Hello friends, I lost my math textbook yesterday. It’s out of stock and so I can’t find it in any of the stores near my place. I have an option of hiring a private instructor but then I live in a very far off place so any tutor would charge a very high hourly rate to come over. Now the problem is that I have my exam next week and I am not able to study since I misplaced my textbook. I couldn’t read the chapters on add and subtracting percentages and add and subtracting percentages. A few more topics such as hypotenuse-leg similarity, exponent rules, linear equations and evaluating formulas are still confusing me. I need some help guys!

Kids can’t seem to think of anything beyond extra classes . Why don’t you try something yourself? There are many resources for add and subtracting percentages which are much better than tutoring. Try Algebrator, and you will never need a tuition .

When I was in college, I faced similar problems with trigonometry, graphing circles and complex fractions. But this superb Algebrator helped me through all my Remedial Algebra, Intermediate algebra, and College Algebra. I only typed in a problem , and step by step solution to my algebra homework would appear on the screen by clicking on Solve. I highly recommend the Algebrator.

A truly piece of math software is Algebrator. Even I faced similar problems while solving hyperbolas, multiplying fractions and midpoint of a line. Just by typing in the problem from homework and clicking on Solve – and step by step solution to my algebra homework would be ready. I have used it through several algebra classes - Remedial Algebra, Remedial Algebra and Basic Math. I highly recommend the program.

Hello again. Thanks a lot for the useful advice. I usually never trust math software ; however, this piece of program seems worth trying. Can I get a link to it?
