How to force Mathematica to output an expression such as Input {2,3,4}-> Output 234=24

Question

How to force Mathematica to output an expression such as

Input {2,3,4}-> Output 2*3*4=24

as a Times like this one:

Input Times[2,3,4] -> Output 24

do you mean you want to show the intermediate steps? Otherwise, you can try Times @@ lst where lst={2,3,4} — Nasser, Commented Mar 18, 2020 at 7:11

lst = {2, 3, 4};

Apply[Inactive[Times]]@# == Times @@ # &@lst

2*3*4==24

Or, for purposes of display,

Inactive[Set][Apply[Inactive[Times]]@#, Times @@ #] & @ lst

2*3*4=24

and

Row[{Inactive[Times] @@ #, Times @@ #}, "="] & @ lst

2*3*4=24
