Interpretation Introduction

Interpretation:

The number 93.246 has to be rounded off to three significant figures.

Concept Introduction:

Rules for rounding off numbers:

Rule 1:  When the first digit after those that are wanted to retain is 4 or less, that digit and all others to its right are dropped.  The last digit retained is not changed.

Rule 2:  When the first digit after those that are wanted to retain is 5 or more, that digit and all others to its right are dropped.  The last digit retained is increased by one.
