Remember:
Line up decimal points before adding or subtracting, and fill gaps with zeros.
The number of decimal places in a product equals the total in its factors.
Dividing by a decimal: multiply dividend and divisor by the same power of 10.
Dividing by a number less than 1 gives a quotient greater than the dividend.
Estimate with rounded numbers to check that the decimal point is in the right place.
