Solution steps

5 (7) - 3 (9)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

5 (7) : 35

5 (7)

Apply rule:

(a) = a

(7) = 7

= 5 \cdot 7

Multiply the numbers:

5 \cdot 7 = 35

= 35

= 35 - 3 (9)

Multiply and divide (left to right)

3 (9) : 27

3 (9)

Apply rule:

(a) = a

(9) = 9

= 3 \cdot 9

Multiply the numbers:

3 \cdot 9 = 27

= 27

= 35 - 27

Add and subtract (left to right)

35 - 27 : 8

35 - 27

35 - 27 = 8

= 8

= 8

4 (- 2)^{2} - 5 (- 2) - 2

20 + 4 - 20 - 35

- 8 \cdot [4 - (- 5 + 3)]

- 9 + (7 - 11)

1400 - 800 \div 100 \times 170
