Fold Scan Map Head/tail Index (with an array) The integers up to n Concatenate Flatten Most of the operators are already familiar but they tend to work well on multidimensional arrays and with each other due to broadcast semantics (and some axis selection features). In other languages you may see the magic broadcasting for some operations like addition but many of the functions only work on vectors.
