Many thanks, Steve. I agree with that and got the same answer, but wasn't sure I was right. ALL the brackets confuse me.

Thanks Steve. I meant. - 4^2/3 . My answer for that would be-16/3
Whereas (-4)^2/(-4)^3 is -1/4?

My problem is the brackets. The calculations are fine, but it seems sometimes the brackets affect whether the answer is + or -. I know that 2 negatives multiplied become positive, but it seems that certain brackets change this.

I'm struggling with   -4 to the power of 2 divided by 3
  (-4) to the power of 2 divided by (-4) to the power of 3
  -(-3) to the power of 3 divided by -(-4) to the power of 3
(-2) to the power of 0 divided by -4 to the power of 0 and others of the same ilk.

Is there a section I can study on your site?
Can you give me the gist of how to do these, please?
Many thanks:
