Solution

Each option: 1 Mark

(a). Largest = $175$ , Smallest = $- 365$

(b). $[(- 3) + (- 2)] + [(- 5) + 7]$
$\Rightarrow [- 3 - 2] + [- 5 + 7]$
$\Rightarrow [- 5 + 2] = - 3$

(c). $- 6 \div - 3 = \frac{- 6}{- 3} = 2$
( $\Rightarrow - \div - = +$ )

(d). $3 \times 6 \times 2 \times (- 40)$
$\Rightarrow 18 \times 2 \times (- 40)$
$\Rightarrow 36 \times (- 40) = - 1440$
( $\Rightarrow a s + \times - = -$ )
