Question

Arrange the following in ascending order.

i. $21\times (-34)\times (-12)$

ii. $(7\times 8)-9$

iii. $21\times (-34)\times \left(12\right)$

Answer 1

Here,

$21\times (-34)\times (-12)=8568$$\left[0.5mark\right]$
$(7\times 8)-9=47$$\left[0.5mark\right]$
$21\times (-34)\times \left(12\right)=-8568$$\left[0.5mark\right]$

$\therefore -8568<47<8568$$\left[0.5mark\right]$
