8(3)\div 2-18\div 3^2(2)^2

8 (3) \div 2 - 18 \div 3^{2} (2)^{2}

4

Solution steps

8 (3) \div 2 - 18 \div 3^{2} (2)^{2}

Follow the PEMDAS order of operations

Calculate exponents

3^{2} : 9

3^{2}

3^{2} = 9

= 9

= 8 (3) \div 2 - 18 \div 9 (2)^{2}

Calculate exponents

(2)^{2} : 4

(2)^{2}

(2)^{2} = 4

= 4

= 8 (3) \div 2 - 18 \div 9 \cdot 4

Multiply and divide (left to right)

8 (3) \div 2 : 12

8 (3) \div 2

8 (3) = 24

8 (3)

Apply rule:

(a) = a

(3) = 3

= 8 \cdot 3

Multiply the numbers:

8 \cdot 3 = 24

= 24

= 24 \div 2

24 \div 2 = 12

= 12

= 12 - 18 \div 9 \cdot 4

Multiply and divide (left to right)

18 \div 9 \cdot 4 : 8

18 \div 9 \cdot 4

18 \div 9 = 2

= 2 \cdot 4

2 \cdot 4 = 8

= 8

= 12 - 8

Add and subtract (left to right)

12 - 8 : 4

12 - 8

12 - 8 = 4

= 4

= 4

8 \cdot 3^{3}

31 + (- 40) \div (+ 2)

8 + (- 2) + 3 + 5 \cdot (- 3) + (- 7)

1 + 2 \cdot \frac{2}{5}

2^{2} + 9^{2}
