Solve 5pi/2-2pi

$$\frac { 5 \pi } { 2 } - 2 \pi$$

Evaluate

$$\frac{\pi }{2}\approx 1.570796327$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply -2\pi times \frac{2}{2}.

$$\frac{5\pi }{2}+\frac{2\left(-2\right)\pi }{2}$$

Since \frac{5\pi }{2} and \frac{2\left(-2\right)\pi }{2} have the same denominator, add them by adding their numerators.

$$\frac{5\pi +2\left(-2\right)\pi }{2}$$

Do the multiplications in 5\pi +2\left(-2\right)\pi .

$$\frac{5\pi -4\pi }{2}$$

Combine like terms in 5\pi -4\pi .

$$\frac{\pi }{2}$$
