I have always enjoyed this holiday mathematical take on "HO HO HO" for the holidays! Without a doubt, it is a great boost for the holiday spirit and for creating a positive mathematical environment for our students. I once showed it to my department chair who immediately corrected me saying that I should put parentheses around the "HO" to be "mathematically correct". He was absolutely correct, so please note, the parentheses are included....:)
Please enjoy, and Happy Holidays to you and yours from me.
PS: if unclear as to the meaning, it means HO to the third power; in other words, HO HO HO. Just a little math humor...:)
