Mathematics Competition

Since I have taken high school and now am basically by wasting my time working at MEGU, I think, as always, very long time. Since I run slowly sick ideas, I ask myself now constantly any math problems.

Today we make a draw, who can answer all the math problems correctly, or at least I can give the breath of correctness wins the silver mathematics price the same traditional games and a new green paint marker Edding, I specially have stolen the raffle from MEGU.

(For information, I have no idea whether those tasks to be solved at all, so think yourself to about it, I status that is no more)
