Unit 2: Adding and Subtracting Decimals

Topic C: Bookkeeping

One everyday use of adding and subtracting decimals is the bookkeeping that we all must do with our money.

Here are some examples:

  • Keeping track of online payments
  • Figuring out how much money to take on a trip
  • Stretching a pay cheque over two weeks
  • Organizing the household budget
  • Deciding how much you can spend on eating out

What are some other examples of bookkeeping that you do?

The bookkeeping that most of us do is straightforward:

  • Add money received or deposited to our accounts.
  • Subtract money spent or paid out.

The result of the addition or subtraction is the balance.

Methods of Payment

There are many different methods of paying for purchases. Some of the most common methods are:

  • Cash
  • Debit card
  • Credit card
  • Cheque
  • Online payment (i.e., PayPal, e-transfer)

There are benefits to each method of payment. Each person chooses to do what works best for them depending on the situation. Here is a list of some of the benefits and drawbacks of each method of payment.

Cash

Advantages:

  • It is quick and easy to pull money out of your wallet.
  • You can see how much money you have left.
  • It is impossible to overspend.
  • It is a great method to use if you do not have a bank account.

Disadvantages:

  • It is easier to loose.
  • You may need to continue to visit the bank to get money out.
  • You might run out of cash while trying to pay at the till.

Debit Card

Advantages:

  • It is quick at the till.
  • You cannot spend more than you have in your bank account.
  • It is safe.

Disadvantages:

  • There is often a service fee when using the card to pay for shopping.
  • You cannot always use it for online shopping.

Credit Card

Advantages:

  • You only have to pay the company money once a month.
  • It is quick at the till.
  • It is easy to keep track of what you have spent because the credit card company sends you a monthly statement.
  • You can use a credit card for online shopping.

Disadvantages:

  • It is really easy to overspend your budget because you do not have to pay any money up front.
  • There are often service charges once a year that are expensive.
  • You can get into debt with a credit card and it may be really hard to get out of that debt.

Cheque

Advantages:

  • It can be convenient when you want to mail someone money.
  • It is safe.
  • The cheque book helps you keep a written record of your bank balance.

Disadvantages:

  • Some stores do not accept cheques or require several pieces of identification, usually a driver’s licence and a credit card.
  • Most banks and credit unions have a small service charge for each cheque that you write.
  • If your account is overdrawn, your cheque will be N.S.F. (Not Sufficient Funds) for which you are charged extra by the store and the bank. To avoid this, keep careful, up-to-date records so you always know your balance.

Online Payment

Advantages:

  • It allows you to shop online securely.
  • You can pay directly online with money from your bank account or your credit card.
  • You can easily send money to friends or family.

Disadvantages:

  • You may not have rights that regular banks give you when you use an online payment company.
  • The company is not local, and so any problems may be hard to resolve.
  • There are fees charged to have an online payment account.

No matter what method of payment you choose to use, it is very helpful to keep track of your money. You can use a record book to mark in when you spent money and when you were paid money. This will help with budgeting and planning.

Online Banking

Many people use online banking to keep track of their finances. When online banking, you will see a record of your transactions that looks something like this:

Date Transactions Debit Credit Running Balance
2023-01-29 Electronic Funds Transfer PAYCHEQUE 175.00 1439.66

2023-03-16 Internet Banking E-TRANSFER Larissa 100.00 1599.06

The transactions are usually recorded in chronological order, by the date and time.

Here is a description of each column:

  • Date – The date of the transaction. The examples given use this method: 2023-01-29. January 29 is the 29th day of the 1st month.
  • Debit – This is money that has gone out of the account, either through a withdrawal, a bill payment, or a transfer out.
  • Credit – This is money that is deposited into the account, either through a cash deposit, a paycheque, or a transfer in.
  • Running Balance – The amount in the bank account after each transaction.

Cheque Writing

A blank cheque with all the parts labelled. The labelled parts are described below.

  1. When you have a chequing account, you sometimes have cheques printed with your name, address and phone number, usually in the top left corner.
  2. The cheques are numbered in sequence (in order) to help you keep track of your cheques.
  3. This line is for the name of the person or institution that will be receiving the money.
  4. This line is for the amount of the cheque in numbers: $22.98.
  5. This spot is for you to write, in words, the dollars to be paid. Write the cents as a fraction over 100. If you do not use the whole line, fill unused parts of the space with a straight line so that nothing can be added. $22.98 becomes twenty-two and 98⁄100 dollars.
  6. The Memo spot is a place for details. It is useful if you want to use the cheque as a receipt, too. You might list the invoice number for the bill you are paying, for example.
  7. When you open a bank account, the bank will ask you for a sample signature for their files. Sign exactly as you plan to sign your cheques.
  8. Your bank account number and codes used at the bank will be printed on your cheques.
Any cheques you do not want cashed should have VOID or SAMPLE ONLY written on them.

As soon as you write a cheque, be sure to enter the details in your cheque book.

A cheque book is a simple accounts book or ledger. A ledger is a convenient way to record expenditures (money spent) and income.

Exercise 3

Use the information below to complete the chequing account ledger. Arrange the information in chronological order. That means put the information with the earliest date first, then the next date, and so on.
