You multiply or divide by powers of ten for small changes in the order of magnitude, or powers of 1000 for larger changes.

It is not. For positive powers of ten, the decimal point moves to the right when multiplying and to the left when dividing. For negative powers of ten the point moves in the opposite directions.

It is not. For positive powers of ten, the decimal point moves to the right when multiplying and to the left when dividing. For negative powers of ten the point moves in the opposite directions.

You move the decimal place by as many positions as the number in the exponent.Examples (using "^" for powers): * To multiply by 10^5, you move the decimal point 5 positions to the right. * To multiply by 10^(-6), you move the decimal point 6 positions to the left. * To divide by 10^6 is the same as to multiply by the reciprocal - by 10^(-6). See the previous example.
