Beyond Four Walls — Contain a mathematician in a room and you can be sure that some thinking on quadrilaterals will happen! Our second issue during the pandemic has much to keep you absorbed and happily engaged with problems- of the mathematical kind. From age digit reversals to an algorithm for evacuating a room — there is material for every age group. We begin with the all important question: Why Should You Study Mathematics? And we also carry a review of the Classes I‑III Sikkim Mathematics Textbooks, the development of which our URC-PDP played such a key role in.
