Arithmetic does not tell fortune.

Me too. I really can't do verbal arithmetic, especially if you don't often do verbal arithmetic and change money. I often feel ashamed. I'm afraid my parents say I'm in middle school, especially afraid that I can't find good money. In fact, sometimes I can find a good one, but I am nervous, or I always feel that I have miscalculated, which leads to miscalculation. I don't know why, if my parents are around, I will be more nervous and more.
