[MAHENDEKA]

p { margin-bottom: 0.08in; }

1+1=1
Proof
Let a= 1…………….(i)
Multiply by a in both sides
a×a = 1×a…………..(ii)
From eqn (ii) reduce 1 in both sides
a²-1 = a-1………………(iii)
But a²-1 = (a+1)(a-1) -This is factorization of quadratic equation
There fore
(a +1)(a-1) = (a-1)…….(iv)
Divide by (a-1) both sides
(a+1)(a-1) = (a-1)
(a-1) (a-1)
(a+1) = 1…………………..(v)
But from equation number (i) we let a=1.Take it and substitute into equation number (v)
Hence
1 +1 = 1

I dont see an 'a' in the formula you are trying to prove. Labda ungesema, let 1= a (In which case you would be asuming that we dont know what '1' is but we know what an 'a' is!).

You let a=1,so wen u divide by (a-1),means dat you divide by zero both sides,mathematicaly dis is incorrect and the answer is undefined and not 1 as u show us!

 

[DMussa]

hili ndo tatizo la kudhania hesabu inaendeshwa kwa assumptions....

If you are trying to prove 1+1=1 why are you assuming 1 = a? kwani ukifanya ivo tayari equation yako inakuwa a+a=a so what the hell!?

ulichofanya wala sio hesabu, ni kubadilisha 1kuwa 'a' na baadae kuibadilisha 'a' kuwa 1

BIG NO!!!

The answer Must be true for all numbers

Why?

If I let a=2, sipati 1+1=1

Kwa hiyo kwa maoni yangu hesabu yako ni sawa na maji+maji = ?

Big up Mahendeka, good thinking!
But there are several problems with ur so called proof.
1. Basically what you are doing is NOT proving but verifying that 1+1=1. There are no any analytical tools (theorems, lemmas or conjectures) that support what you are doing!

2. A proof as one of the readers put it must be true for all values ( and not necessarily numbers!) not just for some values. Your arguments are untrue when a<0.

3. The statement let a=1, is equivalent to writing a-1=0, so division by itself meand you are dividing by 0 which is indeterminate form, unless you would have put for a not equal to 1, but which contradicts your assunption that a=1!

However this is good thinking, and that is what maths needs!

Huu utoto awapelekee darasa la saba, very poor reasoning. Kwani wewe hujui kuwa 1x0= 2x0=3x0=4x0......... etc?

....the way i see the problem is the Problem itself. Mathematics is the Study of Numbers only, not letters

 

[introvert]

Mmh.. Ivi unatakiwa u-prove definition au theory?! Au hiyo ni Boolean..

 

[Pape]

lol, very wrong idea...you were you saying 1+1=1?, why did you assume that a= 1? why you didnt assume that 1=a?
