最最经典的解答：（224×222）=【223+1】【223-1】=223^2-1 【对后面的解释】
（224+1/222）*1/223
=224÷223+1/222÷223
=224/223+1/(222×223)
=（224×222）/(222×223)+1/(222×223)
=(223^2-1)/(222×223)+1/(222×223)
=223^2 /(222×223)
=223/222
（224+1/222）*1/223
=224÷223+1/222÷223
=224/223+1/(222×223)
=（224×222）/(222×223)+1/(222×223)
=(223^2-1)/(222×223)+1/(222×223)
=223^2 /(222×223)
=223/222
