I don't have a single homework question but a general one that will help me out tonight. I am taking calculus one college level and we are reviewing logarithms and I am really having trouble. I just don't understand how we are supposed to know where to add and cancel them.

It seems that at certain points in the math you just add a logarithm for it to cancel something out in a later time in the problem. This is really confusing me.

What are some good tactics to approach the problems when dealing with this type of math?

Thanks
