Hey, I'm not 100% sure what you mean by how; but hope this helps. When you tweet something Tweeter allows for a max of 140 characters to be typed. So that's what MAX_CHAR represents. Then, you want to show the user the number of characters they have left to type which is done with the getRemainingChars function. This function will get mText, which is the text(tweet) the user is typing, and with the .length method it will tell how many characters the text currently has. Substract 140(MAX_CHAR) from the mText char length and you will have the remaining characters to type!

Not sure if that answers the question, if not you could be a bit more specific and maybe I can help further. Good luck!
