work done is scalar quantity?

When we multiply two numbers, all we get is another number. But vector quantities can be multiplied in two different ways, scalar and vectorally. So we just combine force and displacement, the two vectors into a scalar product and name the resultant number as another quantity work. Also trying to assign work, which is just amount of energy spent, a direction is meaningless.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
