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
Oh, thank you so much!
