3 (1) (2)^{2}

Follow the PEMDAS order of operations

Calculate exponents

(2)^{2} : 4

(2)^{2}

(2)^{2} = 4

= 4

= 3 (1) \cdot 4

Multiply and divide (left to right)

3 (1) \cdot 4 : 12

3 (1) \cdot 4

3 (1) = 3

3 (1)

Apply rule:

(a) = a

(1) = 1

= 3 \cdot 1

Multiply the numbers:

3 \cdot 1 = 3

= 3

= 3 \cdot 4

3 \cdot 4 = 12

= 12

= 12

3 \cdot 2 - 2

3 {20 - [6^{2} - 3 (10 - 4)]}

8 - 6 \div (4 - 2)

(\frac{12}{3})^{3} \div 2^{5}

9 \times 5 + 2
