because when you have 2 apple and some one gives 2 more. let it become o N . if now some one take 4 of N you remain wiht nothing  
siece 2+2 - 4 = 0  
so 2=2 = 4 not 5 :-)

beccause if 2+2 is 5, then 5-2 must be 2,but u will get 5-2 as 3, so 2+2 is not 5 
now check for 2+2=4, 4-2=2 so the correct answer is2+2=4. ok

u can say 2+2=5

but not on this language it may be in another coding language

u add 2 to the value 2 and got 5 .then subtract the added value 2 from the result if u got 2 then it can be 2+2=5.

perhaps, we can say it is because its mathematics, not the stock market moods.

Just bcoz no one till date has been able to prove that 2+2=5 .The day we get the proof, 2 + 2 will definitely give us 5


  • Aug 11th, 2006

It is not always. dont believe, just see



16-36+(81/4) = 25-45+(81/4)

(4 - (9/2))^2 = (5 - (9/2))^2

taking square root we get

4-(9/2) = 5-(9/2)



       hows that.

its because.......

I I + I I = I I I I

(the number of sticks before the operand n after the operand,when summed together gives all the given sticks put together.......but not 'a stick' more than that were placed............this is true 4 any no: of sticks to the right side n to the left side of the stick.

truncate(2.8) =2 + truncate(2.8) = 2  ==> 4 .

round(2.8) = 3 + truncate(2.8) = 2 ==> 5.

If 1+1=2,

Then 2+2=4.

If 1+1=1.5,

Then 2+2=5.

Use your fingers, that is enough, calculator is not required; Idont think you would get 1.5 or 2.5. Tryit! BEST OF LUCK!!!

it's because addition of any two even number will results in a even no: and not a odd number, so 2+2 cannot be five 

  Was this answer useful?  Yes


  • Apr 30th, 2007

Because 2+3=5, that's why 2+2!=5 thus 2+2=4

dear siddarth..
while taking square root consider both the signs as a^2=(-a)^2
so 2+2 is alwayz 4...

Look - |,|  when we count these lines we say 2 by numbers in english.

' +'  means increament in some amount,  that is by the amount around this + symbol. ie if we write |,| + |,| it will become |,|,|,| which when counted is represented as 4 in english. that's why the result. Because of counting and meaning of symbol which has been universily defined. Thanx

Hope this satisfies.

According to synergy condition its correct but as per arithmetic calculation its wrong. Example for synergy:consider wipro is gaining a profit of 1billion per year and infosys too, seperately, if it both works together definitely it will gain more than 2 billion per year.

According to mathematical calculations, 2+2=4.
But if we talk in general view then we can say that 2+2=5. to prove this statement, take example of a group. If they are united and work together then they can achieve more than their expectation.

the answer given previously for 4=5 is not quite satisfactory because
here when we take square root on both sides we have,
0.707i is not equal to 0.707
so this is not possible so,
4 is not equal to 5

It may be other even number like 6,8,10 its so how can you tell that 2+2=4

All 1 to 9 and 0 are noun... so 2+2 = 4 because basically 4 is a noun.. representing the four thing and 2 also so its a systematic programming of calculation by a nature and denoted by a human in its easiest way.

You are asking a grammatical question and want a mathematical answer, both the things have different principle.. hope you get that
