\(2006.\left(43.10-2.43.5\right)+10\\ =2006\left(43.10-43.10\right)+10\\ =2006\left(430-430\right)+10\\ =2006.0+10\\ =10\)

Answer 2

[꧁_͏ͥ͏_͏ͣ͏_͏ͫ͏ ¡亗ᵛᶰシ๖ۣۜT๖ۣۜR๖ۣۜÂ๖ۣ...]

\(2006\times\left(43\times10-2\times43\times5\right)+10\) 

\(=2006\times\left(43\times10-43\times10\right)+10\) 

\(=2006\times0+10\) 

\(=0+10\) 

\(=10\)
