Airehead Posted October 29, 2020 Share #1 Posted October 29, 2020 For me probably. Please excuse my dear Aunt Sally. Mostly because it can be wrong. The problem with PEMDAS is that it excludes the "from left to right" requirement for multiplication and division (#3 below) and addition and subtraction (#4 below). Students, as a result, think multiplication always precedes division and addition always precedes subtraction. This explains why students in the above example said 4 - 2 + 1 equals 1 rather than 3 (i.e., they simplified 2 + 1 first rather than 4 - 2).

shootingstar Posted October 29, 2020 Share #37 Posted October 29, 2020 American Jurisprudence 2d..is an encyclopedic digest that's online and covers principles of American law with citations to key court cases. All areas: constitutional, civil, criminal and administrative law. Black's Law Dictionary is the premiere law dictionary in the English language world. As you may know the Oxford English Dictionary....online is beyond its original 12 volume set on etymology of word..definitions with examples of use. Yes, British spelling is preferred in that volume. It is the scholary dictionary if studying in English literature at college/university..all eras: medieval and onward. It is incredible to see the history of a word and if it has changed in meaning /spelling over the centuries. I did recommend each of the 2 above for researchers... judges and lawyers do quote from those sources. 1 Link to comment Share on other sites More sharing options...

In Kyoto we found a 900 yr. Shinto shrine inside a Buddhist temple compound area. When I was there, I was confused...and later found out, why I was.It was Buddhist site, which got taken over by Shinto worshippers. Kinda like a Catholic church that might have Islamic artistic decorations...in certain parts of Spain. 1 Link to comment Share on other sites More sharing options...
