Force is a vector
Displacement is a vector.
Work done = scalar product =  force . displacement
W = Force * Displacement * cos Ф  ,  where Ф is the angle between force and displacement.
Scalar product is also :  Wx =  Force in x direction * displacement in x direction
                               Wy = force in y direction * displacement in y direction
   W = Wx + Wy

vector torque = R X F = cross product of displacement (distance) R of vector F force from origin.
       Torque =  R F sin Ф  where Ф is angle between R and F. (from R to F)
   Vector product is a vector which has direction =  perpendicular to R as well as to F.  This is given by thumb rule or curled fingers rule.  Toque is perpendicular to plane containing both R & F.

Let i j k be unit vectors along x, y , z axes. 
F = Fx i  + Fy  j
S = x i + y j
W = dot product =  F . S =  Fx * x  +  Fy *  y
vector product is =  F X S =  Fx * y  k  -  Fy * x  k
i . i = 1    i.j =0  i.k = 0      j.j = 1
i X i  =0    j  X j = 0
