Cash Flow Accruals

CFA Mock question 38 indicates cash flow accruals as NI-(CFO+CFI) Schweser quick sheet has NI - CFO-CFI , I got this question wrong as i added the CFO and CFI since CFI was (double) negative anybody know whats up with this?

dude you cannot post those questions on here it is an ethics violation. did you not read that section at all?

should we ban this bum?

NI - (CFO+CFI) = NI - CFO - CFI.

Expect one of the two to be negative for that reason
