- 17

Solution steps

19 - 11 + (- 17) + (- 19) + 11

Follow the PEMDAS order of operations

Add and subtract (left to right)

19 - 11 = 8

= 8 + (- 17) + (- 19) + 11

Apply rule

+ (- a) = - a

+ (- 17) = - 17

= 8 - 17 + (- 19) + 11

8 - 17 = - 9

= - 9 + (- 19) + 11

Apply rule

+ (- a) = - a

+ (- 19) = - 19

= - 9 - 19 + 11

- 9 - 19 = - 28

= - 28 + 11

- 28 + 11 = - 17

= - 17

- 4 - (1 - 5) - (- 4)^{2}

15 \cdot 18 + \frac{12}{3} + 9

3 - {2 - [1 + (4 + 5) - (6 + 3)] + 1}

6 \div 2 (1 + 2)

6 \div 2 (2 + 1)
