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.

Assignment logic problems form an important class of logic analysis problems that are generally found to be difficult. Collapsed column logic analysis technique and framework removes this inherent difficulty with a structured, systematic and efficient approach. In addition to logic puzzles and family relations problems, this powerful technique helps to solve complex reasoning class of floors problems with ease and efficiency as well...

Simple interest for a year is the percentage rate of interest applied on the initial amount invested and it is fixed year to year. On the other hand, Compound interest is the percentage rate of interest applied on the amount available at the beginning of the year, and not at the beginning of the investment period...

We find that a number of relatively difficult logic analysis problems essentially belonging to the Assignment logic analysis class are used frequently in leading Competitive exams, Interviews and other tests. In a short series of sessions we will cover this important class of logic analysis problems...

Law of sines and cosines relate side with sine and cosine of an angle opposite the side in triangle. By sine law, ratios of side to sine of angle are equal.

Trigonometry first established relationships between the angle and side measurements of a right angled triangle by defining trigonometric functions and thus extended the reach of mathematics wonderfully. Like any other branch of mathematics, from the basic trigonometric function definitions more advanced function relations are built stage by stage. Here we will deal with compound angle trigonometric function relations in more details...

Relation between median and sides of triangle: Sum of two sides is larger than the median from common vertex and three times sum of squares of length of sides equals four times the squares of medians of a triangle.
