The sum of two numbers is an equation. Depends on the two numbers being added what the answer will be.
If one of the two numbers is 2, the sum of two prime numbers may sometimes be a prime number. Examples of this are 2 + 11 = 13, 2 + 521 = 523, 2 + 281 = 283. There are an infinite number of similar examples where the sum of 2 plus a prime is another prime. However if neither number is 2, then the sum of two prime numbers is always an even number greater than 2 and therefore composite.

The sum of two numbers is a whole number if both of the numbers are whole numbers, or if the sum of two fractions can be simplified to a whole number.

Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------
The sum of two numbers is an equation. Depends on the two numbers being added what the answer will be.
The sum of two numbers is the result given when the two numbers are added together. For example, the sum of 2 and 3 is 5.
If one of the two numbers is 2, the sum of two prime numbers may sometimes be a prime number. Examples of this are 2 + 11 = 13, 2 + 521 = 523, 2 + 281 = 283. There are an infinite number of similar examples where the sum of 2 plus a prime is another prime. However if neither number is 2, then the sum of two prime numbers is always an even number greater than 2 and therefore composite.
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26

The sum of the numbers given is 31. 1 + 2 + 4 + 8 + ... + 2n = 2n+1 - 1
int i, sum = 0; for (i=0; i<20; i+=2) sum+=i;
