2+2+2/2=5
ReplyDeletethats 4 2's retard look at my answer from june 6 2012 for right answer
Deleteur mean!! you cant talk to people like that!!!
Deleteand its 2+2+2+2+2/2=5
DeleteHe the mean anoymous person u can only use 2 2's
DeleteThere's actuaaly a really simple way of doing it. 2 SQUARED = 4, HALF OF 2 IS 1, 4 + 1 = 5
DeletesEE? sIMPLE!!!
lolololololololololololol
Deletehey two above me...that would still take 4 2's 2(2)+2/2=5
Delete(2/2)+2*2
DeleteOmg you lot are over thinking this EASY riddle! 2+2+1=5
Deleteyuo cant use 1 only 2's
Deleteno .... u can use any thing:):
Deletecause it said U CAN ONLY USE TWO 2SAND ANY MATIMATICAL SIGN FUNCTION OR SYMBOL
Deletethe answer cud be 2+2+6-5 too
Delete2/2 + 2^2
Delete2+2+2+2+2/2=5
DeleteSqrt(.2^ -2) = 5
DeleteHolly :P
PEMDAS. Division First.
Delete2+2+2/2=5
So its
2+2+(2/2)=5
2+2+1=5
Smart one @First comment
rely this is easy 2+2+2+2+2/2=5
DeleteYour are incorrect because you do divison first
Deleteso it is (2+2+2+2+2)/2=5
2 divided by 2= 1
Delete2x2=4
4+1=5
2+2+2/2+2=5
Deleteim in fifth grade and this is easy...
Delete(2+2+2+2+2)/2
The answer is 2+2+1 = 5 it says only using two 2's which I have, doesn't say i can't use any other numbers. They guy up from here who put this is right
Delete2+2+?=5 2 plus 2 plus what gives you 5?
Delete2*2 + 2/2 = 5
ReplyDeleteremember that time when the question said USE TWO 2s
DeleteThats three twos, squared doesnt count as a 2 because its a mathmatical function
Deletethe correct answer is:
DeleteNO!
the question is if you CAN make it but you cant!
everyone is over thinking it you have to really read it carefully!
2*2 + log(e) = 5; where e is eulers number.
ReplyDeletelog(e)/.2 = 5;
2^2 + 2/2 = 5
ReplyDeleteAndy
four 2's so you're wrong and you just copied someone else..
Deleteyour being really mean...please dont talk to people like that.thank you.
DeleteThis comment has been removed by a blog administrator.
Deletethe answer is 2/2+4=5
Delete2^2 + 2/2 = 5
ReplyDeleteAndy
(.2 ^ -2)
Delete:\
.2 just means 0.2, it isn't actually a function rather a short way of righting/typing 0.2. I don't know why the answer says to be honest...
Delete*writing. My bad :p
Delete(2+2+2+2+2)/2 = 5
ReplyDelete{[(2+2)*2]+2}/2 = 5
ReplyDelete(2+2)+(&/&) &=infinity sign
ReplyDeleteinfinity is not a "mathematical" sign, function, or symbol...
Deletethe infinity SIGN is!:):
DeleteAnd &/& is not always 1! can be 0, 1, or & or whatever you want ... even undefined!
DeleteSquare root ((.2)^(-2))
ReplyDelete1/5 and negative two are not 2
DeleteNo...he got it right.
Deleteno he didnt got it it 25 still not 5 :P
Delete.2 is just short for 0.2
Delete(2*2)-(2/2)+2
ReplyDeletesq.root of(2+2)! , using the greatest integer function
ReplyDeletewhere ! means factorial
only 2 answers correct..which part of only two 2's do people not understand?
ReplyDelete@admin
ReplyDeleteis my answer correct???
(22 - 2)/(2 x 2)
ReplyDeleteOR (2+2)+(2/2)
ReplyDeleteThe correct ans shud b yes bcoz de hv asked 2hether. Can make it nor ot
ReplyDelete2+2+2+2+2/2=5
ReplyDeleteu guys make it so complicated just do
ReplyDelete(2/2)+2+2=5
you can only use "two 2's" moron
DeleteYo dude chill with the insults seriously.
Deleteya what he said!!! if you dont like what people are saying either tell them politely or just get off.
DeleteThis comment has been removed by a blog administrator.
