There are also Negative, Positive and Zero examples when we are dealing with money

Lets look at some examples - VIDEO -

Integers and Money

• Credit is represented with a positive number

• Credit is a considered a positive transaction

• If I have a credit of forty dollars, I would use a positive number to represent that: $40

Integers and Money

• A deposit is also represented with a positive number

• A deposit is considered a positive transaction

• A debit is represented with a negative number

• A debit is taking money away from a bank account and a negative transaction

• If I have a debit of forty dollars at the bank, I owe the bank forty dollars and would use $-40 to represent it

Integers and Money

• A withdrawal is represented with a negative number
