What does addition rule same sign mean?
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.
Why can you change the order of the addends in the commutative property?
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.
When all addends are about the same what can you use to estate their sum?
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.
What is assosiative property of addition?
You can change the grouping of the addends and the sum will stay the same
What are an addition sentence that uses the same digit for both addends and the sum?
0+0 = 0

What plus what equals 820?
The two numbers that add up to 820 are called addends. In this case, the addends are 410 and 410. When you add 410 and 410 together, you get the sum of 820. This is an example of a basic addition problem where the addends are the same number.
What is a method used to estimate a sum when all addends are close to the same value?
ÃŒn that case you can multiply one of the addends, times the number of addends.
When all addends are about the same what can you use to estate their sum?

Does sum have same prime factors as its addends?
No.
What is the sum of an odd number of negative addends?
It is a negative number. The answer is the same whether there is an odd or even number of addends.
What is the addition property for 6 plus 7 equals 7 plus 6?
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.
Does associative property state that when the grouping of addends is changed the sum is the same?
Yes, but only if it is the associative property of addition - not other versions of it.
What is it called when all the addends are close to the same number?
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.
when all addends are about the same what can you use to estimate them?
use a whole number
