问题：
Paragraph 3 of IAS 21 notes that its two areas of application are :
translating the results and financial position of foreign operations that are included in the financial statements of the entity  by consolidation or the equity method.
红色句子的俩个方法不太明白，谁懂的话帮忙简单说一下或者给我点链接。
consolidation方法和equity方法是什么？
translating an entity's results and financial position into a presentation currency.
note that there are two different translation processes here. In order to understand this, it is necessary to distinguish between three different type of currency: local currencyl, functional currency and presentation currency. Not all foreign subsidiaries experience all three currencies.
local currency
functional currency
presentation currency
蓝色句子的2个不同翻译过程不知道.
