Trebling and thirding

 my math group and I are working on different strategies in class, yesterday we were working on a strategy called trebling and thirding. This is how it works:

If you had a question like 6X3=?

You would X the 3 by 3, then divide the 6 by 3, which would equal 9X2= ?

which would equal 18!
