Depends on what substitues those letters. It can be an infinatly amount of numbers that can be put into the place of those letters.
d + f.
d+6 or 6+d
a d = fDivide each side of the equation by 'd' :a = f/d

The sum is the answer when you have added. ex. 2+3, the sum is 5.
#include#includeint a,f,n,sum=0; printf("Enter any number"); scanf("%d",&n); f=1; for(a=1;a<=n;a ); { f=f*a; } for(f=1;f<=n;f ); { sum=sum f; } printf("sumation of factorial numbers :",sum); getch(); }
d is part of algebra because it is a letter. Any letter in algebra is known as a variable. D is different from d in algebra. They are different.
the answer to the addition problem
Sum is the answer. Just like in regular math.
You don't really give enough information to answer your question fully. In maths, a "product" is what you get when you multiply things together. So A x B is the product of A and B. A sum is adding them together. So in general, a "sum of products" means you have multiplied together several groups of numbers, and added up the results, such as: A x B + C x D + E x F. What that means to you then depends a great deal on what A, B and so on are!! In particular, two important "sum of products" formulas are in expanding a polynomial in algebra, and in simplifying truth tables in boolean algebra (for designing logic circuits).
