Splitting number

I have a variable

$t = “4459156205”

I’m trying to split it into 4459 and 156205

So I thought I would try

$t[0…3]
to get 4459, but I’m getting
4
4
5
9

How can I get 4459

You can use the substring method if it’s a string … like this:

“4459156205”.Substring(0,4)

You can also use -join

-join $t[0..3]

Thank you
