I need help with a bank reconciliation and making the numbers add up properly in each statement

Firstly :-

What is a bank reconciliation?
This is a statement of two positions:-
1) Your books , and
2) The Bank books.
At any given point one needs to get the balances of these two positions to balance.

It they are not equal , things have to be done
to both so that they are brought to being equal.
Your books need to be brought up to date
with the new knowledge of what the bank knows.
The bank position needs updating with what your books are portraying.
When the two positions are brought to equality, this gives you a controlled position that everything has been accounted for.
