Solution steps

5 (- 1^{2} - 7 + (- 3))

Follow the PEMDAS order of operations

Calculate within parentheses

(- 1^{2} - 7 + (- 3)) : - 11

- 1^{2} - 7 + (- 3)

Calculate exponents

1^{2} : 1

1^{2}

1^{2} = 1

= 1

= - 1 - 7 + (- 3)

Add and subtract (left to right)

- 1 - 7 + (- 3) : - 11

- 1 - 7 + (- 3)

- 1 - 7 = - 8

= - 8 + (- 3)