Delete2/2+2+2
ReplyDeleteits NOT the answer.. its been posted 10 times.. and you're stupid
Deletedude you really gotta take a chill pill
Delete(2+2) + "the minus sign - turned vertical to make it a one...
ReplyDelete& this guy is a non-certified genius!!!
Deletethats not nice... i dont know what your problems are but dont take it out on these innocent people!
Delete2*2*2+2/2=5
ReplyDelete2.5+2.5 OR 2.5X2
ReplyDelete(2.5X3)-2.5
ReplyDelete2+2+one=5
ReplyDelete2+2+1=5
ReplyDeleteafter all you said use only 2 two's , you didnt say dont use other numbers
:0
p.s. and Anonymous insulting freak stop being mean to people , come on lets see if u know the answer , go on tell us the answer , if ur the smart guy around here!!!!!!!!!!!!
ONLY TWO 2's are given.
Deleteplease stop getting imaginary numbers from your mind to get the answer 5...
i think (.2 ^ -2)
ReplyDeleteno thats incorrect, but...... HEY!! if you
Deletetake the square root of (.2 ^ -2) = 5 !!!!!!!!
GOOD JOB DUDE!!!!
(2+2+2+2+2)/2=5
ReplyDeletehow can you get it wrong!
I thought you were only aloud to use two 2's though... I'm a little confused ._.
Deleteusing c/c++ operator it should be..
ReplyDelete++(2+2)
or (2+2)++
hey dude i dont no the correct ans so plzzz say me the ans................... :D
ReplyDeleteSQRT(.2 ^ -2)
DeleteTake .2 and raise it to the power of -2 and then take the square root.
hehehe It still 25 not 5 :P
DeleteSQUARE ROOT!!!!!
DeleteThe dot in .2 isn't a function, its just short for writing/typing 0.2
DeleteThis is my way, which is quite easy actually. 2 squared is 4, half of 2 is 1, 4 add 1 = 5. See????
ReplyDeleteceiling(sqrt(22)) = 5
ReplyDeleteWow how are people missing (2*2)+ (2/2) = 5
ReplyDelete.... its clearly 2^2+1...
ReplyDeleteThere are many combinations using multiple numbers (2^2 + (2/2) using 3 or 4 numbers, depending on how you're counting them). I can only think of 2 + 2 = 4 having 5 symbols.
ReplyDeleteactually many people are confused here regarding the no. of 2
ReplyDeletewe can only use the numeral 2 twice .......
my answer is square root of 22 and then placing the value in least integer function
maths guys know what least integer function is and for other people plz google the term for clarity!!
and in the question it is given that we can use functions too!!
and feel free to correct me if i am wrong!!! :-)
solution :
DeleteSQRT(.2 ^ -2)
Take .2 and raise it to the power of -2 and then take the square root.
hey fool thats .2 not 2....
DeleteAnd a '.' is a Mathematical symbol. YOU fool. read the question bell-end
DeleteA . isn't a function, it just means its 0.2 not 2.....
Deleteeasy its 2+2+?=5 make it an equation...
ReplyDeleteyou're gonna PROVE that two 2's become 5.
Delete2+2+n^(n-n) = 5
ReplyDelete2+2+n^(n-n) = 2+2+N^0 = 2+2+1 = 5 .. because any no. that has exponent is 0 is equal to 1 :)
Deleterodolf rimando .. :)
Deleteno you can't. 0 is not given.
Delete2+2+2+2+2=10/2=5

ReplyDelete(2+2+2)/2 + 2 = 5
ReplyDeleteEasy 2•2+2-2/2.
ReplyDeleteClearer: 2 x 2 equals four
4+2 equals six
2/2 equals one
6-1 equals 5!
Oh only two twos then 2^2 + 2^-1
ReplyDelete2•2+x, invisible one but it might also get you 4x.
ReplyDelete(2+2+2+2+2)/2
ReplyDeleteok here it goes:
ReplyDeletea, (((2*2)+2)/2)+2=5
b, ((2+2+2)/2)+2=5
c, (2+2+2+2+2)/2=5 the most direct
multiply by an odd number to get an od result.
ASCII
ReplyDelete2+2+pi/pi=5
ReplyDeleteIts not hard it took me 2 minutes
ReplyDeletesquare root(0.2^-2)
2 Squared + 2x.5=5
ReplyDeleteI wonder y people are saying 4 2's and such. Not many ppl figured it out "_
ReplyDeleteHow do you do it?!?!?
