**Multiplication of negative numbers**

-4 × -4 = 16

-6 × -8 = 48

-90 × -4 = 360

-20 × -600 = 12000

-800 × -40 = 32000

-300 × -300 = 900

**Frequently Asked Questions**

**1. What are the rules when multiplying Positive and Negative intergers?**

● When the signs of the numbers are not similar,the answer is negative. This means, (-)×(+)=(-). For instance, -4×6=-24.

● Whe the signs of the numbers are similar, the answer is positive.(+)×(+)=(+) ; (-) ×(-).

**2. Why do you get positive answer when multiplying two negative numbers?**

For instance, when I say “go to school” , I am encouraging you to go to school(positive). On the other hand, when i say “do not go to school” it’s the opposite(negative). Therefore, if I say, “Do Not not go to school”, it means “Go to school”, that’s positive.

Others include topographical features of the earth surface, electrical circuits, and directional antenna arrays.
