Follow the PEMDAS order of operations

Calculate exponents

4^{2} : 16

4^{2}

4^{2} = 16

= 16

= 16 - 9 (4) + 8

Multiply and divide (left to right)

9 (4) : 36

9 (4)

Apply rule:

(a) = a

(4) = 4

= 9 \cdot 4

Multiply the numbers:

9 \cdot 4 = 36

= 36

= 16 - 36 + 8

Add and subtract (left to right)

16 - 36 + 8 : - 12

16 - 36 + 8

16 - 36 = - 20

= - 20 + 8

- 20 + 8 = - 12

= - 12

= - 12

5^{3} + 5^{2}

16 - 30 \div (6 - 2 \times (3 - 1) + 3)

(4 - 2) 180

1 - 2 (0)

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