2

= 2 - 2^{2} + (- 3) \cdot 2 - 1

Follow the PEMDAS order of operations

Calculate exponents

2^{2} : 4

2^{2}

2^{2} = 4

= 4

= 2 - 4 + (- 3) \cdot 2 - 1

Multiply and divide (left to right)

(- 3) \cdot 2 : - 6

(- 3) \cdot 2

Apply rule

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

(- 3) \cdot 2 = - 3 \cdot 2 = - 6

= - 6

= 2 - 4 - 6 - 1

Add and subtract (left to right)

2 - 4 - 6 - 1 : - 9

2 - 4 - 6 - 1

2 - 4 = - 2

= - 2 - 6 - 1

- 2 - 6 = - 8

= - 8 - 1

- 8 - 1 = - 9

= - 9

= - 9
