I am trying to brush up on my algebra. I am getting a different answer than the back of the book. The numbers are the same but the order is different.
Write without parenthesis.
(a + b + 2) (c + d -3)
ac + ad -3a + bc +bd - 3d + 2c +2d - 6
the back of the book shows
ac + bc + ad + bd -3a - 3b + 2c + 2d - 6
What is the correct order of distribution?
