Lorraine Said:Can you begin a whole number with zero?We Answered:well im just 13 but it seems to me you are correct. the only whole number that begins with zero is zero itself.

In which case the answer would obviously be 3. Hope I helped! Yeah, i agree with the other people. 0 is just a placeholder. But I still think ur right.Barry Said:I am in 7th grade attending 8th...

## Gmat Math Review

Jose Said:Are these books sufficient for GMAT preparation? Or are the excessive?We Answered:That's a solid list, but I'd substitute some of Kaplan and PR books out for more Manhattan GMAT and Powerscore books--those books are more focused whereas the Kaplan stuff is more generalized and less helpful, I think. I'd add: Math: Manhattan GMAT guides for the different math questions. Short but solid help. OG Quant is good, but it is just problems. A math guide will help explain how to do the problems. Verbal: The Powerscore GMAT Bible that covers the verbal section. Much more comprehensive than others I've...
