minus-square@Prime_Minister_Keyes@lemm.eelinkfedilink23•7 months agoWell, on the surface, it’s just 60-3, so clearly divisible by 3 itself. Now 221, that’s some fuckery.
minus-square@Alenalda@lemmy.worldlinkfedilink4•7 months agoWhen I was young I learned that when you add up all the numbers if that number is a multiple of 3 than the original number is also divisible by 3. So 51, 5+1=6 and 6 divisible by 3 and so must 51.
