The Khan Academy Arithmetic program will cover: addition, subtraction, multiplication, and division, of course. But we don't stop there. We'll get into negative numbers, absolute value, decimals, and fractions, too. Learning math should be fun, and we plan on having some with you.
Get up to speed on the core foundations of geometry, such as lines, angles, shapes, the coordinate plane, area & perimeter, volume & surface area, the Pythagorean theorem, and transformations, congruence, & similarity.
Learning geometry is about more than just taking your medicine, it's at the core of everything that exists-including you. Some of the specific topics that are covered include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions.
This free online Geometry course provides a comprehensive introduction to geometrical methods and techniques, covering angles, triangles, quadrilaterals, polygons, and more. It is ideal for complementing face-to-face classes, as a study guide or for those who would like to refresh their knowledge for mathematics.
This beginner's math course is an ideal introduction to fractions. The tutorial uses an interactive multimedia format and relevant examples to thoroughly examine the topic. It is ideal as a study aid or as a complement to face-to-face classes.
If you think about it, we measure almost everything: time, distance, size, weight, volume, etc. Everything can be measures. The question is, what unit of measurement is used and how is that unit constructed, compared, and converted? This last part is what is explored in these tutorials.
This is pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few.
This free online course is Pre-Algebra for high school students will guide you through several different areas of mathematics such as integers, one-step equations, inequalities and equations, graphs and functions, percent, probabilities. There is also an introduction into geometry and right triangles. The course is divided into twelve modules and each module is divided into several lessons. Under each lesson you will find theory, examples and video lessons. This course is ideal for learners who want to gain a comprehensive knowledge and understanding of topics in pre-algebra which they can build in later courses.
Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore... precalculus gives you the background for the mathematical concepts, problems, issues, and techniques that appear in calculus, including trigonometry, function, complex numbers, vectors, matrices, and other.
It covers ratio and proportion, geometric sequences, arithmetic series, difference equations, linear programming, geometry trigonometry, and graphs. This course is suitable for all math students revising for exams.
Webmath is a math-help website that generates answers to specific math questions and problems, as entered by a user, at any particular moment. The math answers are generated and displayed real-time, at the moment a web user types in their math problem and clicks 'solve.' In addition to the answers, Webmath also shows the student how to arrive at the answer.
