Mathematics Stories: Given tough x-intercepts, finding the VERTEX of a PARABOLA
For years and years of teaching advanced mathematics, I always just found the vertex of a parabola by completing the square. In challenging top end students, I'd give them "raunchy" x-intercepts and have them find the vertex. I taught the algorithm in this product, and figured that every textbook would do the same. I used to have dozens of old Algebra 2 and Pre-Calculus textbooks. The step by step procedure was not in any of them. I hope that all of you who teach HONORS level mathematics will

Mathematics Stories - HAPPY HARRY
Mathematics Stories - HAPPY HARRY - was one of my more "radical" stories. Dividing Fractions and Simplifying Rational Expressions by division are tough for students at different levels of mathematics. I have always "inverted and multiplied" in my head. By the way, the proof of why we have to invert before we multiply (because you want to divide by 1, is too long to really explain, so we tell students ... ) That is the only "formal" algorithm that mathematicians know. Since I always did this in m
