CHAT So, a question on negative numbers

[byronandkathy2003]

Oh my goodness..

You broke my brain

i have brain sprain

 

[mzkitty]

Shall we talk about asymptotes?

A.little know fact: five out of four people do not understand fractions.

Seventy percent of all statistics are made up. (I made that up)

I liked fractions; I even knew how do do square roots; I got through Algebra and Plane Geometry. Then I skipped straight to Einstein. Wore myself out and now I'm a math dunderhead.

 

[Silverfox]

It's all in your head

 

[Donald Shimoda]

Of course, all this leads to “imaginary numbers” (the square root of a negative number).

Howzabout hyperreal numbers?

 

[Donald Shimoda]

a negative times a negative = a positive.


WHY IS THAT TRUE?

Here's a nice look at this topic:

Why is a negative number times a negative number a positive number?

 

[Shooter]

Because Sister Martha said so. You don't argue with Sister Martha.

damn right, dont mouth off to a nun, mine had a yard stick with a brass edge. well it was more like A 1 inch by 2 inch piece of lumber, with a 1/4 inch piece of brass imbeded in it. shed almost break your knuckles. then complain because your penmanship sucked.

97% of climate scientists are idiots.

I blame electrons

 

[ComCamGuy]

And scientists state 67% of people will believe whatever is said if it is preceded by “scientists say”. But 72% of all statistics are made up, 48% on the spot.

Thanks Dennis for bringing back memories of why I hated school

If you add a negative to a negative, it goes more negative. (It’s the same as subtracting a positive from it.) You have to add a positive to a negative (same as subtracting a negative) to get it to go more positive.

And now to quote Austin Powers, “Oh my, I’ve gone crosseyed.”

no no no no no no! you made it go away now!

you have to say "yes, hunybee" or "no, hunybee".

when you say all that stuff i still don't know if i got it right or not.

stupid math

i'm like a checker eating chimp....

 

[hunybee]

Yes, because now you're going in a positive direction.

Why didn't I think of that?

really?!! i did it? no joke?

Ya'll and your letters.
Had to look it up.
I'm a dang INTJ. Drives DH out of his mind,

 

[Dobbin]

A negative times a negative is a positive because it indicates that there is a lack of the lack of something. Or in other words, if you don't have an insufficiency of something you do have a sufficiency of it, which would be a positive.

How's that for an explanation from someone who never studied higher math?!!!!! (:

Actually, that makes a lot of sense!

It has to do with the operation of additive inverses.

Start with a positive 3.

Take the opposite of 3, the result is -3 (or the inverse of 3).

Now, take the opposite (inverse) of -3...written as -(-3)

...and voila,the result is a positive 3...right back where we started.

OMG . . . an actual, real life, female INTJ . . .

OMG . . . an actual, real life, female INTJ . . .

NO WAY!!!!!​

that would inconsistent with universal laws - potentialy damaging to the time space continuum - unless of course she was a female VULCAN

[The Mountain]

I prefer to think of the "negative" as an additional operator rather than a part of the number. So when you multiply two negative numbers, the negative of the second number also gets applied as an operation, and cancels the first. So, -3 * -3 is really -3 + -3 + -3 = -9, and then -(-9).

 

[raven]

Go easy on her, as she’s an outcast from her tribe...

this is the normal state for INTJs

An absolute truth! Explains alot of my life.
Had no idea I had a reason, must be why I'm on TB

A negative 12 is not a “lack of” 12.

If you add 12, the “lack of” 12 sucks the 12 into itself, giving you zero. Is that right?

 

[Profit of Doom]

Are there any high IQ friends of AOC out there following that could come up with the important answers?

High IQ and friends of AOC are non-overlapping sets.

If you subtract all the even numbers in an infinite list of numbers, do you still have infinite amount of numbers?

1,2,3,4,5,6,7,8,9...

1,3,5,7,9...

Yes...even though you “subtracted” an equal amount of numbers!

Yes, it’s just a smaller infinity.

 

[To-late]

No, because subtracting a negative from a negative takes you further negative.

Nope I said 'like'.
"Now, if you're adding a negative, you can regard this is pretty much the same as when you were subtracting a positive, if you view "adding a negative" as adding to the left. That is, by plus-ing a minus, you're adding in the other direction. In the same vein, if you subtract a negative (that is, if you minus a minus), you're subtracting in the other direction; that is, you'll be subtracting by moving to the right."

 

[Profit of Doom]

No. My question would be akin to “why is down down?”

Because you are dropping a hammer on a planet with positive gravity.

 

[Blazen]

It's MAFFS. Maffs beez hard.

Unless youvs gone be a docta.

 

[To-late]

If Fred owed you $1000 and you owed Fred $500, you owe Fred -$500.

Correct!

 

[Profit of Doom]

OK, you have two dead cats (negatives).

You multiply them by two other dead cats (more negatives).

You then have four dead cats who are really alive over the Rainbow Bridge (positive).

There you go.

How else would I have known they are there?

Schrodinger’s cat

 

[Profit of Doom]

OMG . . . an actual, real life, female INTJ . . .

We should have her bronzed.
Or make her queen.
I would say save her for breeding, but that would probably get me slapped, and for good reason.

 

[mzkitty]

Schrodinger’s cat

Well, let's see...... I cleaned the litter boxes of:

Sharon
Kitty
December
Tuesday
Persia
Annie
Dali I
Dali II
Tiger
Mitty
George Hitler, Louise, Gwenavere (roommate's cats)
Marina
Kitteny
Davie
Judy
Baby

And others.

They were real cats who have crossed the Rainbow Bridge.

I have not cleaned the litter box of Schrodinger's cat since he was a double negative.

when you are an INTJ, lots of people want you Bronzed
. . . and other horrible things having to do with super heated metal . . .

Here's another for you folks.

Lets say: b = a
multiply both by a, and you get: ba = a^2
subtract b^2: ba - b^2 = a^2 - b^2
factor: b(a-b) = (a+b)(a-b)
divide both sides by (a-b): b = (a+b)
since a = b (first statement): b = b+b
or
1 = 2

Well, since a = b, when you divide both sides by (a-b), you are dividing both sides by zero. So what you really get is infinity = infinity. Definitely a true statement, LOL!
