    not quite right either - an absolute value is the distance away from 0. so if an ENTIRE problem is in \[\left| these \right|\],then it doesnt matter if it is negative or positive. it will be positive ALWAYS if the ENTIRE problem is in the symbol do u understand do far?

    ok. so solve for inside the symbols. in this case the ENTIRE problem r in the symbols, so u can ignore the - and positive signs i put emphasis on "entire" bc if the ENTIRE problem is not in the symbols, the rules r different
