2+3=5
No.
It is a negative number. The answer is the same whether there is an odd or even number of addends.
in the equation 3+4=7, 3 and 4 are the addends. 7 is the sum.
ÃŒn that case you can multiply one of the addends, times the number of addends.
Addends.
That's the mean (average) of all the addends.
The sum of a set of numbers divided by the number of addends is the mean average of that set.
2, 5, 5
The sum could be anything, but it would be a positive number if the two addends are positive.
0.4% of 20 = 0.4% * 20 = 0.004 * 20 = 0.08
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.
