13-(4)+5-{2-[4-(-7)+10]}

13 - (4) + 5 - {2 - [4 - (- 7) + 10]}

33

Solution steps

13 - (4) + 5 - {2 - [4 - (- 7) + 10]}

Follow the PEMDAS order of operations

Calculate within parentheses

{2 - [4 - (- 7) + 10]} : - 19

2 - [4 - (- 7) + 10]

Calculate within parentheses

[4 - (- 7) + 10] : 21

4 - (- 7) + 10

Add and subtract (left to right)

Apply rule

- (- a) = + a

- (- 7) = + 7

= 4 + 7 + 10

4 + 7 = 11

= 11 + 10

11 + 10 = 21

= 21

= 2 - 21

Add and subtract (left to right)

2 - 21 : - 19

2 - 21

2 - 21 = - 19

= - 19

= - 19

= 13 - (4) + 5 - (- 19)

Add and subtract (left to right)

13 - (4) + 5 - (- 19) : 33

13 - (4) + 5 - (- 19)

13 - (4) = 9

= 9 + 5 - (- 19)

9 + 5 = 14

= 14 - (- 19)

Apply rule

- (- a) = + a

- (- 19) = + 19

= 14 + 19

14 + 19 = 33

= 33

= 33

15 (20)^{2} + 15 (20) + 30

14 - 8 + (2^{3} \div 2)

6 + 8^{2} \div 2

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

- 36 \div 2^{2} + 5
