(- 5) \cdot (+ 4) \cdot (- 2) \cdot (+ 7)

280

Solution steps

(- 5) (4) (- 2) (7)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

Apply rule

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

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

= - 20 (- 2) (7)

Apply rule

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

- 20 (- 2) = 20 \cdot 2 = 40

= 40 (7)

40 \cdot (7) = 280

= 280

3 \times (12 + 7) - (18 + 12)

- 18 - 12 - 24 - 6 (- 2)

27 + 87 \div 3 \times 2^{3}

\frac{7}{3} + 4 - \frac{8}{3} + 2 \frac{1}{3}

- (3 - 3)^{2} - 7
