-## Remove '$' or use '_=$((expr))' to avoid executing output.
+## (Message goes here)
 
 ### Problematic code:
 
-    i=4
+    (Simple example of problematic code)
-    $(( i++ ))
 
 ### Correct code:
 
-Bash, Ksh:
+    (Simple example of above code, only fixed)
-
-    i=4
-    (( i++ ))
-
-POSIX (assuming `++` is supported):
-
-    i=4
-    _=$(( i++ ))
-
-Alternative POSIX version that does not preserve the exit code:
-
-    : $(( i++ ))
 
 ### Rationale:
 
-`$((..))` expands to a number. If it's the only word on the line, the shell will try to execute this number as a command name:
+(An explanation of why the code is problematic and how the correct code is an improvement)
-
-    $ i=4
-    $ $(( i++ ))
-    4: command not found
-    $ echo $i
-    5
-
-To avoid trying to execute the number as a command name, use one of the methods mentioned:
-
-    $ i=4
-    $ _=$(( i++ ))
-    $ echo $i
-    5
 
 ### Exceptions:
 
-None.
