\pi -2\left(\frac{\pi }{2}-\frac{2h}{2}\right)
To add or subtract expressions, expand them to make their denominators the same. Multiply h times \frac{2}{2}.
\pi -2\times \frac{\pi -2h}{2}
Since \frac{\pi }{2} and \frac{2h}{2} have the same denominator, subtract them by subtracting their numerators.
\pi -\left(\pi -2h\right)
Cancel out 2 and 2.
\pi -\pi -\left(-2h\right)
To find the opposite of \pi -2h, find the opposite of each term.
\pi -\pi +2h
The opposite of -2h is 2h.
2h
Combine \pi and -\pi to get 0.
