But how many points in grammar trolling?
"I have 2 moneys" doesn't make sense, so you use "less money."
"I have 2 points" does make sense, so you use "fewer points."
"Fewer rational numbers" works, but "less real numbers" sounds funny.
Might be my own ignorance, might be my teachers growing up using trainwrecks like "yous" and "alls."
