that was not a brain teaser it was a question in math class
I haven't been to a math class in years but hey, what teases the brain more than math?
Hey that was a great idea but way too hard without some hint at least to the form of it.
My apologies Jimbo. I'm new at this. Next time I shall try to add a hint.
