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

= 12 (- 1) - 3 \cdot 1

Multiply and divide (left to right)

12 (- 1) : - 12

12 (- 1)

Apply rule

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

12 (- 1) = - 12 \cdot 1 = - 12

= - 12

= - 12 - 3 \cdot 1

Multiply and divide (left to right)

3 \cdot 1 : 3

3 \cdot 1

3 \cdot 1 = 3

= 3

= - 12 - 3

Add and subtract (left to right)

- 12 - 3 : - 15

- 12 - 3

- 12 - 3 = - 15

= - 15

= - 15

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

4 (- 5) + 3

13 - 2 \times 5 + 7^{2}

2 - 3 + 6

5 (7) - 3 (8) + 11
