Sure.  The derivative of x^3 is 3x^2.  That should get you started.

Yes you can. Its not scientific and it is really ugly, but it gets the job done.\n\nTo find it, just go to add content and type in the search box "calculator". You should be able to find it.

that is a really simple question, so if you have a calculator you should be able to get it, otherwise, it is your homework and I refuse to give you an answer to your homework. I would actually HELP you to get the answer if you asked for HELP doing it.\n\n-EA

I think a calculator would be great for this one! It sounds perfect for a math wiz to try...Good luck! MayMay

well if they cannot do simple math on a calculator the teacher can see that there is a REAL problem with the student.\n\ni remember doing a little calculator session back in primary school. it was basically to learn how to use a calculator which is a skill you need to a degree but it only went for a week or so and then we went back to mental calculations and used calculators occasionally to double check our answers.\n\nDoing math on a calculator all the time achieves nothing.

Depends on what calculator you use...some are +/- and some are just -. So it depends...Sometimes you have to push 2nd function to get it.

Here's a hint.  Google has a calculator.  And a search feature.\n\nDid you even read your questions?  The last one isn't something we could do for you.  If you're going to try to get people to do your homework, at least be subtle about it.

maybe you could try practising. For maths, the phrase practice makes perfect is very true. hmm...short cuts in multiplication and division...maybe you could try learning the abaccus (a mathematical instrument used by the chinese => functions like a calculator, but manually powered, no batteries)...I only know how to add and subtract using it...

There are several simple rules for re-arranging and solving equations.  It would be in your best interest to try and learn them, they aren't very hard.
