Money Matters 
Money: Coins and Bills
Every country in the world has a monetary system designed to regulate and control the government issued currency  the money.
Here we see the coins currently in use in Canada. The figures on the coins are Canadian symbols. There is a maple leaf on the penny or cent; a beaver on the nickel; the Bluenose  a swift clipper ship, built in Nova Scotia, on the dime. There's a caribou on the quarter. The large coin is worth a dollar. The water bird shown on it is called a loon. So Canada refers to its dollars as loonies. There's also a $2 coin called a "toonie". So Canada is a land of loonies and toonies instead of dollars and cents.
That's not quite true. A loonie is a Canadian dollar, and though it isn't usually worth as much as a US dollar, there was a time long ago, when, for a brief moment, it was worth a few cents more.
The US Dollar has been the standard currency in world trade for many years. But, as global communication and trade increases, the Euro in Europe and the Japanese Yen in Asia are becoming more common in international affairs.
American coins, except for the loonie, have exactly the same value as Canadian coins do. There is a penny or cent, a nickel worth 5¢, a dime worth 10¢, and a quarter worth 25¢. Though there is a halfdollar or 50¢ coin, they are not seen or used as much as quarters, dimes and nickels. We use pennies to buy bubblegum or to make wishes in wells  and not much else.
Bills to Pay Bills
American paper money known as "bills", show their value in the corners of the bill.
Most have images of former presidents on one side, and pictures of American national monuments on the other. All American paper money is the same shade of green  which is why people sometimes call them "greenbacks". Many countries in the world like Canada and Australia, have colorful paper money with intricate geometric designs that make it hard to counterfeit or photocopy.
Here we see some of the paper money "denominations" (dollar values) in use today in America. The most common bills in circulation are $1, $5, $10, $20 and $50. Automatic tellers (ATMs) can only dispense $20 bills, so we have to withdraw multiples of $20. When we make a large withdrawal at the counter instead of the ATM, the human teller will usually ask what bill denominations we want. Since $500 in 20's makes a pretty thick pile of bills, we might want $100's or $50's instead.
Talking About Money
When we talk about money, we call the decimal point "AND".
So, $7.61 is spoken "Seven dollars AND sixtyone cents". A common mistake with big amounts is to add the word "AND" in the wrong place. Most people say " three hundred AND twentyseven dollars, AND sixtythree cents" when they see $327.63  but the correct way is without the big, red AND!!! It should be said "three hundred, twentyseven dollars, AND sixtythree cents". This amount $4 267.98 should be said: "four thousand, two hundred, sixtyseven dollars, AND ninetyeight cents". We say AND only at the decimal point  nowhere else!!
Example: Write this amount of money in words: $14 357.94
Solution: Fourteen thousand, three hundred fiftyseven dollars, and ninetyfour cents.
Adding, Subtracting, Multiplying and Dividing Money
Just like whole numbers and decimals, money is based on 10, so there is no difference in approach when we Add, Subtract, Multiply or Divide amounts of money. After all, money numbers are just whole numbers with decimals. We just line up the decimal places, carry tens and hundreds when we add or multiply; borrow ones, tens and hundreds when we subtract, and so on, just like we always do. A good thing about money numbers is  they always have just 2 decimal places, so we never worry about putting in zeros, to line up decimals of different lengths. An important thing to remember  our answer must always include the dollar sign and decimal point.
