10

Solution steps

3 (- 2)^{2} - 2

Follow the PEMDAS order of operations

Calculate exponents

(- 2)^{2} : 4

(- 2)^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

n

is even

(- 2)^{2} = 2^{2} = 4

= 4

= 3 \cdot 4 - 2

Multiply and divide (left to right)

3 \cdot 4 : 12

3 \cdot 4

3 \cdot 4 = 12

= 12

= 12 - 2

Add and subtract (left to right)

12 - 2 : 10

12 - 2

12 - 2 = 10

= 10

= 10

\frac{9}{14} - 4 \times \frac{1}{2} \div 7

(19 - 4) + 14

3 (- 2)^{2} + 1

4 (- 7) + 1

3 \times (5 + 2)
