minus-squareSockenklaus@sh.itjust.workslinkfedilinkarrow-up3·1 year agoYou clearly mean: 14: 1 + 8 = 9 (not db 7) Someone else in this thread correctly stated: “Chop of last digit, double it and subtract from what is left” 14: 1 - 8 = -7. (dB 7!) Math is awesome, I didn’t know this trick!

14: 1 + 8 = 7. Not db7
