Question
$[12 \times (-7)] \times 5 = $_____$ \times [(-7) \times $_____$ ]$
✓
Answer
Multiplication is associative for integers, i.e. $(a \times b) \times c = a \times (b \times c)$
So, $[12 \times (-7)] \times 5 = 12 \times [(-7) \times 5]$
So, $[12 \times (-7)] \times 5 = 12 \times [(-7) \times 5]$
