Cupcakes With a Twist

Danielle had Strep Throat earlier this week, so Brad and I took turns tag-teaming who stayed home during the time she needed for her antibiotics to take effect.  I was talking with her about school and looking through some of her homework papers...she is a very artistic child and her mind is so interesting to me sometimes.  I caught one answer that has made me laugh for a few days.  Danielle is in 3rd grade now and she is starting into some story problems for her math class.  So, there was a problem....let's say it said, "Danielle was having a party and invited a bunch of friends.  She took 15 cupcakes to the party and all her friends ate one.  She ended up with 2 cupcakes left over.  How many friends did she invite to her party?"  Actually, I really like that one....it has an added twist, BUT ANYWAY....then the question said, "How would you solve this?"  They meant for her to write out the equation she would use....like 15-2=13 people at the party-1 (Danielle)=12 friends....see I made that one too hard :)  BUT, Danielle wrote...."I would use my brain." in the space they provided her :)
