This puzzle has been around for many years. In that time very few people could solve it on the first try. Most
folks take several days. The engineering department of a flight simulator company in Tulsa that no longer exists
(now we know why) spent an entire morning on this quiz and eventually got all the answers.
Although we'll give you the answers on any question you can't get, once you get the right answer for an "equation"
you'll know it's right. |
