\frac{π}{4} - 2 π

Decimal Notation

Solution steps

\frac{π}{4} - 2 π

Convert element to fraction:

2 π = \frac{2 π 4}{4}

= \frac{π}{4} - \frac{2 π 4}{4}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{π - 2 π 4}{4}

π - 2 π 4 = - 7 π

= \frac{- 7 π}{4}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{7 π}{4}

n + 6 = - 14

7 a + 2 = 4 a - 10

- 2 (x + 7) + 38 \leq 4 (2 - x)

5 x - 2 + x = 9 + 3 x + 10

- 2 + 3 (- 1) \geq \frac{1}{4}
