From Wikipedia, the free encyclopedia
World Maths Day is an annual on-line global Maths challenge (known as World Math Day in the U.S). It is a celebration of numbers where children from across the globe are united in their aim to answer as many mental arithmetic-based questions as possible. World Maths Day takes place on the 14th of March and is also known as Pi Day because of the 3.14 in American date format. A further piece of trivia is that it happens to be the birthday of Albert Einstein.
