Answer:168Explanation:Before we begin, remember the following:+ve * +ve = +ve -ve * -ve = +ve+ve * -ve = -ve -ve * +ve = +veNow, for the given problem we have:(-4) * (6) * (-7)Let's take the first two terms:(-4) * (6)Based on the above rules, the product will be negativeTherefore, (-4) * (6) = -24Now, the expression became:(-24) * (-7)Again, based on the above rule, the product here will be positiveTherefore,(-24) * (-7) = 168Hope this helps :)
