Question

Is it possible to increase the degree of accuracy by mathematical manipulations? Support your answer with an example.

Answer 1

1. Accuracy is the degree of closeness between a measurement and its true value.
2. It is not possible to increase the degree of accuracy by mathematical manipulation.
3. For example in the addition of $23,1.3and5.2$ the answer is
4. $$\begin{gathered} 23+ \\ 1.3 \\ 5.2 \\ \_\_\_\_\_\_ \\ 29.5 \end{gathered}$$
5. The answer can never be more accurate than this value.
6. While manipulating the value as $29or30$the answer is wrong.
