=(1+100000000)*100000000/2
=5000000050000000
这种类似的题目有公式可以用
和=(首项+末项)×项数/2
这里的首项就是1,末项和项数都是100000000
用等差数列:
(1+100000000)×100000000/2
=5000000050000000
累死我啊!
可以这样计算:(1+100000000)*100000000/2=5000000050000000
=(1+100000000)*100000000/2
=5000000050000000

1+2+...+999
1+2+3.+173+174=?
1+2+3+4+5.(简算)
2+3+1+100+101
1+2+3+.+99999=
(2+4+6+.+98+100)-(1+3+5+.+97+99)
1+1+1+2+2+2+,+99+99+99-100-100-100
1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20 =
1+(1+2分之一)+(1+2+3)分之一+(1+2+3+4)分之一+...+(1+2+...+2013)分之一
(1+3+5+.+2001+2003+2005)-(2+4+6+.+2000+2002+2004)
1+2=,
(1234+2341+3412+4123)÷(1+2+3+4)
角1+2+3+4+5+6+7为多少
1+2+3+4+……+2012+2013
