- 1

Solution steps

(4 - 8) \div 2 - (9 - 12) \div 3

Follow the PEMDAS order of operations

Calculate within parentheses

(4 - 8) : - 4

4 - 8

4 - 8 = - 4

= - 4

= - 4 \div 2 - (9 - 12) \div 3

Calculate within parentheses

(9 - 12) : - 3

9 - 12

9 - 12 = - 3

= - 3

= - 4 \div 2 - (- 3) \div 3

Multiply and divide (left to right)

- 4 \div 2 : - 2

- 4 \div 2

- 4 \div 2 = - 2

= - 2

= - 2 - (- 3) \div 3

Multiply and divide (left to right)

(- 3) \div 3 : - 1

(- 3) \div 3

Apply rule

(- a) \div b = - a \div b

(- 3) \div 3 = - 3 \div 3 = - 1

= - 1

= - 2 - (- 1)

Add and subtract (left to right)

- 2 - (- 1) : - 1

- 2 - (- 1)

Apply rule

- (- a) = + a

- (- 1) = + 1

= - 2 + 1

- 2 + 1 = - 1

= - 1

= - 1

6^{2} - 5 (6) - 4

8 \cdot 1 0^{3}

2 \cdot (- 1) - \frac{1}{5} \cdot 1 + 7 \cdot (- 1) - 3

1 - 5^{2}

3 - (\frac{1}{5} + \frac{5}{3})
