In an addition sum, if the missing number is the first number, for example, x + 5 = 10, then to find x, perform the sum 10 - 5, producing the solution x = 5. In a subtraction sum, if the missing number is the second number, for example, 7 - y = 4, then to find y, perform the sum 7 - 4 = 3, production the solution y = 3.
The sum.
The numbers that we add together are called "addends." When we perform the operation of addition, the result is known as the "sum." Each addend contributes to the total sum, which represents the combined value of all the addends.
In order to know which operation, you have to find the keywords. EX: how many more, difference, sum, total, etc.
An additive operation is an operation which produces the sum of two operands.
To find the sum of 5 and 8, you add them together: 5 + 8 = 13. To divide this sum by 2, you perform the operation 13 ÷ 2 = 6.5. Therefore, the result of summing 5 and 8 and then dividing by 2 is 6.5.

By adding.
addition
a sum
The answer will depend on what operation you have in mind.
43. A sum is a binary operation. You have a sum of two things. There is no sense in a sum of one thing.
The sum of 8 and 4 is 12. In mathematics, addition is the operation of combining two or more numbers to find their total. In this case, when you add 8 and 4 together, you get the sum of 12.
