A Cipher Ask For Help If You Need I'd Love to see it solved.
A Cipher Ask For Help If You Need I'd Love to see it solved. Ive put it into a pretty simple form so as long as you know basic algebra then I can explain my very obvious typing impadiment.

Mathematicians Cipher
Apples Fall
Useing the information Below find the hidden message:
KyCQLxDIzCGrBEuAGuGtAGo

Key: Is a word or phrase without repeating letters (ex: if the word/phrase happens to be Apples Fall then the key is aplesf)

Index:The Index is a 5x5 box with the key placed in the first top boxes starting from the top left going right followed by the remaining alphabet.
J and k are always paired
With the example key
Apples Fall
the index would look like
a/p/l/e/s
f/b/c/d/g
h/i/j/m/n remember j and k are paired.
o/q/r/t/u
v/w/x/y/z

Values: the values are in the index itself normally shown as a letter. located by labeling the bottom left cell as 1 and the top right cell as 25 so
(ex:
21/22/23/24/25
16/17/18/19/20 (ex: c=18 / v=1 / s=25)
11/12/13/14/15
6/7/8/9/10
1/2/3/4/5 )

Rules: the rules are used in the steps for the cipher they must be known and agreed apon by both the sender and the reciever of the message and they are
always uppercase letters.lets use the following rules
A =X+1
B =X+2
C =X+3
D =X+4
E =X+5
F =X(1)
G =X(2)
H =X(3)
I =X(4)
J =X(5)
K =X^2
L =X^3
M =X^4
N =X^5
O =SQUARE ROOT OF X
P =X+10
Q =INVERSE OF X (EXAMPLE AQ=INVERSE OF A SO X-1)

Cipher: to use the cipher is take a message, lets use King as the message and substitute the letters in the message for the values in the index.
and make math problems that would equal the value using the rules.The Rules are always Uppercase letters and the values are always lowercase letters.
K=13 4x2+5
I=12 6x2
N=15 5^2-10-5
g=20 2^4+4
now to make the cipher using the rules and value index
k=4x2+5 make the first number the value.Do this by finding the value in the index (4=y) then simplify the rules x(2)=G and +4=D Then K=DGy
(Notation Function, rules precede the values)
K=EGy
I=Go
N=PQKz
G=DMw

the final message is EGyGoEQPQKzDMw

to decipher the message one must know the rules and the index as you know it now to decipher the message first find the value then use the preceding rules to find true value then substitue the letter from the index for its true value found.. remember the value is always lowercase and the rules are always Uppercase Using N From King--->PQKz=z-->use k--> use inverse of P---> or z--->^2--->-10---> or 5^2-10=15 (15=n)
