Many thanks, Steve. I agree with that and got the same answer, but wasn't sure I was right. ALL the brackets confuse me.
So let us first work out (4) ^ 2
Thanks Steve. I meant.  4^2/3 . My answer for that would be16/3
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.
hi eunolwin
A number to the power of 2 means that you find the square of it. (eg. 5 ^ 2 = 25)
I'm struggling with 4 to the power of 2 divided by 3
