Check your syntax.  :)   "2" is not a function, yet the way the function is
typed---with the square brackets to imply multiplication---makes Mathematica
think that "2" should take the argument of Sin[x+Sin[y]]. Try

Plot3D[2*Sin[x + Sin[y]], {x, -10, 10}, {y, -10, 10}]

Plot3D[2(Sin[x + Sin[y]]), {x, -10, 10}, {y, -10, 10}]

or

Plot3D[2 Sin[x + Sin[y]], {x, -10, 10}, {y, -10, 10}] .

Hope that helps!
