"With", "Like", "As Well As"

"With", "like", and "as well as" are prepositions that if words joined to a singular subject by these prepositions, they always take a singular verb.

Examples:

Peter, with his friends, is in the class.

The boy, like the father, has curly hair.

Emma, as well as Anna, is playing with dolls.

The singular verbs in the examples above are in red.

But beware of the following example: Peter and his friends are in the class.

If preposition "and" is used, a plural verb is applied.
