Why is multiplication of 2 negative number is a positive number?

Negative numbers Felix

@musufa619 Sorry, I guess I'm a bit odd! It's been a long time since I was in school. Can you give me an example?

@1hopefulman example -2 X -2 = 4

@musufa619 - zero doesn't go well with multiplication. It makes the result zero which is again nothing but zero :-)

When you have nothing, multiply it with nothing and get something!! :)

If you remember ,can you explain why

If you know can you explain in simple words.

@musufa619 listen (-a)b+ab=(-a)b+ab (-a)b+ab=(-a)b+ab (-a)b+ab=b(a-a) (-a)b+ab=b(a-a) (-a)b+ab=b(0) (-a)b+ab=b(0) (-a)b+ab=0 (-a)b+ab=0 (-a)b=-ab (-a)b=-ab (-a)(-b)+(-ab)=(-a)(-b)+(-a)b (-a)(-b)+(-ab)=(-a)(-b)+(-a)b (-a)(-b)+(-ab)=(-a)(b-b) (-a)(-b)+(-ab)=(-a)(b-b) (-a)(-b)+(-ab)=(-a)(0) (-a)(-b)+(-ab)=(-a)(0) (-a)(-b)+(-ab)=0 (-a)(-b)+(-ab)=0 *(-a)(-b)=ab

Haha good one
