Re: mathematical problem.... Actually I was factor it differently, like you used 3*(2*9)=3*18=54. I factor it 2*3=6*9=54 that's why it become the same answer.I am trying for different answer friend.It's by mistake matched with your answer. __________________ Brijesh Jain brijesh.tester@yahoo.co.in http://softwaretestingexpertise.blogspot.com
