Finding the CDF

Let U, V be random numbers chosen independently from the interval [0,1] with uniform distribution. Find the cumulative distribution and density of each of the variables (a) Y = U + V .

Attempt; I first tried to think of a reasonable CDF which was F(x)=2y-y^2, and I thought a good interval it should be on is [0,1], that way I can get the interval [0,1] from the CDF. However, the answer in the book said the CDF was (a) F(y)=(y^2/2, [1,2]; 1-(2-y)^2/2, [1,2],) How are they getting this CDF?
