Numerology challenge number 8 or 1

[joker]

If I - 8-16 my challenge number would be 8, but by rule I would bring down, 8-7 would equal 1 which do you think is right 1 or 8 hm?

my friend you have  four challenge numbers coming from your date of birth  remember to reduce when finding these numbers and focus on the challenge  at hand  .overlooking the present can have negative effects in the future  you must also look at your third challenge for it will remain a constant energy vibration though out your life time
