* is called the asterix, and means multiplied by. this was added to the keyboard as there is no way to tell the variable x from a number multipleied by another in computer code unless they are diffrent symbols. in maths this is often accomplished by representing multiplied by with an x and the letter x with )(.
algorithm to convert a number representing radix r1 to radix r2
Above a certain number of sides, a polygon is simply called an n-gon, with the letter "n" representing the number of sides. So, in your case, a 22-gon.
