how do you multiply money

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
