How can I add the elements ascending in this code

Mf=6.480554950317725e+03;
y=0.005338551179592;
D0=Mf*y;  % Product of 1st stage
D(1)=D0;
M=Mf;
for  c=2:15 % Product profile 
    D(c)=y*M*(1-y)^(c-1);
end 

____

By the previous code the product of D will be a matrix of size 1*15 (1x15 double)

Now I want to apply the following equation, which is based on a cumulative summation of the values of D :

B1=Mf-D1

B2=Mf-(D1+D2)

B3=Mf-(D1+D2+D3)

B4=MF-(.....)

Up to B15

B = Mf-cumsum(D);
