(1/2)-1

Solution

(1/2) - 1

- \frac{1}{2}

Solution steps

(1/2) - 1

Follow the PEMDAS order of operations

Calculate within parentheses

(1/2) : \frac{1}{2}

1/2

1/2 = \frac{1}{2}

= \frac{1}{2}

= \frac{1}{2} - 1

Add and subtract (left to right)

\frac{1}{2} - 1 : - \frac{1}{2}

\frac{1}{2} - 1

\frac{1}{2} - 1 = - \frac{1}{2}

\frac{1}{2} - 1

Convert element to fraction:

1 = \frac{1 \cdot 2}{2}

= - \frac{1 \cdot 2}{2} + \frac{1}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{- 1 \cdot 2 + 1}{2}

- 1 \cdot 2 + 1 = - 1

- 1 \cdot 2 + 1

Multiply the numbers:

1 \cdot 2 = 2

= - 2 + 1

Add/Subtract the numbers:

- 2 + 1 = - 1

= - 1

= \frac{- 1}{2}

Apply the fraction rule:

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

= - \frac{1}{2}

= - \frac{1}{2}

= - \frac{1}{2}

3 (- 2) - 5 (+ 3) + 4 (- 3) - 3

\frac{12}{11} \cdot 7 - 12

80 \div 4 - 2 (2 + 1)^{2}

- 3 (- 1)^{3} - 4 (- 2)^{2}

- 4 {5 + 2 [5 + (- 8)]}
