Killing Aunt Sally: Unteaching Bad Math

"PEMDAS" is wrong. More importantly, it matters that it's wrong. Killing Aunt Sally peels back the covers on mathematics education in the United States. Author Jon A.S. offers criticisms of the common approaches that have been used for decades and longer, and presents a better way. From the very first numeric relationships we encountered to the last time we sat through a math class, we were likely subjected to an archaic approach that left us with the all too common, teacher-dreaded, yet completely justified question, "Why are we learning this?" But it's not too late to turn things around. Killing Aunt Sally delves into what needs fixing, how we can fix it, and why it is urgent that we do.
