Is guess and check the only strategy you can use?

Sam said...

If anyone needs help getting started try to figure out what I is there's a big clue in the letters because it spell NIP twice.

lets say the numbers are 1-9 do have to use all of them or can u not use some of them can u use 7 of the nine like lets say i use 1 2 3 4 7 8 9 can i do that or do they have to be in order like 1 2 3 4 5 6 7?

Sam said...

Ben there are only 7 different letters N,I,P,A,O,C,and R. Each letter stands for a different number, so every N is the same every time. Also there isn't a set of numbers you have to use just as long as when you multiply them every N is the same and every I and so forth. So no you don't have to use all the numbers 1-9 and you can't anyway.

i meen lets just say there are 7 numbers
i think i got the answer but at the end one of the numbers is over 7 its 9 so i used 1 2 3 5 6 7 9 these are the nine numbers i used
if it works with these nine numbers is it ok or does it have to be 1 2 3 4 5 6 7 and not 1 2 skip a few?

"I" must be 1 because Nip times "I" equals NIP. So the problem now is
N1P
X 1N
ANON
N1P
CORN

Danielle said...

The letter "i" cannot be 0 because then it would have to be a 1-digit number.

Yacova said...

i think "i" and "p" is one because pxn=n and ixn=n as well

Yacova said...

wait nevrmind about i being one...sorry

Yacova said...

n is either 5 or 6 because nxn = an so 6x6=36 and 5x5=25

Anonymous said...

thats wat i thought yacova but htis is wat i always mess up with a prblem like this i always think its 1 but dont forget if n=5 and p=3 the 1's digit in 15 is 5 so n on the bottem is 5

GREAT comments!
I does indeed have to be one since I x NIP = NIP.

Allen said...

I think that the only way to solve it is guess and check and maybe working backwards

Allen said...

no nevermind not backwards

jaren said...

i and n together has to be a two digit number because if i equals one then n and i would equal n but it doesnt it equals o

gavriella said...

mrs cooper,
why did my other comment post as Jaren??

Ethan said...

does the nip under anon mean to add them together because there is no sign

Danielle said...

Yeah, you definitely have to use guess and check.
I think P=1 because because NxP=N.

Anonymous said...

p is not 1 what if u do n=5 and p =3 that works to i=1 because it says i times nip =nip just trust me

Mrs. Cooper said...

YES, N I P under A N O N does mean to add them together because this IS a two digit multiplication problem.

Yardi said...

N has to be a number that can be divided and can get one number that's the same as the last digit of the number right? Because let's say that N= 8... so then P = 6 so if 6 times 8 = 48 then N's last digit is 8 and 48 and 8 are the only numbers who can do that.

Yardi said...

If you read my last note you could figure out now half the problem becuase P = 6 and so its ??6 times ?8! Aren't you happy I went on the blog. I hope you can understand what I said on my last one

Yardi said...

Wait so then if I equals 1 then the problem is now
N16
X 18
------
ANON
N16
-----
CORN

Yardi said...

i MEST UP ON MY LAST NOTE, IT's supposed to be:

816
x 18
-----
A8O8
816
-----
COR8

Yardi said...

nevermind ignore that comment... it's not right

i really hate these types of problems...

Ethan said...

n+a added together can't equal more that 10 because then corn would have to have 5 digits

Ethan said...

n+a added together can't equal more that 10 because then corn would have to have 5 digits

Ethan said...

does p have to equal 1 so 1*n=n

Ethan said...

n has to equal 5 because i am pretty sure that 5 is the only number that after its first 10 multiples, has the ones digit repeat itself. ex: 5*3=15

Iris said...

I agree with Ethan that A plus N can not sum up to 10 or anything more than that or else CORN would have 5 digits instead of 4.

Iris said...

N has to be a number that when is put to the power of 2(Multiplied by itself), equals a number with two digits(AN)

since tomorrow we disuss this ill just say wat i think is the answer n=5 p=3 i=1 a=2 o=6 r=9 c=7 is it right or wat

Mrs. Cooper said...

I like most all of your comments. They were very helpful!
