Hi everybody, I'm new to this forum!

I'm having hard times trying to live with my disapoint because its marketing material says that it gives you the result step by step, i could not find anything like this on the manual and reading other peoples post asking for it, (buffer), anybody told that it is not possible. (shame on you Casio!)

Anyway, in that post somebody said it would be possible with eActivity, my ClassPad gave me about 5 manuals but in english or spanish (the two languages i know) it seem to be chinese for me so any of you could help me with an example of how to build an eActivity to solve for example this cuadratical function step by step to the final graph?

y=f(x)=(3x-2)^2-(2x-3)(2x+3)-9

I think with an example of how to do this i could create the other i need

Is it true that i can create an eActivity to solve things step by step and then use it changing values to solve algebra?

Thanks a lot (if not possible, by now my classpad is less than useless for me )

Hello

..its marketing material says that it gives you the result step by step

Can you please post the address? Personally I havent found a site stating such feature.

my ClassPad gave me about 5 manuals but in english or spanish (the two languages i know) it seem to be chinese for me ..

I am pretty sure you are able to carefully read your manuals. Additionally, CASIO manuals are among the most understandable and easy to read ones. Compare with those of HP, for example.

by now my classpad is less than useless for me ..

After reading manuals with enough time and asking people you will surelly change your mind. If not, thats not a calculator for you.

well, "gives you the result step by step" is refering to the history updating the classpad does (and does very well). as for an e-activity I believe that they mean you can use an e-activity to demonstrate how a equation can be solved... i dont think it will actually solve it for you (but im not sure).

Here is one address that states this. I've seen others as well.
This site-

well, "gives you the result step by step" is refering to the history updating the classpad does (and does very well).

I don't think that is what the marketing material implies. If you enter the whole formula, the history only gives you a result. It in no way even hints at the process it used to arrive at that answer. This is one of my problems with algebraic calculators in general, but most do not claim this ability.

"By using the highly functional CAS (Computer Algebra System) in calculations, it not only provides the numerical value of the calculation result but it displays the complete process of the formula as a result. Thus it enhances deeper understanding of mathematics."

I am pretty sure you are able to carefully read your manuals. Additionally, CASIO manuals are among the most understandable and easy to read ones. Compare with those of HP, for example.

Yes, this is absolutely right, i'm also sure if i read the manuals more deeply i'll understand the caculator better, but what it lacks (the manuals) are application examples, anyway this is for newbies not only in classpads but also in algebra like me, however, i found that even when what the maketing claims is absolutely false, i still think eActivities could be of any help when i finally get a decent level of understanding on how to create one.

Thanks!!!!

"...but it displays the complete process of the formula as a result..."

Yes, I think this is a confusing statement on the CP300 web page!. I would change it for something like
"...but it displays symbolic solutions too..." .

I hope CASIO is working on the step-by-step feature, as well as on other features shown in this forum.

Ok, despite this fake announcement, definitelly if you see the pictures, it refers to the eActivities, i'm trying to get a better understanding of eActivities because it may be a usefull tool if there's a way (and i think there is) to make it interactive enough to create guided interactive excersices on the operations needed.

I've made my first eActivitiy, of course, a basic one, but i'll try again to find out where this fancy calc really stands! i'm starting to like it.

By the way, it would be the very first calcutator as i know that makes the entire proccess to a given calculation,if you guys at Casio append this functionality on the next month's OS upgrade for the ClassPad 300 !!!! (this emoticon its really funny! jejejeje)
