I am trying to manually add the NPV formula but I am getting the error message Error: attempt to apply non-function

npv<- (2520/(1 0.10)) (2520(1 0.10)^2) (2520(1 0.10)^3)

Please let me know why am I getting this error message and how can I fix this?

Probably, we need the *

(2520/(1 0.10))  (2520*(1 0.10)^2)  (2520*(1 0.10)^3)
