What is 9+10 you ask? Perhaps you fancy asking these ridiculous questions? You must pardon me but I must inquire as to how such a folly natured problem had stumped you enough that you had to pose such a question. You absolute buffoon, you fool. If you insist on inquiring such a question from me then I suppose it cannot be helped. A numeric expression such as 9+10 can be solved in numerous ways to which I am baffled as to how you, someone I presumed to be possessing some degree of intelligence, were incapable finding one. I will illustrate one method. By employing place value, one could simply enlist the use of one fingers. Granted as long as you knew how to count, and by God's name I hope you do but it seems unlikely at this point, you would easily reach to the sum answer of 19 by working your way up. I must bid you farewell and please, come to me with these foolish questions no longer.
