AGJ corresponds to the digits 0, 6, 9. As a number, this is 069 = 69.
CEG corresponds to the digits 2, 4, 6. As a number, this is 246.
EDB corresponds to the digits 4, 3, 1. As a number, this is 431.
The expression is AGJ – CEG + EDB, which translates to the arithmetic operation:
$69 – 246 + 431$
$69 – 246 = -177$
$-177 + 431 = 254$
Now, convert the result 254 back into a three-letter code using the mapping:
The digit 2 corresponds to C.
The digit 5 corresponds to F.
The digit 4 corresponds to E.
The resulting code is CFE.
