-1-1((-6)/7)

- 1 - 1 (\frac{- 6}{7})

- \frac{1}{7}

Solution steps

- 1 - 1 \cdot (\frac{- 6}{7})

Apply the fraction rule

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

- \frac{6}{7}

= - 1 - 1 \cdot (- \frac{6}{7})

Follow the PEMDAS order of operations

Multiply and divide (left to right)

1 \cdot (- \frac{6}{7}) : - \frac{6}{7}

1 \cdot (- \frac{6}{7})

Apply rule

a \cdot (- b) = - a \cdot b

1 \cdot (- \frac{6}{7}) = - 1 \cdot \frac{6}{7} = - \frac{6}{7}

= - \frac{6}{7}

= - 1 - (- \frac{6}{7})

Add and subtract (left to right)

- 1 - (- \frac{6}{7}) : - \frac{1}{7}

- 1 - (- \frac{6}{7})

Apply rule

- (- a) = + a

- (- \frac{6}{7}) = + \frac{6}{7}

= - 1 + \frac{6}{7}

- 1 + \frac{6}{7} = - \frac{1}{7}

= - \frac{1}{7}

= - \frac{1}{7}

2^{6} + 2^{5} + 2^{4}

53 + (- 104) + 34 - (- 56)

- 5 + (- 8) + 6

1 - 4 \times (3 - 6 \div 2) - 5 \times 3

- (- 8 + (4 - 7) + (2 - 5 - 3)) + ((6 - 3) - (2 - 5 - 6) - 12)
