Luis received his account statement. he needs to make sure the balance in his checkbook register is correct. to reconcile his checkbook, the first thing he should do is
subtract all of the deposits that appear in the register, but are not on the statement
put a checkmark next to all the transactions in the register that appear on the statement
add all of the transactions together
add all of the deposits that appear in the register, but are not on the statement

Explanation:

This is the first thing he should do to make sure his checkbook register is correct. Summing all numbers he'll be able to compare the total with his account statement, if there's a difference between, then he'll easily deduct that his checkbook register is wrong.

the answer is true.  i do believe this is the answer because of the amount of wrecks people get into each year.  if you double this with avoiding those so said wrecks, that would make you a "skilled" driver.
