Question

Sir or mam
{-} × {-} = + kaise Ho ga​

Answer 1

Question:-

Proof :

- × - = +

Solution:-

let a friend to signify a positive and let a enemy signify a negative quantity. let call a good happening as positive and a bad happening as negative.

so when something good happens to your friend its positive × positive = positive. This matches how we feel happy when something good happens to our friend.

when something good happens to your enemy? its negative × positive = negative. In real life also we don't like it, its negative.

when something bad happens to your friend? we again don't like it, in real life. so in maths positive × negative = negative

and finally when something bad happens to your enemy you take it as something good. so in maths its negative × negative = positive

•°•Negative × Negative = Positive

» - × - = +
