(-7)+(-9)-(+6)-(-13)-(-21)

(- 7) + (- 9) - (+ 6) - (- 13) - (- 21)

12

Solution steps

(- 7) + (- 9) - (6) - (- 13) - (- 21)

Follow the PEMDAS order of operations

Add and subtract (left to right)

Apply rule

+ (- a) = - a

+ (- 9) = - 9

= (- 7) - 9 - (6) - (- 13) - (- 21)

(- 7) - 9 = - 16

= - 16 - (6) - (- 13) - (- 21)

- 16 - (6) = - 22

= - 22 - (- 13) - (- 21)

Apply rule

- (- a) = + a

- (- 13) = + 13

= - 22 + 13 - (- 21)

- 22 + 13 = - 9

= - 9 - (- 21)

Apply rule

- (- a) = + a

- (- 21) = + 21

= - 9 + 21

- 9 + 21 = 12

= 12

9 + 5 - 4 + 3 - 8 + 5 \times 3 - 20 \div 4 \times 3

\frac{8 + 4 \cdot 7}{( 9 - 6 ) ^{2}}

\frac{1}{2} + 2 - \frac{3}{4}

- \frac{4}{3} + 6 - \frac{1}{2}

\frac{32}{3} - 16 + \frac{32}{5}
