zhenek [66]

52  

Explanation:

We need to understand and apply the rules of significant figures when carrying out addition operations to solve this problem:

Rules of significant figures:

  • Non-zero digits are always significant in a given number
  • Any zeros between two significant digits are significant.
  • A final zero or trailing zeros in the decimal portion is significant.
  • Any leading zero in a decimal is significant.

In addition, the answer of the sum is given to the least number of significant digits of the given numbers:

 

        44.2124

    +    0.81

    +    7.335

sum  52.3574          

Now the least number of significant figure is 2 as seen in 0.81

we round the sum up to 52
