In work life and personal life often we need to learn the basics on a subject quickly. Usually it is not easy to acquire the basic concepts on any subject reliably in a short time from a concise material.

Basic concepts on any subject form the foundation, but generally we have found it is not easy to build it in a short time. Our focus here is on base concepts in a concise form that can be learned quickly and be used as a launch pad for further learning and subject specific problem solving.

Often we added a rich concept layer derived from the base concepts that helps to solve more complex problems with great ease. For us, it is a two layer concept model: Base concepts and Rich concepts derived from base concepts. Objective is efficient problem solving.

How to solve Surds part 1, Rationalization

thumb_how-to-solve-surds-part-1-rationalization

Surds are a special group of irrational numbers that can be represented easily in compact form as $\sqrt{2}$, $\sqrt{3}$ etc. In addition, a number of quick math methods in simplifying surd problems make this topic a favored one for testing problem solving abilities in schools and competitive tests...

Basic and rich concepts on Moving Escalator to solve difficult Speed Time and distance problems in a few steps

thumb_escalator time distance problems

Usually time and distance problems involve objects moving on fixed stationary ground base. When the base starts moving, an additional level of complexity is introduced. These are problem areas favorable for applying very basic relative speed concepts and arrive at solution in a few steps...
