Nuggets of Number Theory - A Visual Approach
                                
                                
                             
                            
                         
                            
                            
                        Contains hundreds of visual explanations of results from elementary number theory. Figurate numbers and Pythagorean triples feature prominently, but there are also proofs of Fermat's Little and Wilson's Theorems. Fibonacci and perfect numbers, Pell's equation, and continued fractions all find visual representation in this collection.
