It's often easier to perform the sum in the other order due to the associative and commutative properties of addition, which allow for flexible grouping and rearrangement of terms. This can simplify the calculation, especially when dealing with large numbers or fractions. Additionally, changing the order may help in identifying patterns or combining like terms more efficiently. Ultimately, reordering can lead to a more straightforward or intuitive approach to solving the problem.
What else can I help you with?
What is the sum of -3 and 7?
Probably easier to think of this the other way around as: 7 - 3 = 4.
What is the sum of 2 and the product of 9?
These numbers have to be multiplied/added by other numbers in order to get other numbers. Otherwise I assume you mean the sum of 2+0 which is 2, and the product of 9x1 which would be 9.
The sum of a positive integer and a negative integer is always sometimes or never zero?
If the integers are the same, then the sum is always zero.If the integers are different, then the sum is never zero.If there's no rule governing the choice of integers, then the sum is sometimes zero.By the way . . . we're talking about 'integers', not 'intergers'.
Can a subtraction problem can be called a sum?
No, the answer in a subtraction problem is the difference.
Is it true that the sum of two even number is sometimes odd?
No it isn't true.

Is it possible to build a triangle with 9 7 and 16 side lengths?
> No. One side must be greater than the sum of the other two. Actually, each side must be shorter than the sum of the other two in order to build a triangle. In this case, the side of length 16 is not shorter than the sum of the other two sides.
At the end of a movie when the credits are rolling the first person's name that appear first does that mean they were the highest paid.?
Usually. Exceptions: Sometimes the cast is listed in ABC order. Sometimes a big star will be paid a huge sum for a small role.
Is the sum of two rational numbers sometimes zero?
Yes.
Can a subtraction problem can be called a sum?
No, the answer in a subtraction problem is the difference.
The sum of zero and a negative integer is always sometimes or never zero?
The sum of zero and a negative integer can never be zero - it will always be negative and nonzero. Although zero is also an integer, it is neither negative nor positive and cannot be the other integer used.
Is the sum of positive and negative integers sometimes positive yes or no?
Yes. But NOT always.
Is it true that the sum of two even number is sometimes odd?
No it isn't true.
Is it sometimes true when the sum of two rational numbers are rational?
No, it is always true
Is the sum of zero and positive number always sometimes or never zero?
Never.
