http://thenewboston.org/list.p... I have little hard time because we did differently. I watched this video and helped me to understant an  American way to do the math what ever the way , the answers are always the same. Some of thier process make good sence  ( I thought  we should have learned that way ) some of them are complicated ( not simple) I could not agree with thier answer. y( 2-a ) ----------  = y was their answer. I could not agree with it  and my answer is -y . a- 2 (y)(-a +2)               (y) (-1)(a-2) -------------  ,       ---------------------       cross out a-2  and the remaining is y*-1 = -y  am I right or worng ? a-2                               a-2 Thank you.
