I'm not certain if you have specified everything you are trying to do.

But for a simple list why don't you use Part instead of Take.

list = {1, 2, 3, 4, 5};

Part[list, 2]
2

Or you could always use

First@{45}
45

Hi,
I generated a list of numbers, a sequence with the function NESTLIST.
Now I want to take singular value to operate with it. For example I
need the first value in the list, then the second, then the third...
The problem is that when I use TAKE, Mathematica gives me the value I
want, but into the brackets. Let's say, {45}. I need it to do calculus
and to put it in some formulas... How can I eliminate the brackets?
Please, help me!!!!
