I believe that it was the German mathematician Carl Friedrich Gauss who said that "Mathematics is the queen of the sciences—and number theory is the queen of mathematics." If you're not sure what a number theorist is, I will tell you now. Number theorists study prime numbers as well as the properties of objects made out of integers or defined as generalisations of the integers. It used to be called arithmetic back in the early part of the 20th Century but, over the years, that term has been stretched to cover several other different forms of mathematics. 

There you go. I'm betting that there aren't many readers out there that knew that. Not being a math wizard, I certainly didn't.  So, what's that got to do with the app that we are reviewing today? Well, the MetaNumbers app is a free mathematical tool that delivers detailed information about any positive natural number. Actually, that's not quite true because the highest number it will provide information on is 9223372036854775807 but that could be called splitting hairs by some. 

So, what is a prime number? Well, it's a natural number that is greater than 1 and cannot be formed by multiplying two smaller natural numbers. For example, 5 is prime because the only ways of writing it as a product - 1 × 5 or 5 × 1 - involves 5 itself. A natural number greater than 1 that is not prime is...
