[45 - (75 - 85)] - [105 - (15 - 50)] - 145

- 230

Solution steps

[45 - (75 - 85)] - [105 - (15 - 50)] - 145

Follow the PEMDAS order of operations

Calculate within parentheses

[45 - (75 - 85)] : 55

45 - (75 - 85)

Calculate within parentheses

(75 - 85) : - 10

75 - 85

75 - 85 = - 10

= - 10

= 45 - (- 10)

Add and subtract (left to right)

45 - (- 10) : 55

45 - (- 10)

Apply rule

- (- a) = + a

- (- 10) = + 10

= 45 + 10

45 + 10 = 55

= 55

= 55

= 55 - [105 - (15 - 50)] - 145

Calculate within parentheses

[105 - (15 - 50)] : 140

105 - (15 - 50)

Calculate within parentheses

(15 - 50) : - 35

15 - 50

15 - 50 = - 35

= - 35

= 105 - (- 35)

Add and subtract (left to right)

105 - (- 35) : 140

105 - (- 35)

Apply rule

- (- a) = + a

- (- 35) = + 35

= 105 + 35

105 + 35 = 140

= 140

= 140

= 55 - 140 - 145

Add and subtract (left to right)

55 - 140 - 145 : - 230

55 - 140 - 145

55 - 140 = - 85

= - 85 - 145

- 85 - 145 = - 230

= - 230

= - 230

50 + 300 \div 50 - 4 \cdot (10 - 2)

2 \cdot 2^{0}

3^{3} + 2^{4}

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

76 - 42 + (12 - 6) + (3 - 10) - 2
