does somebody know of a decent affordable calculator that can solve for "X" in an algebraic equation? Im not looking for capabilities to solve very complicated problems but just basic stuff.

READ THIS, no, really, listen to what I'm about to say...
Only use a calculator or computer to solve a problem when it's your LAST math class you'll ever take -or- you're required to use one by your teacher/professor for whatever reason.
I say this cuz you really need to know this stuff inside and out for each future class. If you have any lack of understanding, you will be miserable in your future math courses. Conversely, if you put forth a little effort today, you will make the future math classes easy!
Lastly, at some point in time, you will intuitively understand the problems you're doing and you'll know when you've made a mistake. I'm not proud of it, but I discovered this in my differential equations calculus class when I was working too much and didn't study much... I just knew when I was making a mistake on the exams and intuitively worked around my lack of knowledge for that particular material.
Don't use a calculator... you'll cripple yourself.
well its just for the simple algebra stuff when im doing a test and he throws it in and im crunched on time. The teacher suggested we get a calculator that can do simple algebra problems so yea thats why. I dont plan to rely on it, hell i cant ebcause i have to show how i got the answer

Pin it baby!
My calculator will....its a TI89 titanium. has a built in equation solver that will solve for any one variable, but it costs 180 bucks.
You can never be too Specialized

Ti89 is banned from the math dept.

that sucks....my teachers dont even have a clue how bad i can cheat on that thing, they are totaly oblivious to the fact that not only do i have the best calculator in the whole school, but i took a class at a comunity college that was focused on learning how to operate graphing calculators. I guess what they don't know cant hurt themOriginally Posted by phantomcow2

Skip math, go with a Behavior Science or Liberal Arts degree. . I'll never use algebra or calculus again!!!!
I am Signature-less
well the teachers here know about the TI89 very well, they walk around checking for any student using it. You can make it through calc without knowing hardly anything and still get an A with it

Almost all the Ti's can do that. I have a Ti89 and it can solve for multiple variables if you want. It's not banned in as many places as the 92, which has a keyboard.
Otherwise, just do the math yourself, it's the best thing you can do for yourself.
While we're all pretty proud of your calculator, and the subsequent posts bragging about its cost and abilities, for simply solving for a single variable, you can get any cheap Ti graphing calculator. As for the 89, you can snag one for about 80-90 bucks on ebay.Originally Posted by ChAnMaN
You had to take a course to show you how to use a graphing calculator? Your bragging rights are hereby revoked and nulled.Originally Posted by ChAnMaN
r u kidding me...do you know how many different fuctions those things are capable of....and its not just the graphing..you can download programs for every time of math problem under the sun.Originally Posted by operator

hmm, you cheat in math and your composition skills are lacking.Originally Posted by ChAnMaN
I SAID "NO KETCHUP" ON MY BURGER!
Yeah I know, have you programmed the calculator in assembly/basic? ....Originally Posted by ChAnMaN
Heh, I don't know how old you are but you're not helping your case when you sound like a 17 year old who just discovered how powerful a Ti calculator is. If you want real power, get a HP. Better yet, stay away from calculators all together. Calculators are good for easy stuff, that's about it. Believe me, you're not going to get any help writing a control system using a calculator even though technically it's all "math."Originally Posted by ChAnMaN
I give up. Sorry about the ketchup, i'll get right on that.

WOOHOO! High five! I use the skills I use in Spanish 10X more on a monthly basis than I use math. Honestly I am yet to use any of the skills from two years of Algebra, one year of Geometry/Trig, and one year of Precalculus outside of a classroom. The literary and philosophical reading I've done, in my opinion, is far more important than math.Originally Posted by HammerTheHill

I agree with this fully...I took Calculus I and am going to be taking Calculus II in the Fall semester at college...If you don't know how to do simple algebraic equations, then if you do go further into mathematics, it will become a lot harder without having learned those essential tips and rules. Some teachers/professors may require you to have a graphing calculuator later on in your mathematical studies, but if your in Algebra I, II, and Geometry a calculuator for doing algebraic equations isn't necessary...maybe a small one for arithmetic. It's really when you get into your trigonmetric functinons and higher order functions where a calculator becomes more necessary.Originally Posted by LordOpie
umm folks im not saying i want the calculator to do it all for me here. Its just when looking for an answer like the area of some shape on the cortesian plane it would be nice not to have to do the distance formula over and over. things like that

Download Maple, which is a math program, public domain. In fact there are bunch of them.
Then you won't have to get an 89 and an 86 and put the 89 in the 86 case to sneak it past teecher.
I had an HP49 emulator in my sony palm pilot, managed to convince a professor that it was a calculator.
