This took some logic, but was easy once I realized that A and D depend only on each other.
It was pretty hard to find out if it should go in Logic or Math.
I liked it! Took me a little to find D but then it was easy.
pretty hard, but fun!!
Definitely a math problem, and a decent one at that, but that does not make it a teaser.
Good and fun, and extremely easy. Why would this NOT go in Math?
