## Art of Problem Solving – Conversation with a Student

Question Asked by a Student:- A 2 by 2 determinant is chosen such that the elements are from the set {-1, 1}. Find the probability of choosing determinants whose value is 0? Solution:- Based on DoPrep’s method of problem solving strongly influenced by the works of the great Hungarian Mathematician George Pólya. The following conversation between the student and DoPrep illustrates […]

## “How to Solve …” – The Art of Problem Solving It has been noted over the years that most of the students who fail to clear a competitive entrance test like JEE, BITSAT etc. fail to understand the underlying thought process of “How to Solve” a particular question in the first place. The most common practice followed by the students while solving a question is Start answering the question immediately Try to […]
