Could somebody tell me why the following code returns the following error?? 'Undefined function 'plus' for input arguments of type 'function_handle'.'

Error in @(h)Vbody+Vlungs+Vsuit

EDU>> rhow = 1025;
  g = 9.81;
  P0 = 101325;
  gamma = 1.4;
  m = 67;
  Vbody = 0.06;
  Vlungs0 = 0.004;
  tol = 0.01;
  %Anonymous Functions:
  P = @(h) P0 + rhow * g * h;
  Vlungs = @(h) ((P0)/(P))^(1/gamma) * Vlungs0;
  Vsuit = @(h) 0.005 * exp(-0.035*h);
  V = @(h) Vbody + Vlungs + Vsuit;
  EDU>> V(2)

I give all my constants numerical values and then define the anonymous functions Vlungs and Vsuit, both are functions of h. Finally, I attempt to define another anonymous function V, which is also a function of h, using Vbody (a constant) and the two previously defined functions of h Vlungs and Vsuit. Is this not allowed and if not, is there a way around this? Thanks.
