this is how my teacher explained this concept to us in the first year of high school;
if you face forward, that'll represent a positive number. if you face backwards, that'll represent a negative number.
Now if you we walk forward that'll represent multiplying it by a positive number. and if we walk backwards that'll represent multiplying by a negative number.
Well, which direction do you go if you face backwards and walk backwards?, that's right, the same direction as multiplying a positive number by a positive number.

It's probably a trolling but I would like to explain why -5 x -5 is positive, not negative. So, you are somewhere at minus scale - going left from 0. Someone says "keep going few times more". You'll be going to the left side and you'll end at let's say -25 (5 times). It's cool and easy. But now think "do the same but opposite". So you will start going to the right side. That's why minus times minus means positive. You're repeating but in opposite way.

I'm still waiting. It seems like Veeky Forums has been cucked again.

>first, think about what something being negative means. it means that it's in a different direction, in the case of traditional negative numbers, the exact opposite direction as the traditional number line. what you are imagining is

not
[math]-x*-x)[/math]

Then what should be (-x)*(-x)?

Just want to say that's an awesome pic OP

7 + (-42) = -35 spaces in total Wow, how are you fitting 42 empty spaces and 7 filled spaces into 35 'empty' spaces? What kind of witchcraft is this?

So like a robot pinball machine is playing a pinball machine, isn't this basically pinball machine foreplay?

>a negative number times a negative number should be a negative number no. a - a = 0 -> -a - (-a) = 0 -> a = -(-a)
