22 is 二十二，222 is 两百二十二or 二百二十二，2222 is 两千两百二十二or两千二百二十二。 the last three are correct ! 两can be only used before 十 when you try to say a number which is bigger than 20 .And 两 和 二can be used before 百. Both is OK! Another point is that 两个 is correct and 二个 is wrong! for example ,两本书，两个人，两张纸.......we can't use 二 here .I think we do this to speak more fluently!

before千、万、亿use “两”，before百、十use“二”

number “ 1 ”: If you read it in telephone number, room number or identify card number, “ 1 ” usually read “ yāo ”. number “ 2 ”: 　　A: If you read it in number 2, 20, or number 2 appears at last, for example, 12,22,32...,102,112,120..., read it “ èr ”. 　　B: In numbers more than 200, 2000, 20000 and so on, if “2 ” isn’t the last number or the last second number, it usually read “ liǎng ”. Number 200, “ èr bǎi ” and “ liǎng bǎi ”, both are OK. For example:2222, read it “liǎng qiān liǎng běi èr shí èr” or “liǎng qian èr bǎi èr shí èr”. Notes: 250, can read “èr bǎi wǔ”, “èr bǎi wǔ shí”, “liǎng bǎi wǔ”, “liǎng bǎi wǔ shí”. But in chinese, the “250” has a special meaning. For example, if we say somebody is “èr bǎi wǔ”, it means this person is not too good. So most of time when we need say “250”, we say the other three.

無論2 置於 個 十 百 千 萬 億 兆 京位 一概讀作 二 沒人敢說你是錯的 22 二十二 222 二百二十二 2222 二千二百二十二 1210 一千二百一十 2862 二千八百六十二 8226 八千二百二十六 在台灣小學的數學課裡 讀二作兩 反而是錯誤的 兩 字的原始意義 並不作數字用法 而是指 天生自然成雙成對的人 事 物 如 哲學觀念 : 太極生兩儀 兩儀生四象 物體 : 兩邊 兩面 兩端 兩極 人體 : 兩腿 兩眼 兩手 事 : 兩姓合婚 (天生自然 故能合婚) 兩小無猜 (自然在一起的)
