excel

I did learn a lot of new things about excel that I didn't even know were possible. As a principal, I would at least make sure all the software on every computer in my building was EXACTLY the same because noticing all the problems we had in our classroom today with smart people working on nice computers, I cannot imagine how frustrating it must be to teach computer applications to kids working with poor equipment. I really don't see a school being very successful if they are working with many different versions of a program like excel simultaneously.
