%Solution to P6
disp ('P-6');
res=0;
A=magic(4);
for row=1:4
for col=1:4
if A(mod(A,4)==0)==0
res=mat;
end
end
end
disp(res);
This is my code.

Hey Noah this should be the code. Just incase you didnt get it yet.
disp('P-6');
res=0;
a=0;
for row=1:4
for col=1:4
if mat==mat
a=magic(4);
a(mod(a,4)==0)=0;
end
end
end
disp(a);
