Voltage Questions

"I am reading the book ""How to Create a CPU"" and the following circuit came out, but I don't know why the voltage at point A is 2.44V."

When I looked it up myself, I thought I would use Kirch Hop's second law, but I couldn't think of a solution.

I look forward to your kind cooperation.

I think it's an off topic, but just the way of thinking
The lower half is a composite resistance of 10 k と and 200 k の.
Therefore, the resistance value is 9.5238 K 。.
If you divide the voltage by the resistance 10K 9 and 9.5238K br above,
The voltage at point A is 5*9.5238 ((10+9.5238)=2.439V 22.44V.
