This study skills survey is designed to help you review your current study habits and perhaps learn new ones.

Basic reference tables on numeracy, algebra, etc,

math test activities for students and teachers of all levels.

from Lumen

"d. The student will begin this course by reviewing basic set theory, integers, and functions in order to understand how algebraic operations arise and are used"

"The student will also take a look at ring factorization, general lattices, and vector spaces. Later this course presents more advanced topics, such as Galois theory - one of the most important theories in algebra"

"...this course, the main focus is on five types of functions: linear, polynomial, rational, exponential, and logarithmic. In accompaniment with these functions, you will learn how to solve equations and inequalities, graph, find domains and ranges, combine functions, and solve a multitude of real-world applications."

Math simulations for all levels from the University of Colorado Boulder

"The purpose of this course is to expose you to the wider world of mathematical thinking. There are two reasons for this. First, for you to understand the power of quantitative thinking and the power of numbers in solving and dealing with real world scenarios. Secondly, for you to understand that there is more to mathematics then expressions and equations."

MyOpenMath runs on the open source, IMathAS platform, providing free hosted use of this platform in support of free, open textbooks like the ones listed on OpenTextBookStore.com. The intent is to provide classroom use of the platform, without any required cost to students, for schools wanting a managed install of the IMathAS platform, and to provide students self-study opportunities.
