MX Setup

[apbios]

I've been trying to setup my MX for the email for a few days now and hasn't worked. I purchased a domain from godaddy.com for my domain biology.x10hosting.com, now biologysap.com and tried to setup and email account with @biologysap.com. To do this, i needed to setup the MX record in the cpanel at X10. Here is what they gave me:

MX 0 - smtp.secureserver.net
MX 10 - mailstore1.secureserver.net

at http://help.godaddy.com/article.php?article_id=321

So I went into my cpane > MX ENTRYl and changed:

biology.x10hosting.com -> 0 smtp.secureserver.net
biologysap.com -> 0 mailstore1.secureserver.net

I don't know what "MX 0" and "MX 10" is. It's already been more than 24 hours. Can someone help me out? Thanks.
