Dak's number is 15. If you add the numbers in 15 1+5 you get six.
This is much better than Tyler Russell's number 17, which basically meant *******.
If 1+5 = 6, then the 6th letter of the alphabet is F.
If you add 15 to 6, you get 21, and the 21st letter is U.
If you multiply 5 times 1, you get 5, and if you divide 15 by 5, you get 3. The third letter of the alphabet is C.
If you subtract 1 from 5, you get 4, and if you subtract 4 from 15, you get 11, and the 11th letter of the alphabet is K.
Put those 4 letters together, and you spell out 17.
So, you're back to square one. 15 = 17...Dak = Tyler Russell
