I just discovered that I am already late in dealing with some issues with simplifying exponents division. I had kept it waiting hoping that I will come upon high quality learning material or someone who can lend a hand with side-side-side similarity, long division and 3x3 system of equations. May be, I did not search hard enough. But now I am running late . It is simply not easy to get a good tutor to quickly teach me. It is beyond what I can manage to pay for . And I need to find a immediate way out. Can anyone who has had similar problems advice me as to what I can do? It will be a great help.
