laughter is the best medicine

Please Excuse My Dear Aunt Sally Shirts

 

what made me laugh even further was learning what it actually meant …. I’ve always had this crazy love of math – not applied math and especially not physics or economics but pure math? algebra? calculus?  learning how to derive all those little formulas we had to memorize in geometry, was the coolest thing ever and the only exam at Northwestern, I ever aced.

so

please excuse my aunt sally:

mnemonic for the order of operations in math:

parenthesis, exponentiation, multiplication, division, addition, subtraction

Multi layers of meaning ?  It doesn’t get much better! Being Aunty Sally? Is the best in all ways and layers possible!
