The answer has to do with how many circles are in each number. So the number 8 has two circles in its shape(well..should say, count the eggs in each number..lol) so it counts as two(eggs). And 0 is one big circle, so it counts as 1. So 2581=2. Ok, that’s cute, it’s an alternative mapping of values with implied addition.
