Now ever since Pythagoras, and indeed even before, math and music have been intimately linked. Yet in modern times we seem to have forgotten that. Well, here are some rappers bringing back the math... old school style.

Mathimoto's Real Complaint
My real complaint is I haven't been able to post more.
Alack, alack, alack. And the real victims are you good folk. But even Mathimoto needs a job, and rest assured once the job situation is stabilized, posts will come once more!!!
But in lack of that, let me give you a little play with number, related by the way, to some secret math speculation I'm doing.
If you want to find if a number is divisible by:
2, check if it's even. (Simple enough)
3, add all the digits and see if the sum is divisible by 3, if it is then the actual number is divisible by 3. (That's one of the cooler tricks)
4, if the last two digits are divisible by 4, then the whole thing is divisible by 4.
9, add the digits, and if the sum is divisible by 9, then the actual number is divisible by 9.
Do you see the suggestion here? Maybe there's a relation between numbers and their base 10-representation. Maybe... and maybe I'm getting close to it... maybe...
But what we do know for sure (to quote my good friend Kendrick), is that numbers are awesome.
NUMBERS RULE!!!!!!!!!
WOOOOO!!!!!!!!

Let me hear you say math... MATH!!!
A friend of mine once noted that it's a shame that math theory is becoming too complicated for normal people to play with.
But I don't think that it's a necessity, I think mathematicians just accept that this is the way the world must be, and thus refuse to take any effort to simplify mathematical theory.
And perhaps more importantly, new areas in math theory which might be more accessible to amateur innovation aren't being explored as vigorously as they should, largely because mathematicians are starting to forget what math is really about...
Playing with numbers.
Because numbers rock.
In that spirit, look at a list of squares
1
4
9
16
25
...
If you look at the differences between consecutive squares, you'll see a pattern and if you play with that pattern a little, you get...
n^2 = Sum from i=1 to n (2i - 1).
Think about it...
