what is the command to find the rank of a polynomial?

actually i do not know the definition of rank of polynomial

i guess rank of x*y = 2 rank of x^3*z^2 = 5

i guess rank of  x*y+ x^3*z^2 is the maximum of above ranks, so it is 5

if i am wrong, please tell me, as i can not find in google, and there is no definition in my book
