Find the additive invers of -9 on the 12-hour clock?
For Noon (12:00PM) as the starting point: The additive inverse of -9 hours behind is +9 hours ahead or 9:00PM For Midnight (12:00AM) as the starting point: The additive inverse of -9 hours behind is +9 hours ahead or 9:00AM It depends on where you want to start.
Well!!!!!! In a 12 hour clock, 12 is equivalent to zero Now, If you have any number A and if its additive inverse is B, then, A + B 0 Here, - 9 + B 0 Here 0 may be 12 also!! - 9 + B 0 or 12 Thus, B 9 or -3
