As a school student one is always expected to learn the three R's – reading, writing and arithmetic. Almost all people begin to develop a sense of arithmetic in their childhood. Yes, believe me – very few people suffer from dyscalculia , a condition in which the patient has difficulty in understanding numbers and their manipulations.

I have been associated with Mathematics Olympiads since 2011. I try helping students with olympiad related problems. During the lockdown of 2020, I had made several lecture videos for students aspiring for olympiads. These are avaiable in my YouTube Channel.
