Hi,
It's been seven years since I took a math course. I recently bought Manhattan GMAT math books since its been highly recommend by this community. I just opened the first chapter "Number Properties", and started going through the divisible rules and realized I understand the rules but don't know how to apply them.
For example: Rule # 8 if an integer is divisible by 2 THREE times or 8 one time then its an integer, however I don't remember how to divide. One example they give is that 23,456 is divisible by two three times its an integer. I just can't divide 456 by 2 in my head to reach that conclusion. What I'm asking is, is there a good math book that will reteach me how to divide long numbers such as above or shortcuts. I'm looking for something elementary.
Thanks,
