You are right. Your book is wrong. "not bad" should be written as búcuò. Book also will make some mistakes.

In fact, North Chinese like speaking "哪儿"， and South Chinese use "哪里" more。Their meaning is same, means "where". If you are sure your pronunciation is good, maybe that guy who can't understand is South Chinese

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.

习惯上，我们常说”向...问好“，是一种客套的表达，例如：“请替我向你的爸爸妈妈问好。” 一般不说“向...问候”，这样说：“请替我问候你的家人。” 以上两个例句一个意思，但是我们常用第一个例句。

除...（之、以）外，表示前后两种情况同时存在或两个动作同时发生，而且后一句中常用“也、还“来呼应前一句。

These sentences are not very fluent. I think you need tell us the English sentences of these Chinese.So we can know the exact meaning
