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}] instead, or 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}] .
