You multiply money the same way you multiply any decimal number. For example, if you have five quarters, six nickels, three dimes, and seven pennies how much money do you have. First convert the monetary amount into decimal equivalent. One dollar = 1.00, One quarter = .25, one dime = .10, one nickel = .05, and one penny =.01. We have five quarters becomes (5 x .25), six nickels becomes(6 x .05), three dimes becomes (3 x .10), and seven pennies becomes (7 x .01). To find the solution we solve for the amounts in the parantheses and add up all of the amounts:

For Quarters 5 x .25 = 1.25

For Nickels 6 x .05 = 0.30

For Dimes 3 x .10 = 0.30

For Pennies 7 x .01 = 0.07

Lastly, we add up the results found in the paranthesis to get our final answer:

$1.25 in Quarters

$.30 in Dimes

$ .30 in Nickels

+$.07 in Pennies

Money comes in dollars and cents. "Cents" are "hundredth parts" of a dollar. That is why one dollar has 100 cents. Usually money amounts are given in dollars, using a decimal digits to show how many hundredths or how many cents.

For example: $15.38 means 15 whole dollars and 38 cents (hundredth parts)

In order to multiply money you would apply your knowledge of multiplying decimals. Make sure you include $ sign in your answer.

For example: $2.50 X 4 = $10

IF this is a math question, the other answers covered it.

IF this were a macroeconomics question, there's something called the "money multiplier." For Keynesians this is the aggregate effect of an increase in spending, which is some multiple of that spending. This is the basis for economic policies calling for "spending our way out of the recession."

For monetarists, there is a money multiplier in the financial sector due to fractional reserve banking. Obama early in his presidency defending policies helping banks by saying each dollar injected into the banking system would have a multiplier effect on the economy. He may have used 10 times as the multiplier.

Or there's the accounting identity MV=PQ where M is the money supply V is the velocity of money, P is the price level and Q is the quantity of products. Increase M and its effect is multiplied by V on its effect in the real sector. Initially it may directly affect Q, but eventually it causes the price level to rise, with less real effect on output

All these multipliers tend to result from fiat money, a money that is not convertible into gold or any real product. Fiat money is money because the government makes it legal tender. Otherwise it would have no value.

Always remember that when you multiply a numbers with decimals, always count the number of digits that are in back of the decimal and move the decimal point to the left that many digits after you have your product. For instance 0.07 x 0.3 = 0.021. We know that the product of 7 x 3 = 21. Because there are three digits behind (to the right) of the decimal point, we must move the decimal point three places to the left of the product.

If we move the decimal one place, we get 2.1

If we move the decimal two places, we get .21

When we move it three places, we get .021
