Your code seems to use a class Rational ( in the 5th line, didn't you need a 'R' capitalized? ), which as two properties 'p' and 'q' where: Rational r = new Rational(p,q); // r = p/q Guessing that yur code sample go in a method of the class Rational, the code calculate the sum of the actual/current ( this ) Rational object with another ( 'r' in your example ), and return a new Rational(P,Q) where: P = this.p * r.q and Q = this.q * r.q ... because: ( a/b ) + ( c/d ) <=> ( ( a*d ) / ( b*d ) ) + ( ( c*b ) / ( b*d ) ) <=> ( a*d + c*b ) / ( b*d )
