Let's calculate it with the help of table.
00:04
Year, cash flow, cumulative cash flow, here 0, 1, 2, 3.
00:21
Negative 1, 0, triple 0, here 9, triple 0, here 3, triple 0, then 1, triple 0.
00:31
Now cumulative cash flow for year 1 is here 1, double 0, double 0.
00:40
Then here when we add 9000 in 10000, so we get negative 1000.
00:55
Again, add 1000 and negative 1000 and 3000 from here, so we get 2000.
01:04
Again, 2000 plus 1000 is 3000...
