A mathematical (sort of) puzzle to help you while away your lunchbreak. I haven’t worked out the answer yet myself, so if you beat me to it, you can have at least one kudo, maybe more.
ELEVEN + THREE THREE ONE ONE ONE ______ TWENTY
Each letter has a numerical value from 0-9 (no two letters can have the same value)
We are told that:
E is either 1,3,5,7
O is not 0
T is not 0
Go for it! (And no sneaky writing a program to solve it exhaustively [unless that turns out to be the only way…].)
