What is the rest of the problem?

This is pretty basic algebra and if you are in an electrical certification program or any other program for that mater you may want to consider taking some math courses before you try to continue.  I'm not saying that you can't nuc your way through it, but it will be allot easier on you if you take a step back and strengthen your math skills before tackling an electrician course.

I'm putting my college education to use: by answering algebraic questions on answers.yahoo.com

u can even use calculus to find this out

Pay attention in Math class and the Professor will teach you how to solve it.

http://purplemath.com/modules/index.htm\n\nis an awesome resource for all kinds of algebra topics, even ones you may have forgotten and need to brush up on.\n\nTake a look at that one.\nUMRmathmajor

Basic math/algebra. You are taking two known numbers and finding the unknown number. \nE=P/I  solve for I    Think like simple Algebra I is X. So you want to work the problem and get a final answer x=?  or   I=?\nHope this helps.

Yes, many people do know how to solve that problem.  They learned it the same you should: read your book, go to class, talk to TAs, and do your own homework.

Division and multiplication. Just like I learned in Grade 3.

My favorite site for explaining Algebra (including intermediate and advanced algebra) is http://www.purplemath.com/modules/index.htm but it doesn't have worksheets available.  \n\nFor practice questions, look under CyberExams at http://www.sosmath.com/ \n\nYou may also check with a math teacher at school or at a local university.  Often, they will have texts that are no longer used that will have sample problems for you.  They may also have additional materials that came with the texts that they do not use in class.  I have also found some college textbooks at thrift stores near campus, especially when they change to a new version or author.

http://www.math.com/ or http://www.gomath.com/algebra.html are good places to start.

How many students failed the course?  If it is only a few and most students passed, it may not be the teacher's fault.  Algebra can be tough, and not all of us are able to do it easily.  \n\nThroughout your schooling you will probably have to cope with a number of teachers who teach in a style that doesn't work well for you, so you need to let them know your problems and work out a plan to do something about them.  Sometimes teachers can be very helpful if you can explain why you don't understand something, or what it is you don't understand.  \n\nIn the end, we are all responsible for our own learning, so check out the summer schools in your area or get a tutor.  Possibly ask for help from another student in your class who did well - that student may have some insight into the teacher's teaching style.  Lots of students need some extra time to master algebra, and while it can be very frustrating, it is often because of a combination of factors, including a tough curriculum, large classes, etc., not just the fault of the teacher.\n\nGood luck with it.

algebra is a broad topic. try to go back to ur notes and look for the formulas that your teacher has given to you. better to stick on what is in your notes and textbooks. try this also, ask someome who has taken this subject before...his information might help you...good luck.

That is a long problem to work out for only two points--it is simple algebra though.

I think it is not but it is used in Intermediate Algebra.
