Interpretation Introduction

Interpretation:

The given masuement is to be rounded off to three significant digits.

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 1st non-significant digit is less than 5 then all the non-significant digits are dropped.

Rule 2: If the 1st 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.
