To solve this question, we first need to know how to use certain letter in the phone. For example, in the case of letter C, we can observe it is on the number 2 of the phone.
Therefore:
C= 2
P= 7
K=5
I= 4
E= 3
H=4
L=5
T=8
Q= 7
A= 2
F= 3
M=6
J=5
Y=9
B= 2
N= 6
[tex]\begin{gathered} -C.P\text{ - \lparen-K.I\rparen= -2.7 - \lparen-5.4\rparen= 2.7} \\ \frac{E}{H}+\text{ \lparen -}\frac{L}{T})=\text{ }\frac{3}{4}\text{ - }\frac{5}{8}=\text{ }\frac{24\text{ - 20}}{32}=\text{ }\frac{4}{32}=\text{ }\frac{1}{8} \\ Q.A\text{ + \lparen-F.M\rparen= 7.2 - 3.6= 3.6} \\ \frac{J}{Y}\text{ -\lparen -}\frac{B}{N})=\text{ }\frac{5}{9}\text{ + }\frac{2}{6}=\text{ }\frac{5}{9}+\text{ }\frac{1}{3}=\text{ }\frac{15\text{ + 9}}{27}=\text{ }\frac{24}{27}=\text{ }\frac{8}{9} \\ \\ \\ \end{gathered}[/tex]The four-digit code is composed of the numbers in the red dash line. Therefore:
2839
The answer is 2839.
