Follow the PEMDAS order of operations

Calculate exponents

(2)^{2} : 4

(2)^{2}

(2)^{2} = 4

= 4

= 3 \cdot 4 - 5 (2) - 2

Multiply and divide (left to right)

3 \cdot 4 : 12

3 \cdot 4

3 \cdot 4 = 12

= 12

= 12 - 5 (2) - 2

Multiply and divide (left to right)

5 (2) : 10

5 (2)

Apply rule:

(a) = a

(2) = 2

= 5 \cdot 2

Multiply the numbers:

5 \cdot 2 = 10

= 10

= 12 - 10 - 2

Add and subtract (left to right)

12 - 10 - 2 : 0

12 - 10 - 2

12 - 10 = 2

= 2 - 2

2 - 2 = 0

= 0

= 0

(+ 5) - (- 3) - (- 1)

20 \times (4 + 18) - (12 \times 2)

14 (31 - (3 + 2)^{2})

9 7^{2} - 6 5^{2}

\frac{( 18 - 15 ) ^{2}}{15}
