\( (-3).(-5).(-2) \)

When multiplying multiple negative numbers, remember that the product of two negative numbers is positive. So, in your case, \((-3) \times (-5) = 15\). Then you multiply that result by the third negative number \((-2)\), resulting in \(15 \times (-2) = -30\). Thus, the final answer is \(-30\). Multiplication can be a bit tricky at first, especially with signs involved! A common mistake is forgetting that multiplying two negatives results in a positive. Practice with different combinations can help you nail this concept. And hey, math is like a puzzle—each piece has its place!
