The sum of a set of addends whose sign is the same is the sum of the absolute values of the addends with the same sign as the addends.
This is possible because the order of the addends does not matter. For example, 3+8 is the same as 8+3. No matter how you list the addends, the sum will always be the same.
If all addends are the same, or very near the same, you can take one of the addends and multiply it by the number of addends that exist, and you have the sum. For example: 100 + 101 + 99 + 102 + 100 + 103 + 98 = ? In this case, all addends are close to 100, and there are 7 of them. So, you can approximate the sum by saying: 100 * 7 ...which is 700.
You can change the grouping of the addends and the sum will stay the same

ÃŒn that case you can multiply one of the addends, times the number of addends.

No.
It is a negative number. The answer is the same whether there is an odd or even number of addends.
the addition property for 6 plus 7 equals 7 plus 6 is the commutative property. This property states that - when two numbers are added, the sum is the same regardless of the order of the addends.
Yes, but only if it is the associative property of addition - not other versions of it.
When all the addends in a sum are close to the same number, it is called "rounding." Rounding helps simplify calculations and provide a quick estimate of the total.
