Answer:

Using the rule for Multiplication of integers.

In this question first we have to multiply the integers with same sign and then from the answer that we get is multiplied with other integer of different sign,

={(-7 × -3) × 4} ....[∵(-× - = +)]

={21 × 4}

= 84

(In multiplication we have to multiply the sign of the integers also and then assign the obtained sign to the answer)
