consider the new verb monad +/, which creates the total of the items
of its operand (just think of it as 'monad SumItems'):
   +/ 1 2 3
6
The result was 1 + 2 + 3, as expected.

To be honest, it would be nice if this result were fleshed out because
all the prior examples in this section were based on operands of
rank-2.

I would describe +/ used with only a left argument as a verb which has
the same result as that of an expression where the verb + is inserted
between each of the items of the argument array of the +/ verb.

In other words:
  +/1 2 3
gives the same result as
  1+2+3

Also,
  +/i.3 2
gives the same result as
  0 1+2 3+4 5

Does this help?
