minus-squarevortic@lemmy.worldlinkfedilinkarrow-up44·edit-21 year agoI’d forgotten this trick. It works for large numbers too. 122,300,223÷3 = 40,766, 741 1+2+2+3+2+2+3 = 15
minus-squareFlexibleToast@lemmy.worldlinkfedilinkarrow-up25·1 year agoThe neat part is that if you add the numbers together and they’re still too large to tell, you can do it again. In your example, you get 15. If you do it again, you get 6, which isn’t the best example because 15 is pretty obvious, but it works.
minus-squarepostmateDumbass@lemmy.worldlinkfedilinkarrow-up2·1 year agoProve it for 2, then un-distribute.
minus-squareRodeo@lemmy.calinkfedilinkarrow-up2·1 year agoThere is a mathematical proof that 1 + 1 = 2 so surely you could make a proof for 6 ÷ 3 = 2

122,300,223÷3 = 40,766, 741
1+2+2+3+2+2+3 = 15
threw up and died while reading this
I wish I could read 😞
Just squint and wing it.
That is way too accurate. Lol
Also works with 9s!

But how do I prove it for 6
Get 6 apples. Duh.
