Compute 12*143+6*214.

 

Well, I know how to do it using a calculator, but I wanted to know how one could do it without dully doing the multiplying out... I know the answer, it's 3000, but I really want to know if there is a side-way.

 

Thank you.

Do you mean something like:

 

12*143+6*214 = 6*2*143 + 6*214   

 

6*2*143 + 6*214  = 6*(2*143 + 214)

 

6*(2*143 + 214) = 6*(286 + 214)

 

6*(286 + 214) = 6* 500  = 3000
