Let’s say I have a list [2, 6, 1, 9]. Is it possible to get the position of the number in the list? For example if 6 is the input, the output would be 2 because it"s the second number in the list.

You can make a parallel list and use a conditional statement. The graph Desmos | Graphing Calculator shows an example of how to get the first occurence of a 6 in a list, though it doesn’t quite know what to do if no 6 shows up.

You can make fewer expressions by nesting list N and editing position to this:

p_{osition}=min({L=6:[1…length(L)],length(L)+1})
