Difference between 也都不 and 也不都 Are they same?


我们也都不是学生 - We also all not are students.  
我们也不都是学生  - We also not all are students.
The first sentence means All of us are not students and the second one Not all of us are students (thus some of us may have occupations other than students).

都不是 (all not) is full negation and 不都是 (not all) is partial negation.
