SOLUTION: I have a question for example
1/2xy^2 when x is 4 and y is -2 do you have to put the expression like
1/2*4*-2^2
Or
1/2*4*(-2)^2 with the parentheses? I always gets confuse

You can put this solution on YOUR website! Yes!
your second assumption is the correct one:
Always seperate the signs with parenthasis so as to atract a better mark.

is correct since you have to SQUARE the value of y, which is - 2.
First expression: ------> ------> .
Second expression: -------> --------> .
Do you see the difference?
