Hello math wiz. I am facing some difficulty. I simply don’t know what to do. You know, I am having difficulties with my math and need urgent help with when solving a rational equation, why it is ok to remove the denominator by multiplying both sides by the lcd. Anyone you know who can save me with adding fractions, decimals and sum of cubes? I tried hard to get a tutor, but failed. They are hard to find and also quite expensive. It’s also difficult to find someone fast enough and I have this test coming up. Any advice on what I should do? I would very much appreciate a fast reply.

Due to health reasons you may have missed a few classes at school, but what if I can you can simulate your classroom, in your house? In fact, right on the computer that you are working on? Each one of us has missed some lectures at some point or the other during our life, but thanks to Algebra Buster I’ve never been left behind. Just like a teacher would explain in the class, Algebra Buster solves our queries and gives us a detailed description of how it was answered. I used it basically to get some help on when solving a rational equation, why it is ok to remove the denominator by multiplying both sides by the lcd and percentages. But it works well for just about everything you can think of.

multiplying matrices, simplifying fractions and conversion of units were a nightmare for me until I found Algebra Buster, which is really the best algebra program that I have come across. I have used it frequently through many algebra classes – Remedial Algebra, Remedial Algebra and College Algebra. Just typing in the algebra problem and clicking on Solve, Algebra Buster generates step-by-step solution to the problem, and my algebra homework would be ready. I truly recommend the program.

Don’t worry pal. As what I said, it displays the solution for the problem so you won’t really have to copy the answer only but it makes you understand how did the software came up with the answer.
