(+14)+(-12)+(-18)+(+12)

(+ 14) + (- 12) + (- 18) + (+ 12)

- 4

Solution steps

(14) + (- 12) + (- 18) + (12)

Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

+ (- a) = - a

+ (- 12) = - 12

= (14) - 12 + (- 18) + (12)

(14) - 12 = 2

= 2 + (- 18) + (12)

Apply rule

+ (- a) = - a

+ (- 18) = - 18

= 2 - 18 + (12)

2 - 18 = - 16

= - 16 + (12)

- 16 + (12) = - 4

= - 4

2 \times (- 3) - (- 3^{2})

8 - (6 - [- 3 - (4 + 10) - (- 2 - 12)] + 16) - 18

[10 + 3 \times (- 4)]^{3} \div (- 2) - (- 15)

300 - 40 (6)

86 + [- 26 + (- 18 + 7) - 16] - 47
