Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (2) : 4

2 (2)

Apply rule:

(a) = a

(2) = 2

= 2 \cdot 2

Multiply the numbers:

2 \cdot 2 = 4

= 4

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

Multiply and divide (left to right)

3 (- 2) : - 6

3 (- 2)

Apply rule

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

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

= - 6

= - (- 1) + 4 - (- 6)

Add and subtract (left to right)

- (- 1) + 4 - (- 6) : 11

- (- 1) + 4 - (- 6)

Apply rule

- (- a) = a

- (- 1) = 1

= 1 + 4 - (- 6)

1 + 4 = 5

= 5 - (- 6)

Apply rule

- (- a) = + a

- (- 6) = + 6

= 5 + 6

5 + 6 = 11

= 11

= 11

- 2 \cdot 1^{2}
