（单词翻译）

When I was a kid I was top of the class in maths. I was really good at mental arithmetic and doing sums. Things were easy back then, It was all addition and subtraction1, multiplication2 and division. I knew my times tables like the back of my hand. Then, things got difficult when I was about 14. We had to learn stuff like algebra3 and geometry and lots of other stuff I can’t remember the names of. Suddenly. I wasn’t so good at maths any more. I think there were a few reasons for this. One was my maths teacher, another was because I sat at the back of the class, and another was I talked a lot. I still like maths and know I would be good at it again if I studied. I did statistics when I was at university and loved that.
