Hey guys! Guess what, I had a bad cold last week, and have missed a few classes because of that. Now that our mid-semester are due next week I really need some help in topics like rules for adding, subtracting, multiplying, and dividing positive and negative integers and some other topics like adding matrices, long division and exponent rules. I was thinking on hiring some private tutor but then my limited budget meant that I couldn’t do so. I really need some urgent help in those topics, else I might perform really badly in my final exams. Can anyone make a suggestion ? I need some help, and I need it FAST!

I know how frustrating it can be if you are not getting anywhere with rules for adding, subtracting, multiplying, and dividing positive and negative integers. It’s a bit hard to help without more information of your situation . But if you can’t afford a tutor, then why not just use some program and how you go . There are an endless number of programs out there, but one you should get a hold of would be Algebrator. It is pretty helpful plus it is quite affordable .

I must agree that Algebrator is a cool thing and the best software of this kind you can get . I was thrilled when after weeks of anger I simply typed in hyperbolas and that was the end of my problems with math. It's also great that you can use the program for any level: I have been using it for several years now, I used it in Remedial Algebra and in Basic Math too ! Just try it and see it for yourself!

I remember having often faced difficulties with x-intercept, graphing parabolas and hypotenuse-leg similarity. A really great piece of algebra program is Algebrator software. By simply typing in a problem from workbook a step by step solution would appear by a click on Solve. I have used it through many math classes – Algebra 1, Algebra 2 and Algebra 1. I greatly recommend the program.
