ok so this is a little hard
umm... the 10th Prime number is
let's see:
1,2,3,5,7,11,13,17,19,23 <------ 23
And the 10th composite number is:
4,6,8,9,10,12,14,15,16,18<------- 18
SO 23 plus 18 ISSSSSS........... 41
So the sum of the 10th prime number and the 10th composite number is 41!!!

1 is neither prime nor composite. So the tenth prime is actually 29 and the sum is 47.
