What is the secret number if it is greater than 25 and less than 50 and the tens digit is an odd number and the sums of the digits is less than 10?
Could be 31, 33 or 35...
If you pair each of the numbers from 1 through 8 so that the sum of each pair are identical what would the sums be?
9
What two square numbers total 21?
There is no pair of perfect squares that sums to 21. And the question is pointless if it is not about perfect squares because in that case there are infinitely many answers.There is no pair of perfect squares that sums to 21.

Which is the only number which is equal to the sum of its digits?
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.
How is the mean calculated?
Add all the sums, then divide by the number of sums. (ie. the average.)
Sums number then divides by the number of values?
Average Function
What are sums or pairs?
I'm not sure what you are asking. Sums represent either an increase of one quantity by another quantity, or a combination of two quantities. Two of anything is a pair. Did you mean to ask, "What are sums of pairs?" One common use of a pair in mathematics is an ordered pair, such as (2,3). This can represent a coordinate in a graph, or it can represent a vector. If pairs represent a vector, you add the components, so (2,3) + (40,50) = (42, 53).
What is to different pairs of decimals whose sums are 14.1 one pair should involve regrouping on math?
The two different pairs of decimals whose sums are 14.1 and one pair involves regrouping on math are 8.4 and 5.7.
How many sums equal 25?
An infinite number.
Is the number 21 abundant or deficient or perfect?
It is deficient: It's only proper divisors are 1, 3, and 7, which sums to 11, which is less than 21.
