We have measured the normal state magnetoresistance (-Δσ; B ⊥ I ⊥ c, - Δσ; B∥I ⊥ c) of a Bi2.1Sr1.9Ca1.0Cu2O 8+δ single crystal. At low temperatures (ε≡(T - Tc)/Tc ≤, 0.1), the orbital magnetoresistance (-Δσ + Δδ) can be well fitted by the 2D limit of the Aslamazov-Larkin (AL) fluctuation (-ΔALO α ε-3). At high temperatures (ε > 0.1), it can be fitted either by the contribution of the Maki-Thompson (MT) fluctuation or by the anomalous normal state magnetoresistance. We have also measured the resistivities of these crystals up to 870 K and found that in this slightly overdoped region the scattering rate can be expressed as a sum of the typical T-linear and the T2 components. The T2 component can be assigned to electron-electron scattering originating from the Fermi liquid.
