I know this is a quite general question, but I've been wondering what are the differet ways to say 'to add'. 'To add' is a very useful word for everyday use, but I find it quite tricky to find the correct japanese equivalent since there are diffenret words for different circumstances. What I mean by this:
二つの数字を足す。To add two numbers together.
塩を加える。 To add salt.
あと2000円かかります。2000¥ will be added to your bill.
もう一つ付け加えます。To add (to that).
There is also '追加する' and '加算する' , which I'm not sure how to use.
How do I use '追加する' and '加算す'?
Are there any different ways to say 'to add'?
What are the differences between them? (Please show on a sentence.)
Thank you so much in advance.
