On Line 32, you have two fields that you're trying to add: acct.Debit__c + acct.Bank_Closing_Balance__c.
Since you're doing a null check on the Debit__c field it's most likely that you have an Account with a NULL Bank_Closing_Balance__c field.
You could also perform a null check on the Bank_Closing_Balance__c.
Line 31 would look like this.
