合并同类项：a-2a-3a+4a+5a-6a-7a+8a+9a-10a-11a+12a+……+2008a+2009a-2010a-2011a
a-2a+3a-4a+5a-6a+7a-8a+9a-10a+11a.+99a-100a=
(3a+5)-{9a-[6a+2-(12a-10)+2(a+1)]}
（3a+5)-{9a-[6a+2-(12a-10)+2(a+1)]
a-2a-3a+4a+5a-6a-7a+8a+9a-10a-11a.+2008a+2009a-2010a-2011a如何合并同类项?
逻辑运算中A表示什么 (1) 0 · A = 0 (10) 1' = 0; 0' = 1 (2) 1 · A = A (11) 1 + A = 1 (3) A · A = A (12) 0 + A = A (4) A · A' = 0 (13) A + A = A (5) A · B = B · A (14) A + A' = 1 (6) A·(B·C) = (A·B)·C (15) A
计算;(a^3)^4+a^10×a^2-a×a^2-a*a^3*a^8
(12a^5 - 6a - 10a^3) - (10a - 2a^5 - 14a^4) 是等于 14a^10 - 16a - 10a^3 + 14a^4
a-2a+3a-4a+5a-6a+...+99a-100a
化简; a-2a+3a-4a+5a-6a+``````-2006a+2007a.
(a+3a+5a+...+2009a)-(2a+4a+6a+...+2008a)=
(a+3a+5a+.+2009a)-(2a+4a+6a+.2008a)
计算（a+3a+5a+...+2009a)-(2a+4a+6a+...+2010a)
(a+3a+5a+...+2013a)-(2a+4a+6a+...+2012a)=
化简：a-2a+3a-4a+5a-6a+.+2010a+2011a.
计算(a+3a+5a+.+2003a)-(2a+4a+6a+...+2004a)
(a+3a+5a+.+2003a)-(2a+4a+6a+.+2004a)
（a+3a+5a...+2009a)-(2a+4a+6a+...+2010a)=?
