What do these symbols mean?

u *= 1./N;

b += bc1;

b2 += bc2;

The numerical values in the finite element object u , as a vector (if you have a vectorial finite elements, all components) are multiplied by 1/N.

The numerical values in the finite element object bc1 , as a vector (if you have a vectorial finite elements, all components) are added to the values of the vector of values stored in b.

Accessing the values of finite objects as vectors is useful since you can do operations without costly interpolation.
