Congratulations on a great school year, guys. Jeremi, before you outsource all calculations to a computer, please take a look at the Trachtenberg method which we learned about when I attended Davidson Middle School all those years ago. It was invented by an engineer while he was in a Nazi concentration camp; he had to do all the figuring in his head because he had no pen and paper. For example, to multiply 43 times 11, add the digits 4+3 =7 and then place the sum between the two digits: 473. Amazing. You never know when you might be in the wilderness with no computer!
