 You want to check whether a number is divisible by any of a set of numbers:
 
-    say 42 %% <11 33 88 55 111 20325>; # OUTPUT: «True␤
+    say 42 %% <11 33 88 55 111 20325>; # OUTPUT: «True␤»
 
 What? There's no single number 42 should be divisible by. However, that list has 6 elements, and 42 is divisible by 6. That's why the output is true. In this case, you should turn the C<List> into a L<Junction>:
 
-    say 42 %% <11 33 88 55 111 20325>.any;# OUTPUT: «any(False, False, False, False, False, False)␤»
+    say 42 %% <11 33 88 55 111 20325>.any; # OUTPUT: «any(False, False, False, False, False, False)␤»
 
 which will clearly reveal the falsehood of the divisiveness of all the numbers in the list, which will be numified separately.
