不准搬動數字,不准加英文字或數目字,也不准把等號簡單的變成不等號,數學符號則隨便你加多少,要把下面一個未完成的等式成功的完成:
2 2 =9

用微分defferenciation便可以了!
(22)'=(9)'
左右皆於0
嘻嘻,不知這樣算不算是答案呢?

廿二同九既一次方等如零?
唔係等如返廿二同九咩?

唔明"數學符號則隨便你加多少"點解
如果可以加符號,但係又唔加得數目字
咁要咁多符號做乜?

Come on people. 數學符號 is allowed, but not numbers or alphabets. Use some of your good imagination!

What about powers? Are exponents numbers?

Two cube add two to the zero is nine.

2^3 + 2^0 = 9

2.222... = 2 and 2/9 = 20/9
sqrt(9) = 3

對不起﹐我搞糊塗啦﹗
因為答案是在睡覺時想的﹐醒來後弄錯了﹗
應是
2/.2222222..... = 9
(二除�葧`環二等於九)

Silly, you've got it, you figured it out before the record (somebody actually thought for this question for one year!) The answer is:
.
2/.2=9

This way, you don't need to add any thing and you don't need to change the equal sign to make it true. Congratulations, Silly!

the answer that I ment to type is 2 divided by .2 repeating (remember that little dot or the dash?) equals to nine!
