I won't correct your math but I'll assume you've thrown the door open to any other corrections? Below are some apostrophes. Feel free to copy and past them liberally throughout your next post, obviously your keyboard is damaged: ' ' ' ' These are commas, <--- Throw those in anywhere, please. Anywhere you like. At least one, now and again. Finally, exclamation points and question marks should be treated like ex-wives. One is enough. Two is one too many. Three is excruciating.
