Calculate exponents

(2)^{2} : 4

(2)^{2}

(2)^{2} = 4

= 4

= 15 \cdot 4 + 10 (2)

Multiply and divide (left to right)

15 \cdot 4 : 60

15 \cdot 4

15 \cdot 4 = 60

= 60

= 60 + 10 (2)

Multiply and divide (left to right)

10 (2) : 20

10 (2)

Apply rule:

(a) = a

(2) = 2

= 10 \cdot 2

Multiply the numbers:

10 \cdot 2 = 20

= 20

= 60 + 20

Add and subtract (left to right)

60 + 20 : 80

60 + 20

60 + 20 = 80

= 80

= 80

\frac{1}{2} + 15 \div 3 + (4^{2} + 3)

- 8 (- 2)^{3} + 9 (- 2)^{2} - 2 (- 2)

20 - (- 7 - 8) - 2

(- 6) - 8 - (- 5)

(- 1)^{2} + 6 (- 1) - 7
