Uhm, lol that's like the most complicated equation ever for converting binary to decimal. I suppose it's cool because it works with any base, but it's kind of useless to memorize that complex series summation when you could probably do the conversion faster using simpler methods to a certain amount of digits. This would be pretty useful for a program to do base conversions though 
Oh, and for those that are confuzled by that, it's sigma notation for a series, in this case a sum of a series. Not sure when you usually learn series, but we learned them in our Algebra II class, however we were working in Advanced Algebra. So I suppose it's either an Algebra II or Advanced Algebra concept. Basically all it is saying is to plug in i and increment until n is reached and add up all of those sums. You plug in 1, solve, plug in 2, solve, etc and add up all of the solutions.
