(+7)+(-2)+(-9)+(+3)+(-2)

(+ 7) + (- 2) + (- 9) + (+ 3) + (- 2)

- 3

Solution steps

(7) + (- 2) + (- 9) + (3) + (- 2)

Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

+ (- a) = - a

+ (- 2) = - 2

= (7) - 2 + (- 9) + (3) + (- 2)

(7) - 2 = 5

= 5 + (- 9) + (3) + (- 2)

Apply rule

+ (- a) = - a

+ (- 9) = - 9

= 5 - 9 + (3) + (- 2)

5 - 9 = - 4

= - 4 + (3) + (- 2)

- 4 + (3) = - 1

= - 1 + (- 2)

Apply rule

+ (- a) = - a

+ (- 2) = - 2

= - 1 - 2

- 1 - 2 = - 3

= - 3

(1 3^{2} - 1 2^{2})^{2} + (6^{2} + 7^{4})^{0}

16 - 3 + 4 + 2 - 2

3 - (4 \cdot 7 - 9) + (3 - 7 + 4) 2 - 1

(21 \div 4) \times (13 \div 4) \times (15 \div 4)

4^{2} \cdot 8
