Roland "Ron" Edwin Larson (born October 31, 1941) is a professor of mathematics at Penn State Erie, The Behrend College, Pennsylvania. [1] He is best known for being the author of a series of widely used mathematics textbooks ranging from middle school through the second year of college.
The Saxon Math 1 to Algebra 1/2 (the equivalent of a Pre-Algebra book) curriculum [3] is designed so that students complete assorted mental math problems, learn a new mathematical concept, practice problems relating to that lesson, and solve a variety of problems. Daily practice problems include relevant questions from the current day's lesson ...
The 2003 edition makes reference to computer software such as The Geometer's Sketchpad. [1]: p. 3 Even before this edition, the Teacher's notes for Geometry was used for developing new ways of teaching. [9] [10] One instructor credited the book's success to being "mathematically very sound" yet using a "little by little" approach. [11]
The Curta was conceived by Curt Herzstark in the 1930s in Vienna, Austria.By 1938, he had filed a key patent, covering his complemented stepped drum. [3] [4] This single drum replaced the multiple drums, typically around 10 or so, of contemporary calculators, and it enabled not only addition, but subtraction through nines complement math, essentially subtracting by adding.
Charles Royal Johnson (born January 28, 1948) is an American mathematician specializing in linear algebra. He was a Class of 1961 professor of mathematics at College of William and Mary . [ 1 ] The books Matrix Analysis and Topics in Matrix Analysis , co-written by him with Roger Horn , are standard texts in advanced linear algebra.
Core-Plus Mathematics, CCSS Edition. Core-Plus Mathematics is a high school mathematics program consisting of a four-year series of print and digital student textbooks and supporting materials for teachers, developed by the Core-Plus Mathematics Project (CPMP) at Western Michigan University, with funding from the National Science Foundation ...
Shortly before her death in 1985, Dolciani also co-wrote (along with two other mathematics educators) Pre-Algebra: An Accelerated Course. This textbook was widely used in the later 1980s through the 1990s. In addition to teaching the pure mathematics, it emphasized the usefulness of algebra in various practical applications.
The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations .
