  F(−1)= ⌊ ((−4)/4) ⌋ = −1     F(1) = ⌈ ((8−2)/3) ⌉ = 2   F(2−F(−1)+F(1))= F(2−(−1)+2 )   = F(5) = ⌈ ((8−10)/3) ⌉ = ⌈−(2/3) ⌉ = 0
$$\:\:\mathrm{F}\left(−\mathrm{1}\right)=\:\lfloor\:\frac{−\mathrm{4}}{\mathrm{4}}\:\rfloor\:=\:−\mathrm{1}\: \\ $$$$\:\:\mathrm{F}\left(\mathrm{1}\right)\:=\:\lceil\:\frac{\mathrm{8}−\mathrm{2}}{\mathrm{3}}\:\rceil\:=\:\mathrm{2} \\ $$$$\:\mathrm{F}\left(\mathrm{2}−\mathrm{F}\left(−\mathrm{1}\right)+\mathrm{F}\left(\mathrm{1}\right)\right)=\:\mathrm{F}\left(\mathrm{2}−\left(−\mathrm{1}\right)+\mathrm{2}\:\right) \\ $$$$\:=\:\mathrm{F}\left(\mathrm{5}\right)\:=\:\lceil\:\frac{\mathrm{8}−\mathrm{10}}{\mathrm{3}}\:\rceil\:=\:\lceil−\frac{\mathrm{2}}{\mathrm{3}}\:\rceil\:=\:\mathrm{0}\: \\ $$
