Interpretation Introduction

INTERPRETATION:

The product of the given numbers should be determined.

CONCEPT INTRODUCTION:

Significant figures:

The numbers which have meaningful contribution in its measurement are considered to be significant figures.

Certain rules have to be followed for measuring significant figures:

  • Non-zero digits are considered to be significant,
  • The numbers between two non-zero digits are significant.
  • Leading zeros are not significant.
  • For a number containing decimal point, zeros right to the last non-zero digits are significant.
  • In mathematical operations like addition or subtraction , the significant figures of the result will have the same as that of the number having least number of decimal  places.
  • In multiplication or division, the result should be rounded to least number of significant digits.
