Beijing - Numbers constitute an important part of Premier Wen Jiabao's government work report, but not because the Chinese are known for their math skills.

The largest figure is 55 trillion yuan ($8.4 trillion), the projected total GDP in 2015 (based on 2010 prices), or about $6,000 if calculated per capita.

But there are also small figures. One is Wen's pledge: "We will ensure that primary and middle school students do one hour of physical exercise in school every day."
