Solution

Verify the associative property of $2 + (- 3) + (- 4)$
According to the Associative property of addition of integers, for any three integers $a, b and c$ , $(a + b) + c = a + (b + c)$ .
$\begin{array}{rcl} [2 + (- 3)] + (- 4) & = & 2 + [(- 3) + (- 4)] \\ - 1 + (- 4) & = & 2 + (- 7) \\ - 5 & = & - 5 \\ i . e ., L H S & = & R H S \end{array}$
Therefore, this equation follows the associative property of the addition.
