我已经很多年没有再接触数学了,这句话怎么翻译成英语

I have not been exposed to mathematics once again for a great many years.
be exposed to,表示接触某门学科,接触某人,接触某事物等,例如be exposed to art是接触美术,be exposed to sport是接触体育,be exposed to martial arts是接触武术,等等.once again是再、再次、再一次的意思.a great many years也可以写成many years,还可以写成years,意思也差不多,都是很多年的意思.

这里的“接触数学” 怎么翻译是这句话翻译的关键。 有几种说法，但最常用的应该是：
I have not touched upon mathematics for many years. "touch upon" = 触摸，碰见，提及，意思=中文里的“接触”
希望对你有帮助。

I haven't been dealing with Maths for years.
I am having nothing to do with Maths for years.

Math has been unfamiliar with me for a while.

I haven't get involved with maths for a long time.
