+\item Corresponding array dimensions must either be equal or, one of them must be 1. 
+\item In case all dimensions are equal, ordinary element-by-element arithmetic takes place.
+\item When one of the dimensions is 1, the array with that singleton dimension gets copied along 
+that dimension until it matches the dimension of the other array.
