Multiplying two negative numbers together: a real world example?

[SideWinder]

It is window, not 2.

 

[Cleeecooo]

What is wrong with you? Type 1+1 into a calculator. The answer is 2. How can you not know this? Window isn't even a number.

I'm chuckling pretty heartily just now.

Lol, same I actually got someone to go on youtube and find a retarded video. I bet they watched it too

My favourite part was when desires didn't even know it was window.

You can never be old 1+1=window too many times

Reminds me of this old gem:

Lottery operator Camelot has been forced to withdraw a scratchcard because players were too innumerate to understand it, according to the Manchester Evening News.

The Cool Cash game - launched on Monday - was taken out of shops yesterday after some players failed to grasp whether or not they had won. To qualify for a prize, users had to scratch away a window to reveal a temperature lower than the figure displayed on each card. As the game had a winter theme, the temperature was usually below freezing.
But the concept of comparing negative numbers proved too difficult for some. Camelot received dozens of complaints on the first day from players who could not understand how, for example, -5 is higher than -6.​

Maths was made up by an idiot who cant count, thats what.

I was thinking today. Why are there the numbers 0123456789? Why not just 01234567 or 01234.. Crazy stuff.

I know, how about 0123456789ABCDEF?

I think our brains works with base 10 maths best.

Because someone decided we should work in base ten.

 

[Snograt]

It's because we have ten fingers, right?

It's because we have ten fingers, right?

That would seem to be the logical explanation

depends entirely on which base you use.

Anything beyond 01 is just redundant but 0123456789ABCDEF is quite handy

Q: What did the photoshopper say when he used the wrong colour?

A: #FFFFFF

 

[Shayper]

This. However if we were born with 6 fingers we would likely use modulo 6 arithmetic instead.

Hexadecimal always gets me, even though I do a maths degree

It's like proving 0.9999 is = to 1.

1/3 =0.3333 so 3/3=0.9999

BUT 3/3 is 1.

see this is why i prefer fractions - using decimals cause far too many problems

 

[Scotty123]

It's a result based upon some manipulation of mathematical axioms that describe the fundamental relationships of addition, subtraction and multiplication, e.g a+b = b + a as a very basic example.

There's a few of them and you can show that a negative number x negative number results in a positive number.

Essentially because people agreed to standardise on base 10. It might be related to almost all people having 10 digits, but there were a fair few cultures that used a different base. My guess is that it came down to dominant cultures using base 10.
