I am little confused about the following statements.
Its obvious that they are not logically equivalent. But lets take some examples.
let P(x) = x is majoring in maths
M(x)= x is mad.
so the statement 2 means that all math majors are mad and
statement 1 means that if there is a math major then he is mad
no, statement 1 means there is at least one math major who is mad
here it looks like they are equivalent in meaning. so whats happening ?
