Whether it is better to round off after each step, or round off the final answer in the calculator display is to be stated. Concept introduction: The significant numbers are taken by counting the digits from left to right and starting by the first non-zero digit. The process of eliminating the non-significant digit is known as the rounding off. This rounding off follows three rules which are stated below as: Rule 1: If the first non-significant digit is less than 5 then all the non-significant digits are dropped. Rule 2: If the first non-significant digit is equal to or greater than 5 then last significant digit is increased by 1 and dropped all the non-significant digits. Rule 3: In a multistep calculation the non-significant digits are taken in all the steps.
