Assistance needed.

Please type your __subject__ in the **School Subject** box. Any other words are likely to delay responses from a teacher who knows that subject well.

I searched Google under the key words "*compatible numbers math*" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.

Are you sure that is 3rd grade? I am a 4th grader and I don't know any thing about it.

ps. When you are done with homework go to clubpegiun. It is really cool.
