Equations after the first paragraph of the section.

Regarding:

P(S1,S2) = P(S1, S2,Y=–1) + P(S1, S2,Y=+1) +
= P(S1, S2 | Y=–1)P(Y=–1) + P(S1, S2 | Y=+1)P(Y=+1) +
= P(S1|Y=–1)P(S2|Y=–1)P(Y=–1) + P(S1|Y=+1)P(S2 | Y=+1)P(Y=+1)

There are equations on three lines. Why do the first two lines of the equations end with a plus sign (+) followed by lines that begin with equals signs? What operation is represented by this? Is something missing after the plus signs? Or are the plus signs at the ends themselves typographical errors?
