Understood. So using that method, would the following be correct?

#15?
でもサッカーをするのがあまりじょうずじゃありません
However, I am not very skillful at soccer.

I also have a question regarding the use of 'みる' found in my text book:

これからみにいきましょうか
Shall we go to see them now?

I've noticed you use 'みるに' rather than 'みに' for sentences like this. Could you explain to me why this is? (Just for clarification, the Japanese dialogue in my book is written in romaji, so it is definitely using 'mi ni' rather than 'miru ni'.)

As always, many thanks!
