(-3)+(+2)-(-1)+(-5)-(+7)

(- 3) + (+ 2) - (- 1) + (- 5) - (+ 7)

- 12

Solution steps

(- 3) + (2) - (- 1) + (- 5) - (7)

Follow the PEMDAS order of operations

Add and subtract (left to right)

(- 3) + (2) = - 1

= - 1 - (- 1) + (- 5) - (7)

Apply rule

- (- a) = + a

- (- 1) = + 1

= - 1 + 1 + (- 5) - (7)

- 1 + 1 = 0

= 0 + (- 5) - (7)

Apply rule

+ (- a) = - a

+ (- 5) = - 5

= 0 - 5 - (7)

0 - 5 = - 5

= - 5 - (7)

- 5 - (7) = - 12

= - 12

50 - [2 + 7 (- 3)]

\frac{1}{3} (6)^{2}

(2 \div \frac{3}{4}) \cdot 6

- 2 - 1 + 1

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