80

Solution steps

4 + 2 + 9 + 2 + 25 + 10 + 12 + 2 + 15 - 1

Follow the PEMDAS order of operations

Add and subtract (left to right)

4 + 2 = 6

= 6 + 9 + 2 + 25 + 10 + 12 + 2 + 15 - 1

6 + 9 = 15

= 15 + 2 + 25 + 10 + 12 + 2 + 15 - 1

15 + 2 = 17

= 17 + 25 + 10 + 12 + 2 + 15 - 1

17 + 25 = 42

= 42 + 10 + 12 + 2 + 15 - 1

42 + 10 = 52

= 52 + 12 + 2 + 15 - 1

52 + 12 = 64

= 64 + 2 + 15 - 1

64 + 2 = 66

= 66 + 15 - 1

66 + 15 = 81

= 81 - 1

81 - 1 = 80

= 80

10 - 2 (- 3) + 5 (0) - (- 7) (- 4)

(40 \times 2) - (6 \times 11)

- 3 - 1 + (- 1 - 2) - (- 2 - (- 3) + 1) - (- 2)

\frac{4 - 4}{4 ^{2} - 16}

750 \div 100 \times 600
