FRA Reading 28 p.446

On p.446 in the calculation of cash flow accruals the book states: 2007 Profit from … …11,382 Operating Cash Flow…(13,439) Investing Cash Flow…15,753 Cash Flow Based Accruals 13,696 Since the formula for cash based accruals is NI - (CFO + CFI) the result should have been 11,382 - (-13,439 + 15753) = 9,068 Is there an error here or am I missing something? Thank you

My fault! They deduct the amounts, thus the Operating Cash Flow is 13,439 and not (13,439).
