The BAWP was established in 1974 by James Grey at the University of California, Berkeley. [4] The CMP was created in 1982 by legislative act SB 424 (Carpenter) to "seek to solve the mathematics skills problem of students in California through cooperatively planned and funded efforts." [5] At that time nine sites were funded throughout the state.
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.
The California Standards Tests (CSTs) are designed to match the state's academic content standards for each grade. Grades 2 through 8 tests cover mathematics and English/language arts (which includes writing in grades 4 and 7). Grades 9 through 11 cover English/language arts, mathematics, and science.
Project Mathematics! (stylized as Project MATHEMATICS!), is a series of educational video modules and accompanying workbooks for teachers, developed at the California Institute of Technology to help teach basic principles of mathematics to high school students. [1] In 2017, the entire series of videos was made available on YouTube.
It has a compatibility mode with Maple, Derive and MuPAD software and TI-89, TI-92 and Voyage 200 calculators. The system was chosen by Hewlett-Packard as the CAS for their HP Prime calculator, which utilizes the Giac/Xcas 1.1.2 engine under a dual-license scheme.
A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was created by Charles Babbage . The name difference engine is derived from the method of finite differences , a way to interpolate or tabulate functions by using a small set of polynomial co-efficients.

Harold R. Jacobs (born 1939), who authored three mathematics books, both taught the subject and taught those who teach it. [1] Since retiring he has continued writing articles, and as of 2012 had lectured "at more than 200" math conferences. His books have been used by some homeschoolers [2] and has inspired followup works.
