Did you do a reduce and get confused about how it got the final answer? Do you just want to see the computer write out it’s work? Check it:

1

(1,2,3).reduce({ $^a / $^b })
RESULT«0.166666666666667»

(1,2,3).reduce({"($^a / $^b)"})
RESULT«"((1 / 2) / 3)"»


(1,2,3).reduce({ $^b / $^a })
RESULT«1.5»

(1,2,3).reduce({"($^b / $^a)"})
RESULT«"((3 / 2) / 1)"»

How cool is that?
