How to clone a cell in excel (Google DOCS)?

Question

Google

Hello!
Tell me, is there a way to copy a cell in Google docs in excel?
Those. I need that when you enter a value (in my case, a number) in one cell, it appears in another cell. Those. they should be kind of connected - the value from one cell should be copied to another.

If I understood the question correctly, then the answer to it is as follows:
Let's say there is a 3x3 table
Value in A1 = 45
and you need B1 to have a value from A1
That means in B1 we write the formula: \u003d A1
