The resulting number is their "sum".
The two numbers that are being added are each called addends, and the result is called a sum.
Sum
The product of two numbers is the proceeding result when two numbers are added together.
Yes.
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.
The result is called the quotient.
The result of two numbers being divided together is called the quotient.
The result is called the sum of the two numbers. The operation of addition is commutative. This means that the addition of two numbers will give the same sum regardless of the order in which the numbers are added.
If there is an even number of data points in a set, there will two numbers which "share" the position of being the median; in this case the numbers are added together and the result divided by 2, to give the median for that set.
The addends
If you are asking what the result is called, there are two terms for it: difference, and remainder.
