Pure Numbers Daily Blog

Fun mathematical facts about today's date! I use a range of math operations and tools including (but not limited to), arithmetic, exponents, geometry, factorials, different number base systems, trigonometry, combinations and permutations. I welcome submissions that add onto today's date or suggest an idea for a future date. Enjoy!
