Follow the PEMDAS order of operations

Calculate exponents

(- 1)^{1} : - 1

(- 1)^{1}

Apply exponent rule:

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

n

is odd

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

= - 1

= 3 (- 1) + 5 - 1

Multiply and divide (left to right)

3 (- 1) : - 3

3 (- 1)

Apply rule

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

3 (- 1) = - 3 \cdot 1 = - 3

= - 3

= - 3 + 5 - 1

Add and subtract (left to right)

- 3 + 5 - 1 : 1

- 3 + 5 - 1

- 3 + 5 = 2

= 2 - 1

2 - 1 = 1

= 1

= 1

- 3 - 8 + 5

1^{2} + 2^{2} + 3^{2} + 4^{2} + 5^{2} + 6^{2}

5 - (- 2)^{2}

(- 2) \cdot 3 \cdot 3

6 \div 2 (3 \times 3)
