Math ... dead? Noooo hhhhh.
So back in the days of SchoolHouse Rock, and multiplication rock, when you could get some basic math music while watching saturday morning cartoons, there was a rabbit named "lucky seven sampson". And one of his lines was something like, "Multiply 7 times 4? That's 28 days and-a one month more, to pay back the mortgage on your store".
Hence, the math theme.
Now, I could do something as unoriginal as 2*2*11. But ...
7*6 + 5 - 4 + 3 - 2*1
(and it's an alternating sum).
EDIT: Foo, no, the first two terms are positive.
8*7 - 5*4 + 3*2 ... nope
9*8 - 7*6 + 5*4 - 3*2*1
72 - 42 = 30 + 20=50 - 6 = 44
