Hi, my favorite lesson at school - mathematics. So cool that it is an exact science. So we told the teacher. On this subject I have great grades. After all, you just need to include logic and think a little. But I admit it was difficult with the formulas. But now I'm used to, and all very good. I would like to say a huge New Year's Eve to those who came up with the math, because it will help us in all of life ...
