First of all you tell the program that it's a string function, with a boolean

With a boolean what?

Next you set a (variable?) called "f_sb" to the value of "x"

Nope.

(and to take that to "x.All"?)

Nope. lol

next you have to tell the program that the (character is a number?)

Nope, i'm checking for a number type. Not parsing to a number type or telling a variable to be a number with any kind of type casting.

Now you have to call a string input

This is a string[] input (string array).

you need to tell your program to echo out certain characters [with Console.WriteLine]. You lost me here with the rest of it lol.

Those certain characters are only from the values in the string array which have all characters which can be evaluated as number types.
