Frequent Questions about our Solver
can you explain how the 247 came about
Answer provided by our tutors
It is a numeric expression, '9' is subtracted from 16^2 which is the equivalent to 2^8 and equal to 256... hence, 247+9=256 and 256-9=247.
Perhaps we are missing something about the observation... our solver will default to prime numbers, hence 16^2 was expressed as 2^8.
