I picked up a coffee cup the other day, because I like the equation on it!
Here's a picture of it:
How do you like it?
The square root of a negative one is symbolized by the letter i for an imaginary number.
2 cubed is eight.
Sigma in math is sum.
The Greek letter Pi in this case stands for pie!
So I have the sentence:
I 8 sum pi...or I ate some pie! Followed by; and it was delicious.
I just had to have it, ROFLOL! In case I run across some pi....
