General Negative numbers

[1031]

Okay, to preface this, math is harder for me than for some of you and yes I understand that (-4)(-12) = 48 but how is this ever practically applicable?

Like, wtf, if I lose 4 tires then I have -4 tires but then I multiply that by the negative times I have lost 4 tires in a year and now I magically have 48 fucking tires for the year?

Obviously, I am not talented when it comes to practical math (or really at all) but still, can someone make some sense of how multiplying two negatives gives me a positive and how any of this translates to real life?

Ok, so you OWE 4 tires, the multiplier is what YOU'RE owed from the bank, then divide that by the sqare root of the equilateral, and make a sandwich.

i could be mistaken. but it might help in terms of vector (when we are talking about not only value but direction. like programming behind a GPS or something)

EDIT: bad example since you used two negatives. i dunno. id bet there's a reason though in terms of geomtry or calculus. but its been too long to recall lol

Okay, *I think* I follow so far...
So you're saying, if we need to program something, then we need binary code, to represent the math end of things and direction off a given (forgive the incorrect terminology) standard starting point is best represented in + or - numbers?

or fuck maybe I have no clue what you mean :/

I bought a sandwich....I don't know what the purpose of square roots are.

I was being funny, (believe me).
But it's like this.

You are subtracting a negative.
I used "the bank" as a lender that owes you, which is how you come out ahead.

-4 × -12 =48

-(-12)-(-12)-(-12)-(-12)= +48

I have absolutely no understanding of the logic you are communicating to me.

 

[sparkuri]

It's like saying "I don't not owe you x", which is essentially owing you x.

Yeah. That's what I was getting at. Negatives hold value

But your original post was about a double negative...and u got me there. I dunno lol

Great....but that just seems impractical. Perhaps in other languages they use double negatives to communicate a positive but in English we tend, greatly, to use positives...nonetheless, now I get what you're saying (to an extent)....I still don't understand the bank aspect of it though.

actually, i have an example.

distance moved = A * B

A is always 1 or -1. 1 stands for facing east. -1 for facing west

B equals the vector of movement. postive being forward. negative being backwards.

1: 1 * 8 equals a car facing east, moving 8 units forwards (east)
2: -1 * 8 equals a car facing west, moving 8 units forwards (west)
3: 1 * -8 equals a car facing east, moving 8 units backwards (west)
4: -1 * -8 equal equals a car facing west moving 8 units backwards (east)

Let's talk about values using -4 x -12.

We are talking about cancellation of debt.

Debt vs. what's owed to you.

You lose 4 tires, vs. NOT losing 4 tires 12 times.

Sadly, I need a visual over here, I l am unable to picture this.

What debt?
Fuck that, those cunts got enough money from investing my hard-earned money already, and they charge me a service fee every month, now I start off the month owing them for shit I could hypothetically break/lose/need?

If you just walk everywhere you're good, & when it comes to math's practical applications, you won't have to worry about drawing a blank @blank .
Unless you take 4 steps backward, then don't take 4 steps backwards 11 more times.
Then you're fucked, like kwingjitsu at a conference on...literally anything.

Holy shit. This makes sense. lol. Nice.
Another way to put it would be using an x or y axis graph to show net 'movement' of integers in opposing directions (starting from zero).

after drawing it out, yes, that "works" in terms of logic but I'm missing the practical aspect of it, i.e. how is this applicable to anything practical?

it might be used in the programming code of something like a GPS. im just pulling this out of my tush. i have no idea. but in theory, im starting to think there are uses of the double negative, especially in programming

and also in financial calculation, like sparkuri was mentioning above

That is EXACTLY how I feel.

I’ve already thrown up twice because of this thread.

Has anyone had any use for algaebra since leaving school?
I was terrible at maths in school and I still am. I can't remember long multiplication or division even.
