multiplication
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.
an estimating technique in which the front digits of the addends are added and then the sum is adjusted for a closer estimate
Hm well you can use whole numbers. Now my boy do you get it? Get that brain working!
ÃŒn that case you can multiply one of the addends, times the number of addends.
you can use whole numbers
multiplication
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.
Mutltiply that "same" number by the number of data points.

No.
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?
It is a negative number. The answer is the same whether there is an odd or even number of addends.
