Miscount
I have assigned a whole number to each letter of the alphabet. These numbers are not necessarily different and they include negatives and zero. With these numbers I found that
O+N+E = 1
T+W+O = 2
Advertisement
T+H+R+E+E = 3
and so on all the way up to
T+W+E+N+T+Y+N+I+N+E = 29.
Unfortunately, I now find that I made one slip in my additions. Just one of my 29 equations was wrong.
Which equation is wrong?
What should the sum of the letters equal in that case?
