I am from Vietnam and have just transferred to Australia. And I have a lot of trouble with understanding the way people use "verbal expressions on mathematics operations (addition, subtraction,...). I am in advanced math; it's not a problem with doing math but a problem with vocabulary.
It's familiar when they say :"1 plus 1 equals 2" to express 1+1=2. But then sometimes I heard they said :"1 increased by 1 equals 2". Or when they use the phrase "one subtracted by one is zero", "subtracted from" instead of "minus". It's just that I hardly fully understand what my teacher say and I am very afraid to misunderstand or miss something in the future. Furthermore, I have been looking in the dictionary and some words that is not even has the structure as what my teacher write such as "4 subtracted by 2 equals 2"
Could anyone recommend a Internet source or a book on this topic (with examples of using the words) ?
