化简2m*2m-4(m-2)(2m-3)

已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| (m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m) (m+3m+5m+...+2009m)-(2m+4m+6m+...2008m) m-2m-3m+4m-5m-6m+7m.2004m=? 计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m) (m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m) (m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=? (m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m) (m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)= 化简(m*m-2m)/(4-m*m) m+3m+5m+...+2011m-2m-4m-...-2010m等于多少? (m+3m+5m+...+2009m)-(2m+4m+...+2008m)怎么算
