Is and equal to as well as?

雖然and和as well as都可以解作”和”或”以及”
但兩者是不同的
and連接的名詞或動詞，在文上，地位是相等的，如：
Peter and Mary were sick yesterday（我們可以看到，動詞是用複數形）
但as well as卻只可以看為附帶說明，所以和主詞連用，卻不屬主詞的一部份，如：
Jane, as well as Mary, was sick yesterday（我們可以看到動詞是用單數形）
希望幫到你！

Not exactly.

Example 1 :

He gave me money as well as advice.

(Not only he gave me money but also advice)


Example 2 :

He gave me money and advice.


I hope you can see the difference.
