22

Solution steps

- 40 + 45 + 25 + 40 + (- 40) - 8

Follow the PEMDAS order of operations

Add and subtract (left to right)

- 40 + 45 = 5

= 5 + 25 + 40 + (- 40) - 8

5 + 25 = 30

= 30 + 40 + (- 40) - 8

30 + 40 = 70

= 70 + (- 40) - 8

Apply rule

+ (- a) = - a

+ (- 40) = - 40

= 70 - 40 - 8

70 - 40 = 30

= 30 - 8

30 - 8 = 22

= 22

7^{2} + 3 (15 - 7)^{2}

5 - 3 \times (2 \times (4 - 1) - 3 (- (- 5)) - 8 \div 4 - 2)

7 + (- 105) + 94

20 (- 4) \div 10 - 6 \div (5 - 7)

2 + 9 (12 \div 2 \times 6)
