Solution steps

- 1 + 2 + 4 - 5 + 7 + 6 - 8 - 9 + 12

Follow the PEMDAS order of operations

Add and subtract (left to right)

- 1 + 2 = 1

= 1 + 4 - 5 + 7 + 6 - 8 - 9 + 12

1 + 4 = 5

= 5 - 5 + 7 + 6 - 8 - 9 + 12

5 - 5 = 0

= 0 + 7 + 6 - 8 - 9 + 12

0 + 7 = 7

= 7 + 6 - 8 - 9 + 12

7 + 6 = 13

= 13 - 8 - 9 + 12

13 - 8 = 5

= 5 - 9 + 12

5 - 9 = - 4

= - 4 + 12

- 4 + 12 = 8

= 8

2 + (10 + 6) \div 8 - (1 + 3)

\frac{4 - 6 ( 3 )}{5}

(2 + 3)^{2} - (3 - 5)^{3}

((- 10 + 6) - (- 4 - 2)) + (6 - (3 - 1))

(9 + 2 \times 5 + 1) \div 4 + 4 \times (6 - 8 \div 2)
