Thank you, master tunci, for your addition

Should we go on with math in Turkish? 

Değil can be conbined with yok:

Bunu bilenler yok(-) değil(-) =>var (+) 

Değil also used with positive words and the result is negative:

Böyle bir şeyi daha önce görmüş(+) değilim(-) => görmedim(-)

conjunction ne ... ne (with verbs) has the same effect as değil. 

The following sentences are positive in appearence but negative in the meaning:

Ne aradı ne sordu

ne(-) aradı(+)  ne(-) sordu(+) => aramadı (-) sormadı (-)

Ne gelen ne beklenen var

[ne(-) gelen(+) ne(-) beklenen(+)] var(+) => gelen de yok(-) beklenen de(-)

(-*+/ -*+)*+ = (- /-)*+ = -/- 

(to be continued) 

Master Scalpel +, good maths again..

The sentence below in past tense consists of some sort of  maths..

Çay sevmediğini [-]  söylediğini [+] duymadım [-] -->  Çay seviyor. [+]

[ I havent heard him saying that he doesnt like tea. --> He likes tea ]

 [-] * [+] * [-] = [+]

-------------------------------------------------------------------------------------

Çay sevmediğini [-]  söylediğini [+] duydum [+] --> Çay sevmiyor [-]

[ I have heard him saying that he doesnt like tea. --> He doesnt like tea ]

[-] * [+] * [+] = [-]

Yes, it´s mathematics. Addition and subtraction to be exact.

This turned out into a very interesting thread.

I can think of one occasion where in Turkish (-) + (-) doesn´t make (+). hiç + -ma- is double negative but it´s still negative.

ne can change a positive sentence into a negative even when not repeated in one sentence :

ne(-) gereği var(+) => gereği yok(-)

böyle bir şeyi kabul etmek ne(-) mümkün(+) => mümkün değil(-)

The word kim may have the same function as ne:

Böyle bir yerde kim(-) yaşamak ister(+) => kimse istemez (-)

When to use Hiç [-] + Yok [-] = -

 (-) + (-) does make (-).  

 Evde hiç [-] tuz yok [-] ---> There is no salt at home at all. [-]

Hiç kusur yok = kusursuz

Hiç kusursuz değil = kusur var

Hiç zor görünmüyor = kolay görünüyor

Hiç kolay görünmüyor= zor görünüyor...

Is it really easy? Or are my examples too simple??

I think they are cool examples..Aferin sana !

Abla,  (-) + (-) makes (-) even in the north pole I am talking about multiplication (not addition) and I didn´t ever give examples with "hiç". Tunci´s examples with "hiç" has nothing to do with what I am trying to say here. Examples like "oraya hiç gitmedim", "evde hiç tuz kalmamış" and so are of the subject of the ordinary negative sentences in Turkish. I just wanted to give a specific info about how we form negative sentences with positive words and positive sentences with negative words and it is not a thing that can be applied to all type of Turkish sentences. At last, we have firm ways to form negative and positive sentences. The thing I am trying to explain here is that by using mi, değil, ne, kim we can form negative sentences from positive words and positive sentences from negative words...and that´s all...

Ok, scalpel, I am sorry.
