To mark the announcement by IBM CEO Ginni Rometty about a new era of cognitive computing (http://www.ibm.com/cognitive/outthink/), this month's Ponder This challenges you to create a uniquely solvable verbal arithmetic equation (https://en.wikipedia.org/wiki/Verbal_arithmetic) using English words, whose result is WATSON, and which is composed of only these six letters.
Here are some (wrong) examples:
- TATTOO-NOT=WATSON - insolvable
- NOT*SON+ON*ANTON=WATSON - the only solution is invalid since it contains a leading zero in "ANTON"
Remember that different letter must have different numerical value.
We will post the names of those who submit a correct, original solution! If you don't want your name posted then please include such a statement in your submission!
We invite visitors to our website to submit an elegant solution. Send your submission to the ponder@il.ibm.com.
