@Kitonum okai what if i make it a little more advanced and add an ekstra variable i  have these knovn values for the variables, gamma__w, z, and h 

gamma__w:=10

z__0:=2         z__1:=1              z__2:=0

z__3:=-1        z__4:=-4            z__5:=-7

h__0:=2        h__1:=1             h__2:=0

h__3:=0        h__4:=0             h__5:=0

and i want maple to calculate them using the equation "gamma__w * (h-z)"

how would i do that ? 

@Kitonum i was thinking more the other way around, so i already have the different values[x_0,x_1,x_2] but i want it to give me the answers they produce by substituting the variables for x ?
