2 + 3 - (- 4 - 4) + 5 - 7 + 4 + 72 - 23

64

Solution steps

2 + 3 - (- 4 - 4) + 5 - 7 + 4 + 72 - 23

Follow the PEMDAS order of operations

Calculate within parentheses

(- 4 - 4) : - 8

- 4 - 4

- 4 - 4 = - 8

= - 8

= 2 + 3 - (- 8) + 5 - 7 + 4 + 72 - 23

Add and subtract (left to right)

2 + 3 - (- 8) + 5 - 7 + 4 + 72 - 23 : 64

2 + 3 - (- 8) + 5 - 7 + 4 + 72 - 23

2 + 3 = 5

= 5 - (- 8) + 5 - 7 + 4 + 72 - 23

Apply rule

- (- a) = + a

- (- 8) = + 8

= 5 + 8 + 5 - 7 + 4 + 72 - 23

5 + 8 = 13

= 13 + 5 - 7 + 4 + 72 - 23

13 + 5 = 18

= 18 - 7 + 4 + 72 - 23

18 - 7 = 11

= 11 + 4 + 72 - 23

11 + 4 = 15

= 15 + 72 - 23

15 + 72 = 87

= 87 - 23

87 - 23 = 64

= 64

= 64

2^{5} \cdot 13

(- 4 - 4) + 5

- (5 - 3) - (3 - 5) - [14 - (29 - 15)]

\frac{3}{2} \cdot 3^{2}

(- 2)^{3} - 2 (- 2) + 1
