Answer:
the verb fun takes three integers as input.
the output has three sections.
1. The first section is the product of the first two integers.
2. The second section is the product of the first and third integers.
3. the third section is the sum of those first two products, minus the
second integer.
The final output is a vector of the three results, with the spaces removed.
This should hold true for any three integers.
rb =:]#~(' '~:]) NB. Remove all blanks
'a b c' =. 2 4 6
fun =. 3 : 'rb ": (a*b), (a*c), ((a*b)+(a*c)-b)'
fun
81216
'a b c' =. 9 9 9
fun
