(- 2)^{3} + (- 5) \cdot (+ 4)

- 28

Solution steps

(- 2)^{3} + (- 5) (4)

Follow the PEMDAS order of operations

Calculate exponents

(- 2)^{3} : - 8

(- 2)^{3}

Apply exponent rule:

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

n

is odd

(- 2)^{3} = - 2^{3} = - 8

= - 8

= - 8 + (- 5) (4)

Multiply and divide (left to right)

(- 5) (4) : - 20

(- 5) (4)

Apply rule

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

(- 5) (4) = - 5 \cdot 4 = - 20

= - 20

= - 8 - 20

Add and subtract (left to right)

- 8 - 20 : - 28

- 8 - 20

- 8 - 20 = - 28

= - 28

= - 28

280 \cdot (- 2) \cdot (- 5)

1 \times 10 - 2 \times 3

\frac{4}{9} - 5 + \frac{12}{5} - \frac{3}{10}

4 [(- 5)^{2} + 2 \times 7 \div 5 + 8]

- 45 + 30 - 40 + 25 - 60
