Follow the PEMDAS order of operations

Calculate exponents

(- 1)^{2} : 1

(- 1)^{2}

Apply exponent rule:

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

n

is even

(- 1)^{2} = 1^{2} = 1

= 1

= - 3 \cdot 1 + 1

Multiply and divide (left to right)

- 3 \cdot 1 : - 3

- 3 \cdot 1

- 3 \cdot 1 = - 3

= - 3

= - 3 + 1

Add and subtract (left to right)

- 3 + 1 : - 2

- 3 + 1

- 3 + 1 = - 2

= - 2

= - 2

2^{2} + 10

2 + 1 \cdot \frac{6}{5}

80 - 2 [12 - (5 + 4)]

- 1 \frac{1}{4} + \frac{3}{4} + (- 1)

8^{2} + 1
