This explicit verb seems to produce what you want,
u=. 3 : '(+1:)`*`%`(+2:)@.((0,(1+2&|),3:) y) y'"0

As always Brian, I am impressed; and probably will be even more so after the
time it will take me to understand the documents you and Jimmy referenced.
Long ago I concluded that

The expression X exp1;exp2;exp3 Y needs ()'s to be properly constructed as a 5

Not quite. The example in my original email was probably overly minimal to be
completely unhelpful.
This is closer to what I am trying to do:

Thank you.
I may reply more in a year ot two when I have fully grokked Roger’s note in
your reply!
Wanting to be snippy in a complaint I was making to my local bank, I wanted to
compare how many prime numbers my iPhone (using J) could calculate in the 15
seconds their cash machine took to read
Hi,
The first vocabulary is full of information. So much so that it is easy to
overlook lots of "tasty tidbits".
The answer your question " where is that first explained to the J Beginner
? " , it is not so much explained but rather demonstrated.
I had to change my reading style from "passive assi
As shown throughout the Vocabulary.
But where is that first explained to the J Beginner?

Another rabbit hole…
This expression format is used throught the original Iverson/Hui Vocabulary,
and I had always been bothered that I had to figure out what was going on
before I could get much value from the Vocabulary examples.
To investigate what I had missed long ago, I was in JHS, and
