## Math Puzzles and Logic for All Ages

At first glance, math and logic based puzzles and games may seem only suited to mathematicians. Although mathematical logic may require some knowledge of mathematical principles or operations, it also relies on reasoning and deduction – the core focus of logic. Philosophy has studied and debated the basic principles of logic for thousands of years. Math logic eventually evolved with the goal of eliminating inconsistences and contradictions associated with informal reasoning. Today math logic problems and games are useful for learning new facts, thinking in new ways, and increasing cognitive abilities. Due to their fun, deceptively simple nature, and because they rarely require deep mathematical knowledge, logic problems and puzzles have become a popular pastime and are increasingly being developed in new and different ways. The math and logic problems presented here include word problems, nanograms, number problems, brainteasers, and more. Problems are suitable for all ages and abilities.
