schools because he learns so much from his school that hes actually learning things easier and better. If you aren't going to help i very much thank you for any of your guys help and support or guidance. i just wanted to know which calculator would be better usage to get past the mess i currently am in.
