I don't know?

Question

Explain how you can solve 40 x 16 by breaking apart the numbers.

Answer 1

    40

 x 16

  -----

  240     <-  this is 6*40

  400     <-  this is 10*40   [note that I added 0 instead of the usual blank]

 ------

  640

Answer 2

Hy Anabel,

 

 

You can break apart the numbers as follows

 

40(10) + 40(6)

 

= 400 + 240

 

= 640

 

 

Hopefully you can understand the way I'm working this problem.
