How to solve Time and Distance problems in a few simple steps 1

thumb_How to solve time and distance problems in a few simple steps 1

Time and distance problems are taught in middle schools and also form an important component in competitive tests. In any case, our endeavor is to solve such problems elegantly in a few simple steps in contrast to generally complex and time consuming conventional approach to solving such problems...

How to solve more Time and Work problems in simpler steps, type 2

thumb_How to solve time work problems in simpler steps type2

In a large number of math problems involving Time & Work, it is stated that certain number of men take certain number of days to complete the work. These problems are usually solved in conventional methods by using per day work rate of 1 man. Instead, the number of days and number of men can be combined into a single powerful measure of work amount, simplifying the process greatly...

How to solve Time and Work problems in simpler steps, type 1

thumb_How to solve time work problems in simpler steps type1

To solve math problems involving Time & Work, it is usually assumed that a work-agent takes certain number of time units to complete the work alone. This immediately forces the use of inverse of the variables corresponding to each work-agent. Instead, adopt conceptually and psychologically a much simpler approach...

How to solve a School Math problem in a few simple steps, Trigonometry 2

thumb_How to solve a school math problem in a few simple steps Trigonometry 2

The conventional approach to math problem solving relies heavily on manipulation of terms using low level mathematical constructs without using the problem solving abilities of the student. Following only this approach to solving problems, students may tend to become used to mechanical and procedural thinking suppressing their inherent creative and innovative out-of-the-box thinking abilities...

The mechanical approach to math problem solving relies heavily on manipulation of terms using low level mathematical constructs without using the problem solving abilities of the student. In fact, if students follow only this approach of solving problems, they may tend to become used to mechanical and procedural thinking suppressing their inherent creative and innovative out-of-the-box thinking abilities...

Base equalization technique is indispensable for solving fraction problems

thumb Base equalization technique in fraction problems

Base equalization technique produces quick solutions in indices problems. But that is not the only area of application of this more general concept. For solving problems on fractions also, the base equalization technique is indispensable...

Permutation and combination

thumb_permutation and combination

Permutation and combination deal with choice and arrangement of a set of objects out of a second set of objects. Permutation deals with such questions as, how many ways can the three letters a, b and c be arranged? In each such permutation or arrangement, ordering is important. On the other hand, Combination deals with such questions as, how many ways can you choose a captain and vice-captain out of a cricket team of 11 players? In a combination, ordering of the elements chosen is not important...

Numbers, Number System and basic arithmetic operations

thumb_Number system

Numbers form the very foundation of Mathematics whereas zero and place value mechanism together make it possible to form any number, however large or small it may be. After formation of numbers, the four basic arithmetic operations addition, subtraction, multiplication and division transform the numbers using again place value system as a base mechanism. On this foundation Mathematics grows further..
