數學題目(S1)

n!=1*2*3*4*5..............*n

--->1*2*3*4*5*6*7*8*9.........*2009*2010=2010! (which is much more than answer of 001 & 002) no one will lose time to find the actual answer as I know

You should know that 1*2*3*4*5*6*7*8*9................*20 is already over the answer which 001 is given, so their answer most likely are wrong.

001 的答案用錯算式,假若題目是1+2+3+4+5+6+7+8+9.........+2009+2010的話,他是對的,他是用了 (項首+項尾)*項數 的原理。
可是題目是乘數而非加數,故此理不可應用~

002簡直是自打嘴巴。既然對001說出答案不會這樣小,他的數卻比他更小


P.S.:I can only think of this equation to solve the question but I am not so sure do you know this equation since I just remember this equation was learn during secondary education

Sorry ! 我承認因我的疏忽 (看不到那 “!” ) 而對002作出了不公平的指控,故藉此對其及各位致歉。亦感謝Yogi的提點,容我在此說聲謝。

2021055
因為1+2010=2011
2+2009=2011
3+2008=2011....
咁即係會冇左一半啦全部既話
(1+2010)=冇左2個
咁即係將2010除以2=1005
咁將1005*2011既話
咁就係2021055啦;)
希望幫到你啦

To 003: 2010! 竟然比 2021055 細？？

「002簡直是自打嘴巴。既然對001說出答案不會這樣小,他的數卻比他更小」

The answer is 2010!

To 001,個數點會甘小..........

To 003,如果你不懂的話,就請不要回答.....

!在數學上是有意思的!
