When preparing a trial balance, Jon notices that the totals for the two columns don't match. Specifically, the total in the debit column

is $$40$ less than the total in the credit column. Jon rechecks his math and confirms that it's correct. Jon's next step should be to

scan the trial balance to see whether a $$20$ balance has been entered into the wrong column.

check the debit column for a transposition error by comparing all debit entries against the corresponding ledger entries.

check the credit column for a transposition error by comparing all credit entries against the corresponding ledger entries.

scan the trial balance to see whether a $$40$ balance has been entered into the wrong column.
