How to extract elements of a list and append?
2
$begingroup$
A beginner's question:
Is there a way to extract elements of a list and append them into ONE number?
For example, if there is a list L={13,5,8,0}, then I am looking for a way to append 13, 5, 8 and 0 to produce the result 13580.

You can convert the list numbers to strings, then join and finally convert back to number:
L = {13, 5, 8, 0};
ToExpression[StringJoin[ToString /@ L]]

(+1) you will need something likeFromDigits[Flatten@IntegerDigits@L]to cover cases likeL={1, 13, 5, 8, 0}.
