Is 18 an irrational number?

NO!! Irrational Numbers are those where the decimal digits go to infinity AND there is no regular order in the decimal digits. pi = 3.141592.... is the most well known irrational number. as are the 'Square roots' od prime numbers;-# sqrt(2) = 1.414213.... sqrt(3) = 1.73205... sqrt(5) = 2.23606... However, such as numbers as 3.3333..... is NOT irrational, because the decimals are in regular order. Similarly 2.373737.... or 5 .678678678.... Are NOT irrational because the decimals are in a regular order. NB '....''' at the end of a decimal is the mathematical indication of recurring to infinity.
