How can I get a profit function P(x,y) using a cost function C(x,y) and a revenue function R(x,y)

So I have 2 multivariable functions, one for cost and one for revenue, and I need to get a profit function. So how do I input a command that basically subtracts the cost function form the revenue function.
R(x,y) = 6xy + x^2
C(x,y) = 2xy+3x^2+y^4

Ran in:
x = 1; y = 1; % assume some input values
R = @(x,y) 6*x.*y + x.^2; % use funciton handle to define the equations
C = @(x,y) 2*x.*y+3*x.^2+y.^4;
P = R(x,y) - C(x,y) % apply the profit equation
P = 1
