To the tune of "Jingle Bells":
A day or two ago, I tried to solve for c
when all the time, you know, I should have solved for b.
But after many tries and sessions after school
I uttered loud and joyful cries when I found out this rule:
Ooh - a and b, b and c, write them on the page,
sometimes put down x and y, they seem to be the rage.
Don't give up - play it cool - make a guess or two
And keep the paper neat and clean and there's a pass for you.
(Origin: unknown)
The song is about a student who is struggling with a math class, and decides that it will be enough to write some symbols (x,y,a,b) on the paper, and, as long as it looks neat, the homework will be accepted...
