excuse me, but if tow numbers are enclosed in parentheses, next to each other does this mean to multiply them, it looks like this (-1)(-2) or what does it mean, also, could some explain to me what it means when there's an equation enclosed by brackets, kinda looks like this {3t+-(2)} so does the one in parentheses goes first or what?

yeah you need to multiply them.. and what help do you need with the second one? the one in parentheses goes first but i can see only "2" in parentheses. in this case you can simply take it out removing the parentheses..
