Count the number of zeros to the left of the decimal point in the multiple of ten that you are using: Examples: 10 (1 zero); 1,000,000 (6 zeroes); 100.0 (2 zeroes) Move the decimal point to the right by that number of spaces (if you run out of spaces to move the decimal point then add a zero) Examples: 5 * 1,000 = 5000 .005 * 10000 = 50 5000 * 10 = 5000
