Solution steps

(- 1)^{0} - (- 1^{0})

Follow the PEMDAS order of operations

Calculate within parentheses

(- 1^{0}) : - 1

- 1^{0}

- 1^{0} = - 1

= - 1

= (- 1)^{0} - (- 1)

Calculate exponents

(- 1)^{0} : 1

(- 1)^{0}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 1)^{0} = 1^{0} = 1

= 1

= 1 - (- 1)

Add and subtract (left to right)

1 - (- 1) : 2

1 - (- 1)

Apply rule

- (- a) = + a

- (- 1) = + 1

= 1 + 1

1 + 1 = 2

= 2

= 2
