There are infinitely many possible answers:
4 + 4
or 3.9 + 4.1, 3.8 + 4.2, and so on
or 3.99 + 4.01, 3.98 + 4.02 and so on
and so on with 3, 4, and up to infinitely many decimal digits.
Or 2 + 3 + 3
and each of these can have several decimal digits.
Furthermore, the sums can extend to four, numbers: 2 + 2 + 2 + 2
or five : 1 + 1 + 2 + 2 + 2
or ten: 0.8 + 0.8 + 0.8 + 0. 8 + 0. 8 + 0.8 + 0.8 + 0.8 + 0. 8 + 0. 8
or a million and so on.

The Zero Property of Addition
8 plus 5 equals 13
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.

1/10 + 8/10 = 9/10
15 -7 = 8
The word sum is the clue. It means the problem will be an addition problem.y + 3(8) = ?y + 24 = ?
The addends in any addition sum are the numbers being added together - in this instance, 8 and 3.
To estimate the sum is to guess what the answer is for an addition problem. For example, if it was 8 + 9 you would see what number 8 is close to (like ten) and do the same with number nine and your estimate would be 20.
8
In any addition sum, such as 3 + 4 = 7, the addends, otherwise known as summands, are the numbers which are to be added together to create the sum.Addends are what you add to create the final answer (the sum). For example, in the problem 9+8=17, 9 and 8 are the addends and 17 is the sum.
The sum of b and 8 would be written b+8 or 8+b(commutative property of addition)
8 + 1 equals 9
8
commutative property of addition
If the numbers in an arithmetic problem can be rearranged to make the same result, then this is called the "commutative property" - in this case, as a multiplication sum, the commutative property of multiplication.
