[(19 - 20) + (14 - 15)] - [(- 7 - 13) + 12]

6

Solution steps

[(19 - 20) + (14 - 15)] - [(- 7 - 13) + 12]

Follow the PEMDAS order of operations

Calculate within parentheses

[(19 - 20) + (14 - 15)] : - 2

(19 - 20) + (14 - 15)

Calculate within parentheses

(19 - 20) : - 1

19 - 20

19 - 20 = - 1

= - 1

= - 1 + (14 - 15)

Calculate within parentheses

(14 - 15) : - 1

14 - 15

14 - 15 = - 1

= - 1

= - 1 - 1

Add and subtract (left to right)

- 1 - 1 : - 2

- 1 - 1

- 1 - 1 = - 2

= - 2

= - 2

= - 2 - [(- 7 - 13) + 12]

Calculate within parentheses

[(- 7 - 13) + 12] : - 8

(- 7 - 13) + 12

Calculate within parentheses

(- 7 - 13) : - 20

- 7 - 13

- 7 - 13 = - 20

= - 20

= - 20 + 12

Add and subtract (left to right)

- 20 + 12 : - 8

- 20 + 12

- 20 + 12 = - 8

= - 8

= - 8

= - 2 - (- 8)

Add and subtract (left to right)

- 2 - (- 8) : 6

- 2 - (- 8)

Apply rule

- (- a) = + a

- (- 8) = + 8

= - 2 + 8

- 2 + 8 = 6

= 6

= 6

- 1 \cdot \frac{1}{2} + 1

(- 15) + (- 25) + 18 + 25

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

\frac{3 ( 4 - 9 ) ^{2} + [ 6 - ( - 5 + 1 ) ]}{( 3 + 2 )}

10 \cdot 1 0^{0}
