Look at this picture and tell me the "number value" of the letter O. Then, tell me how you did it. That's it! Pretty easy.
Number value? I don't get it. The picture doesn't have anything that shows values of any letters, or their relations to each other. Is the "stop" inside the "stop" supposed to be the clue? I don't think it is, since the stop sign isn't an O, except in my imagination. So, the only thing the picture is saying is "STstopP! Hotlinking!!" If the stop sign was an O, then "stOp = O"
