Example 1 Chapter 4 SCF

Hello, in ex 1 ch 4 on SCF the balancing figure on PPE a/c (cash additions) needs to be found to be included in the SCF. The question states the b/f amt (26 574), c/f amt (43 282), depreciation charge for the year (4 658) and disposal amt (1 974). The B/F and C/F amounts taken from the SFP given in the question are already net of accumulated depreciation and I understand that the accumulated depreciation includes already the depreciation charge for the passing year, doesn’t it? If this is the case, why do we deduct the depreciation charge for the year again while working out the missing figure? Isn’t it doubling? Please help me understand. Thank you very much!
