For positive powers:
The rule is to move the digits in the place value columns left (for multiplication) or right (for division) the same number of columns as the power of 10.
However, on paper this is not easy to do so the effect on the decimal point relative to the digits is used instead: move the decimal point the same number of digits right (for multiplication) or left (for division); if there are less digits than required to be moved, insert zeros until the decimal point has moved the required number of digits.
If the power is negative reverse the direction of movement (eg with moving the decimal point, to multiply move the decimal point left and divide by moving the decimal point to the right).

Can you use the rule for multiplying by the reciprocal to divide whole numbers such as 10 divided by 2 explain?
Yes, you can use the rule for multiplying by the reciprocal to divide whole numbers. To divide 10 by 2, you can rewrite the division as multiplying by the reciprocal of 2. This means you would calculate (10 \times \frac{1}{2}), which equals 5. Thus, dividing by 2 is the same as multiplying by its reciprocal.

What is a rule that works for multiplying powers of the same base in exponents?
To multiply powers with the same base, you add the exponents. For example, 10^2 x 10^3 = 10^5. Similarly, to divide powers with the same base, you subtract the exponents. For example, 10^3 / 10^5 = 10^(-2).
Why does multiplying numbers by 10 move the decimal to the right but multiplying numbers By .10 you move the decimal to the left?