ReplyDeleteint(tan(2)/cos(2))
ReplyDelete2!+2=5 !=factorial
ReplyDelete1+2+2=5
2factorial+2
factorial means to add every number to the number you factorise e.g. 2!=1+2
sorry but factorial is means to multiple all the numbers up to that number. for example: 5!=5*4*3*2*1=120 and 2!=1
DeleteA complex way could be -
ReplyDelete|[-(e^2 - 2)]|
where [] represents greatest integer function.
and | | means modulus.
0. there r 0 ways.
ReplyDeletei meant zero.
Deleteor one. it doesnt ask what.
2squared plus the square root of 2
Delete2 square x 2 + 2 / 2 = 5
ReplyDeleteI think my answer is more creative. it is: 2^2-e^(i*pi)=5
ReplyDeleteI think your answer is the only correct one lol, because .2 is just short-hand for 0.2, which isn't technically the no. 2
DeleteSo hats off to you :)
5-2+2=5
ReplyDeleteSqrt(.2^ -2) =5
ReplyDeleteHolly :P
Sqrt(.2^ -2) =5
ReplyDeleteHolly :P
2^2 + 2^0
ReplyDelete3 twos :(.
Delete2+2+2+2+2/2=5
ReplyDeletei believe you said use only two 2's and blar.. blar.. blar... mathematical symbols. Now I am probably incorrect but is a symbol another word for a number. Probably not but worth a try.
ReplyDeleteSo 2+2+1= 5.
Do not have a go at me if I am wrong after all I am only 12
The answer to this riddle "yes". Is does not ask you "how many 2's" or to write it out. It's a simple "yes" or "no".
ReplyDeleteAnd yes I realise that this is not the author's answer. The author did not ask the question correctly.
DeleteThis is mostlikely cheating but meh...
ReplyDelete2X=2
X+X+X+X+X=?
2.2x2.2=4.84 which would be rounded up to 5
ReplyDelete2+2≈5
ReplyDeletehaha :D
Deletewhat about int(sqrt((2+2)!))) ?
ReplyDeletewhere int means "nearest integer" or "round" and can be replaced by symbols which I'm too lazy to type (and qsrt means, of course, square root, same story for symbol!)
2+2+1 is one of the many correct answers because it says that you can use two two's not "you can't use one"
ReplyDeleteYou can ONLY use two twos....
Deletei hate math.
ReplyDelete2 Square + 2^0 = 4+1 = 5
ReplyDelete22-2=20/2=10/2=5 thats the ans needed
ReplyDelete2+2≠5
ReplyDelete2/2+2+2=5
ReplyDeleteOnly ONE person before me put this, so (2^2)+(2^0) = 5
ReplyDeleteAlso, (2+2)+(pi/pi)=5 & (2^2)+(pi/pi)=5
OR, (2+2)+(x/x)=5... where x is any REAL integer other than 0.
Also using ONLY ONE #2, Inverse of .2 -> .2^-1=5
Using NO 2s... (pi/pi)+(pi/pi)+(pi/pi)+(pi/pi)+(pi/pi)=5
IF you will stand by the nonsense of 'Oh but "^2" (squaring) is considered a 2!!' Then you're better off mentioning that there's a 0 in "^0". Also realize that taking the sqrt of something 'simply means' to take it to the power of .5 ( sqrt(2) = 2^(1/2) = 2^.5 ) and that 'multiplication' is 'simply' short for adding a number to itself an x amount of times (1*3 = 1+1+1).
If you're not math savvy, then stay literal with 'It's a yes or no question to see if YOU have an answer' and just say NO. Too many wannabe smart-asses thinking they're being clever when they just don't understand basic and simple math concepts.
INVERSE, SQUARING, SQRT, & EXPONENTIALS ARE FUNCTIONS!
DECIMALS AND PI ARE SYMBOLS! So all of these OBVIOUSLY fall within the confines of this riddle.
2+2+(2/2)=5
ReplyDeleteits so easy guys.... you guys are dorks. its obviously 2+c over w = m+2 over q -himps =5,,, jk 2+2+?=5 is it that hard?
ReplyDeleteIt's possible to do it like this:
ReplyDelete(((π + π + π + π + π)x2)/π)/2
= 5
2 to the 5th power divide by 2
ReplyDeletewhat about 2.5+2.5=5
ReplyDelete2+2≠5.
ReplyDeleteDone.
