Thanks so much! So there's 49 different ways I could check the boxes? When I put it in the food example somehow that was easier on my brain and 49 was one of the answers but not the only one. It's maddening to get older and not have the math cells in your brain still working. Movie trivia, I still have ALL of that somehow! Plus "possible combination" problems can be tricky sometimes they look easy, as this was, sometimes there's 10,000 possible combinations. Wish I could pay you back, besides Thank You! smile

Mind you I am still trying to figure this out on my own but without luck. I suppose another way of putting it would be you have to eat an apple and an orange. Both the apple and the orange come in seven different varieties/flavors. How many combinations could you arrange to eat? Is that the right track?

Yep, sorry, I have a pic and wasn't sure how to attach it. Here's a direct link to my Photobucket pic -
