Evaluate -(3pi)/4+pi

$- \frac{3 π}{4} + π$

Step 1

To write $π$ as a fraction with a common denominator, multiply by $\frac{4}{4}$ .

$- \frac{3 π}{4} + π \cdot \frac{4}{4}$

Step 2

Combine fractions.

$- \frac{3 π}{4} + \frac{π \cdot 4}{4}$

Combine the numerators over the common denominator.

$\frac{- 3 π + π \cdot 4}{4}$

Step 3

Simplify the numerator.

Move $4$ to the left of $π$ .

$\frac{- 3 π + 4 \cdot π}{4}$

Add $- 3 π$ and $4 π$ .

$\frac{π}{4}$

Step 4
