2/7-1/2*4/14-(1/2-3/4)

\frac{2}{7} - \frac{1}{2} \cdot \frac{4}{14} - (\frac{1}{2} - \frac{3}{4})

\frac{11}{28}

Solution steps

\frac{2}{7} - \frac{1}{2} \cdot \frac{4}{14} - (\frac{1}{2} - \frac{3}{4})

\frac{4}{14} = \frac{2}{7}

= \frac{2}{7} - \frac{1}{2} \cdot \frac{2}{7} - (\frac{1}{2} - \frac{3}{4})

Follow the PEMDAS order of operations

Calculate within parentheses

(\frac{1}{2} - \frac{3}{4}) : - \frac{1}{4}

= \frac{2}{7} - \frac{1}{2} \cdot \frac{2}{7} - (- \frac{1}{4})

Multiply and divide (left to right)

\frac{1}{2} \cdot \frac{2}{7} : \frac{1}{7}

= \frac{2}{7} - \frac{1}{7} - (- \frac{1}{4})

Add and subtract (left to right)

\frac{2}{7} - \frac{1}{7} - (- \frac{1}{4}) : \frac{11}{28}

= \frac{11}{28}

3 x (x + 1) - \frac{( x - 2 ) ^{2}}{2} = (x + 1) (x - 1) + 15

2 x \cdot 2 x

lo g_{16} (4) = 2

18 x + 30 y

9 x^{2} = 6 x - 1
