what basic math sttuf i should learn before i start an accounting course?

Accounting requires very little actual math. All you need to know is how to use a calculator, the rest is basic arithmetic. Finance has more maths than accounting.

I do not know why people think accounting is hard maths, it is just basic additions and subtractions. Nothing past year 10 math in accounting. Not even calculus.

The hardest math you would come across in accounting would be like :

Solve 3x+2 =4

If you can solve that then you can do maths in accounting.

Your first class in accounting will be an introduction to bookkeeping, which uses very little math. Bookkeeping is knowing what categories to record money in. Income versus expenses. Credits versus debits. It's all detail, very few calculations. And you have to pay a great deal of attention to that detail. It's easy to get mixed up. The only math you need is high school math.

I've never taken a finance course, but I think it requires using logarithms and exponentials and such. All on the calculator. There is also probably some algebra involved. You should ask your course advisor what the math requirements are as the college has its own rules. If you have not taken any math classes for a long time, you will need a refresher course. You could audit an algebra class for that (no tests, but you still have to pay for it, that's the price).

the short answer is addition and subtraction. These are the two most important. Remember in accounting that all ledgers and sheets MUST balance out. Therefore whatever you add to 1 account needs to be subtracted from another.

Not a lot I don't think. Try to get your percentage increases and decreases sorted. Ratios and basic statistics ie interpreting graphs. I have very little accounting experience but I can't imagine it would be much more than that.
