We think that numbers are mathemagical. Every number has a bunch of interesting properties. This Kindle book lists properties of natural numbers 300 to 399 such as factors, proper factors, sums of factors, sums of proper factors, and prime factorizations. As you browse the numbers, you will encounter prime numbers, emirps, palprimes, composite numbers, square numbers, cubic numbers, triangular numbers, factorial numbers, abundant numbers, perfect numbers, deficient numbers, and Fibonacci numbers. Grab your magic wand, mount your broomstick, and explore mathemagical numbers.
