A more formal definition for a number less than 20 could be, "a number x, x < 20" or if you want to express the set of all numbers less than 20 "{x | x < 20}" which is read "the set of all numbers x such that x is less than 20". In interval notation, you can write (-infinity, 20) where "infinity" should be replaced by the infinity symbol.
