 ### Problematic code:
 
 ```sh
-[[ "{$var}" == "value" ]]      # Swapped around $ and {
-[[ "$(cmd1) | cmd2" == "42" ]] # Ended with ) too soon
-[[ "$var " == *.png ]]         # Trailing space
+[ $var+1 == 5 ]              # Unevaluated math
+[ "{$var}" == "value" ]      # Swapped around $ and {
+[ "$(cmd1) | cmd2" == "42" ] # Ended with ) too soon
+[[ "$var " == *.png ]]       # Trailing space
 ```
 
 ### Correct code:
 
 ```sh
-[[ "${var}" == "value" ]]      # Correct variable expansion
-[[ "$(cmd1 | cmd2)" == "42" ]] # Correct command substitution
-[[ "$var" == *.png ]]          # No trailing space
+[ $((var+1)) == 5 ]          # Evaluated math
+[ "${var}" == "value" ]      # Correct variable expansion
+[ "$(cmd1 | cmd2)" == "42" ] # Correct command substitution
+[[ "$var" == *.png ]]        # No trailing space
 ```
