Sometimes, you want to create a wide gate that operates on all of the bits of one vector, like (a[0] & a[1] & a[2] & a[3] ... ), which gets tedious if the vector is long. The reduction operators can do AND, OR, and XOR of the bits of a vector, producing one bit of...
times to do the shift and addition/subtraction in order to perform the multiply/division. Two's complement is assumed(ie, to negate a number, invert all bits and add 1). You may tailor it as needed for your own use. --- CUT HERE --- // Unsigned/Signed multiplication based on Patter...

Surely we need to "assign" F a value, so coding "assign F = " would be a good start... Ok, so A xnor B... We don't have an xnor symbol! No worries, we can make A XOR B then invert the entire term! This leads to a final solution of "assign F = ~(A ^ B);" ...
