I was told 1+1 does not equal 2? Special circumstance or smthing?

Question

Someone told me it was beyond calc and diff. eqs. I'm just working on Calculus right now, but
1) Is this still in the base 10 system?
2)is it in cartesian coordinates?
3)is it some special circumstance(like modular arithmetic)?

I wonder if you guys could help me out here.

I DONT CARE ABOUT BINARY I know about various tricks you can use to make it seem as if 1+1=3. But I was wondering about actual systems, i.e. non-Euclidean geometry.

Answer 1

Some id**t came up with this on Y!A a while ago.

Help is on the way - LOL!!

1+1=2 - - - -PERIOD!!

These id***s can use math terms and messed up ideas to justify the existence of such and idea of 1+1 equalling other than 2. Time-wasters(being nice here). They should find better things to do with what seems 'fertile' minds(gone wrong)!!

Perfect examples are right before your eyes above this dissertation!!
Just has to find a way to mess with reality(+ this and + that OY - 'tis to throw up!!). (61,000plus points - strapped into the comp. chair day and night!!). I'm retired and dabble, this guy's GONE FISHIN'!!

I gotta say this(honestly) - my percentage of 'best answers' is higher!! Now I will say, as I often do - 'NUFF SAID!!

Thanks for the almost immediate 'thumbs up' - generous of you!!

Good grief - the door is ajar at the 'farm'!!

'andrea_...' my poor, poor girl!!

Here goes - - !!

You tell us a=b(OK!). Then you tell us a+b=ab(not!!)
a+b=2a or 2b(yasser!).

ab is a times b(right!!).

Then you actually state that ab=2b(not!)(a times b - yes).

THEN we get - a+b(a-b)=a(a+b)!!! OY!!
(a-b)=ZERO(according to you!!)
Thus the above problem equates to ZERO=a positive number(Impossible!!).

So is (a-b)(a-b)!! ZERO, That is!

To get this over with, YOU say a=1, thus b=1, thus 1+1=1 !!
First, as requested by the asker and answered by yours truly, 1+1=2.....PERIOD!!

What if a or b - meaning the same thing(in your thesis) was not 1 BUT 2, or 3, or4 or whatever - the man in the moon!!
Mr. Jones must be off his roc**r!! OR you jest mightily!! what a cr*c of doo-doo!!

Answer 2

this was posted above:
________________________________
showing the variable values:
let a=b
a+b=ab
ab=2b

the equation:
a+b(a-b) = a(a-b)
------------ ---------
(a-b) (a-b)

a+b=a
If a=1, b=1
1+1=1
________________________________
this is why you check, just sub a one in the original equasions


the equation:
1+1(1-1) = 1(1-1)
1+1(0)=1(0)
1=0 <--------------FALSE

given the constraints of the conditions
let a=b
a+b=ab
ab=2b

1=1 TRUE
1+1=1(1) FALSE
1(1)=2(1) FALSE

in the equasion, and the conditions, 1 is not a possible solution.

TRY 0

let a=b
a+b=ab
ab=2b

0=0 TRUE
0+0=0(0) TRUE
0(0)=2(0) TRUE

a+b(a-b) = a(a-b)
0+0(0-0)=0(0-0)
0=0 TRUE

the only number that correctly satisfies this system is 0


1 apple, you have one apple
another one, you have two
1+1=2

if you base 2 how you represent the number, it still means 2, even though it's written the same as ten in a ten base

if you had 1 million apples, it takes more digits to represent the number in base 2 than in ten. In base 1(11111=5)you need 1 million digits! dose that mean we have fewer apples if we write 1,000,000? no

it takes a weak mind to think of these tricks as legit. math.


MARK B, you hit it on the head!

Answer 3

It's not base 10. In binary, it's 10. I don't think it's geometric, because it would be a set of numbers plus a set of numbers (x, y) + (x, y). Also, 1+1 in time is still 2. It has to be binary because in any base beyond that, it's still 2.

Answer 4

On base 3 for example, 1+1 = 2 still, but 1+1+1 = 10
On base 2, 1+1 = 10. Since the number "2" per se does not exist!

Answer 5

In binary (base 2) 1+1=1

in binary the + sign means the word "or", since there is at least one number 1 that means

1 (or) 1 =1

Answer 6

In binary arithmetic, 1+1 = 10. There are other games that one could play; example: at 45 degrees north latitude (for example), if you go a mile east and then another mile east, you are slightly less than two miles from your original position.

Answer 7

I don't know how to make 1+1=3, but a math teacher taught me how to make 1+1=1.

showing the variable values:
let a=b
a+b=ab
ab=2b

the equation:
a+b(a-b) = a(a-b)
------------ ---------
(a-b) (a-b)

a+b=a
If a=1, b=1
1+1=1
