That's what I was thinking. Any kid who can figure out that (1) a key combination will perform a function and (2) the results would be accurate in not getting any kind of "unfair" advantage at all, unless we use the Left's definition of "unfair" as being any ability not possessed by the stupidest among us.

Yeah. This reminds me a bit of when I was in college, and took finite math, we had to learn matricies. To this day, I'm really not sure what they are good for, but I remember that in order to do functions longhand, it was tremendously time-consuming for us intro to finite math folks (maybe somemore more proficient could go a lot faster). Anyhow, I had a TI-81, I think it was, approved by the course, and I discovered it had a matrix function in which I could perform all the necessary functions. Our exam was slotted for two hours, I turned my test in in 10 minutes, and the professor looked dumbfounded. Asked me if I was sure I wanted to turn it in, I said yep, and left. I don't think he knew the calculator could perform those functions (because I doubt he would have let us use it on the exam), so I don't know what he thought about me--maybe that I was some sort of super genius or a cheater or what. I have no idea.

They are good for simplifying linear equations. Linear equations are useful for simplifying differential equations. And differential equations are helpful for studying or designing dynamic systems that bounce, spring, spin, flutter, and oscillate. They are also used to simplify the dfqs used in heat, fluid, and shear flow.

They also make good motion picture vehicles for Keanu Reeves.

Matrices are great for solving simultaneous equations with multiple variable. Very time consuming the long way.
