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.
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.
multiplication
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.
Addends are the numbers that are combined to create a sum. For the sum of 50, any pair of numbers that, when added together, equals 50 can be considered addends. For example, 20 and 30, or 25 and 25 are both sets of addends that sum to 50. There are infinitely many combinations of addends that can achieve this sum.
You can change the grouping of the addends and the sum will stay the same
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.
ÃŒn that case you can multiply one of the addends, times the number of addends.
No.
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.
i am a sum. my addends are five different whole numbers. all my addends are greater than zero and less than eleven. all my addends are odd numbers. what am i?
you can use whole numbers
multiplication
Mutltiply that "same" number by the number of data points.
It is a negative number. The answer is the same whether there is an odd or even number of 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.
That's the mean (average) of all the addends.
