Here's a special one for you!




I am prime, I am composite



Sum my digits and half; I'll be perfect!



Don't multiply them, I won't yield a thing



But don't worry, it's only the beginning!




What am I?

          Hoping this is good




          $2019$




          I am prime, I am composite




          Prime as in beginning and composite as $2019 = 3cdot673$




          Sum my digits and half; I'll be perfect!




          $2 + 0 + 1 + 9 = 12$, then $12/2 = 6$




          Don't multiply them, I won't yield a thing




          $2 cdot 0 cdot 1 cdot 9 = 0$




          But don't worry, it's only the beginning!

          I'm thinking it might be




          $39$

          $(3+9)/2=6$, a perfect number as its factors sum to the number itself: $1+2+3=6$

          $3$ is prime and $9$ is composite


          Multiplying them won't yield just a thing, it yields $3times 9=27$ things


          I am a bit hung up on this but perhaps $39$ is the beginning of a sequence where these rules hold true (i.e., it's the smallest number produced by these rules). Or perhaps it's the first two of this series: $3^1, 3^2, 3^3, cdots$

          1?

          Some say 1 is prime, some say it is composite

          ? Perfect number?




          Don't multiply them, I won't yield a thing
