Insert, an adverb, consumes the entire verb its left. The entire verb left of / is =&0@:+ Hence parenthesize the verbs.
coprime =. =&0@:(+/)@:(e.&q:) 5 coprime 6 1

I do not understand why this verb fails. coprime =. =&0@:+/@:(e.&q:) 5 coprime 6 returns 0. My understanding is thus: Verb is read right to left.First : 5 (e.&q:) 6 is evaluated. This equates to (q: 5) e. (q: 6). (which gives 0) Next +/ acts monadically on this result. Finally we compare the result with 0. So my understanding is 5 coprime 6 should return 1. Regards.
