\frac{2 \cdot ( - 2 ) + 1}{2}

- 1 \frac{1}{2}

Solution steps

\frac{2 ( - 2 ) + 1}{2}

Solve

2 \cdot (- 2) + 1 : - 3

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (- 2) : - 4

2 (- 2)

Apply rule

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

2 (- 2) = - 2 \cdot 2 = - 4

= - 4

= - 4 + 1

Add and subtract (left to right)

- 4 + 1 : - 3

- 4 + 1

- 4 + 1 = - 3

= - 3

= - 3

= \frac{- 3}{2}
