My nephew gave me this great math funny comic so of course I had to share!
I also thought it would be good to share links about imaginary numbers in case you do not recall them.
You might think that this stuff is hardly used, but I was chatting with a friend the other day who told me about the old days of using Pythagoras to calculate touch screen inputs on cell phones and the app that was required to be made for a job interview at a tech company. It is pretty amazing how much math is all around us... Imagine that!
