$$- \frac{ 2 \pi }{ 3 } +2 \pi =$$

Evaluate

$$\frac{4\pi }{3}\approx 4.188790205$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply 2\pi times \frac{3}{3}.

$$-\frac{2\pi }{3}+\frac{3\times 2\pi }{3}$$

Since -\frac{2\pi }{3} and \frac{3\times 2\pi }{3} have the same denominator, add them by adding their numerators.

$$\frac{-2\pi +3\times 2\pi }{3}$$

Do the multiplications in -2\pi +3\times 2\pi .

$$\frac{-2\pi +6\pi }{3}$$

Combine like terms in -2\pi +6\pi .

$$\frac{4\pi }{3}$$
