I wrote an essay and returned it to my teacher who told me that it was perfect except for that one mistake with the usage of there are:
There are currently 192 218 546 ways to set up..."
She marked it as incorrect. She told me that I should use "is" in lieu of "are".
As I am pretty sure that I have it the right way, I decided to ask the community here this question. I find this community is the most accurate and by far the friendliest.
