WebbSimplification of Expressions For small regular expressions, one can often see how to construct an equiva-lent automaton directly without going through the mechanical procedure of the previous lecture. It is therefore useful to try to simplify the expression first. For regular expressions α,β, if L(α)=L(β), we write α ≡ β and say that WebbTo simplify an expression with fractions find a common denominator and then combine the numerators. If the numerator and denominator of the resulting fraction are both divisible by the same number, simplify the fraction by dividing both by that number. Simplify any resulting mixed numbers.
