How to get the last number from a column/row in Google Docs?

Question

Google Sheets

Dear colleagues!
I have a question that I can't seem to find an answer to in the official Google guide.
There is a column with numbers. These numbers are added every day, by adding below, in the same column.
In another tab, I am making a formula. I need the formula to take the last number from the column that is updated every day in the next tab.
How can this be done?
Thanks for the replies!

Answer 1

In the column adjacent to the "numbers" write a formula that determines the row number =ROW (). Checking if a cell is full won't hurt =IF(...).
Define the maximum number in the table with row numbers =MAX(...).
LOOKUP'om take number from a "numerical" column from a line with the maximum number.
