Solution: How many significant figures are there in the answer for the following problem?A) one B) two C) three D) four

Problem

How many significant figures are there in the answer for the following problem?

A) one 

B) two 

C) three 

D) four

Solution

We are asked for the number of significant figures in the answer to the problem. 


The number of significant figures depends on the operation we use:

1.  addition or subtraction - the least number of decimal places will determine the final answer. 

2. multiplication or division - the least number of significant figures will determine the final answer. 

We operate the ones in the brackets first in this order : () → [] → {}
