13 and 7
2+3=5
The three prime addends that sum to 21 are 5, 7, and 9. However, since 9 is not a prime number, we can express 21 as the sum of three prime numbers in other ways, such as 3, 7, and 11. Another combination is 3, 5, and 13. Thus, there are multiple combinations of prime addends that can equal 21.
The sum of 54 and 63 is 117. This can be expressed as the product of 9 and 13, where 9 and 13 are relatively prime addends. Therefore, 54 + 63 = 9 × 13.
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.
Addends.
ÃŒn that case you can multiply one of the addends, times the number of 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.
The sum could be anything, but it would be a positive number if the two addends are positive.
