Calculation of Distance
To calculate the distance between two points, the first step is to perform the operations inside the parentheses. For example, subtracting 5 from 2 results in 3. This value is then squared and placed inside the parentheses. Similarly, subtracting 13 gives -4, which is also squared. The next step involves squaring the values obtained, such as squaring 3 to get 9 and squaring -4 to get 16.
