45x56 is between 40x50 and 50x60, so 2000 and 3000, and should be just a hair higher than 2500. Skip solving, estimate.

2x1=1; 9x1=9 but that is not why we teach it. Say 1/2 x 1 = 2/4 write 1/2 x 2/2 = 2/4
We so often teach concepts without showing how they are applied. I showed this to an auditorium full of math teachers and silenced the room because none had ever made this connection.
