(+8)+(+9)+(-9)+(-7)+(-4)

(+ 8) + (+ 9) + (- 9) + (- 7) + (- 4)

- 3

Solution steps

(8) + (9) + (- 9) + (- 7) + (- 4)

Follow the PEMDAS order of operations

Add and subtract (left to right)

(8) + (9) = 17

= 17 + (- 9) + (- 7) + (- 4)

Apply rule

+ (- a) = - a

+ (- 9) = - 9

= 17 - 9 + (- 7) + (- 4)

17 - 9 = 8

= 8 + (- 7) + (- 4)

Apply rule

+ (- a) = - a

+ (- 7) = - 7

= 8 - 7 + (- 4)

8 - 7 = 1

= 1 + (- 4)

Apply rule

+ (- a) = - a

+ (- 4) = - 4

= 1 - 4

1 - 4 = - 3

= - 3

(- 10) + (- 29) + (- 37)

4^{3} \times 3^{2} + [23 - (18 - 15)]

- 1 \cdot \frac{1}{2} - 0 \cdot \frac{53}{2}

((- 3) - (- 5))^{3} \times (- 2) - (- 3)

4 \times 1^{2} - 7 \times 1 + 5
