If you're looking for help on specific problems or trying to understand something singular about accounting, like "what does P = C (1 + r/n)^(nt) mean", then please put up the specific question so we can help you here.
In order to help you the best we'll need to know some of this information:
a specific question such as an example problem
a specific topic like "simple interest" or "intercepting parabolas"
an idea about what your teacher has tried before
how your teacher words the specific jargon for the subject
What specifically is confusing about the subject
How you've attempted to learn the subject, which hasn't worked
No one can learn an entire subject an a night, and no one can teach you an entire subject in a night, so we need some details about what you're having trouble on. If you're trying to cram for an exam and you're not aware of what will be on it, then I'd suggest asking your teacher for a study guide, or go over your homework and notes from the year.
There are also some wonderful sites out there which can help you with this sort of thing such as searching youtube on specifics like "Word Problems" and finding something like "Beginning Algebra & Word Problem Steps".
A lot of people have trouble with math and science so there are resources out there to help, you just have to take a bit of time to search it out. Once you do find that thing which clicks, be sure to remember where it was so you can go back for future help too.
But I suppose that's aside the point. The statement still stands. If you're looking for help to study for a test, you're going to have to give us some more specifics about what your teacher is looking for.
