I just found this out so I figured I'd pass it along. Many of you probably already know this. When you are figuring a problem on ALEK's w/a lot of numbers, you can highlight the numbers on the screen and hit the Sum button on the calculator which gives you a total in the calculator. Speeds up the process tremendously. You can also get a standard deviation by highlighting the numbers and hitting the S button. I should have learned this a long time ago. This is where a bit of my time went. Maybe this will save some of you time.
