WebRecall that a number multiplied by its inverse equals 1. From basic arithmetic we know that: The inverse of a number A is 1/A since A * 1/A = 1 (e.g. the inverse of 5 is 1/5) All real numbers other than 0 have an inverse Multiplying a number by the inverse of A is equivalent to dividing by A (e.g. 10/5 is the same as 10* 1/5) Webmatrix is used to encrypt the messages, and its inverse is used to decrypt the encoded messages.
