on this website they call these Math Word Problems

This is a Math Word Problem from 3rd Grade section of www.EdHelper.com

Problem:
            CLEAN
          +  SNAP
            COVER

         
(Use the numbers: 5, 7, 4, 6, 0, 3, 8, 9, 1, and 2)

Answer:
             85426
            + 3621
             89047

I'm not sure the best way to do this, let alone teach it.
Can anyone help me out?

Thanks & Blessings, MaBee

Re: on this website they call these Math Word Problems

Hi MamaBee;

Sometimes I use a computer to solve them but mostly a lot of trial and error. There are some hints from the problem:

1) S + L must be less than 10 because there is no carry in the next coulumn.

2) If P + N is less than 10 then E must be even.

3) C is not a 0 because they rarely if ever use a leading digit of 0

4) Neither P or N is a 0 because N + P = N or N + P = P

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
