That's not a good attitude to have.

People shouldn't be told to "deal and live with it" when they show interest in things.

13. I don't know - the whole idea makes my brain have a blue screen of death the concept of multiplying a negative amount of something by a positive amount is like trying to divide by zero to me...obviously it makes sense mathetically, I just don't know enough to approach it properly

Best, easiest and most respectful explanation so far, thanks I love using the double-negative for comic effect, so it's great you used it for comparison
(Original post by Med_medine)
Simply because multiplication means how many of the thing you have , for example

5x3 means you have 5 threes or 3 fives

Therefore -1 x -1 means you have negative one negative ones, aka a positive one
If you have a negative neg, you get a positive, the same law as having a positive positive, you get a positive.
