Why does a negative time a negative equal a positive?
Answer: As multiplying with negative will change the sign, a negative times a negative equal a positive
.We know that negative times anything means that it will change the sign.
Now, let's have a negative number. We multiply it with another negative number.
Ideally, the second negative should change the sign of our original number (which is also negative).
So, our original negative sign is changed into a positive sign when a negative is multiplied to it.
