0

Solution steps

2 (- 3)^{2} + 4 (- 3) - 6

Follow the PEMDAS order of operations

Calculate exponents

(- 3)^{2} : 9

(- 3)^{2}

Apply exponent rule:

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

n

is even

(- 3)^{2} = 3^{2} = 9

= 9

= 2 \cdot 9 + 4 (- 3) - 6

Multiply and divide (left to right)

2 \cdot 9 : 18

2 \cdot 9

2 \cdot 9 = 18

= 18

= 18 + 4 (- 3) - 6

Multiply and divide (left to right)

4 (- 3) : - 12

4 (- 3)

Apply rule

a \cdot (- b) = - a \cdot b

4 (- 3) = - 4 \cdot 3 = - 12

= - 12

= 18 - 12 - 6

Add and subtract (left to right)

18 - 12 - 6 : 0

18 - 12 - 6

18 - 12 = 6

= 6 - 6

6 - 6 = 0

= 0

= 0

(- 26) + (- 18) - 67

3^{4} + 2^{4}

7 + \frac{12}{24} - \frac{6}{8}

\frac{3}{5} \div 2 + 3 \cdot \frac{1}{4}

(6)^{2} - 5 (6) - 4
