Answer:
Imagine we are to express  [
a
,
b
]  in set notation
A
=
[
a
,
b
]
, then  A
=
{
x  ∈  R  /  a
≤
x
≤
b
}
In this notation we define the characteristics of all  x  belonging to this set  A
....x must be greater or equal to a and simultaneously smaller or equal to b...
Interval notation is other way to say the same but assuming that  means the extreme a is IN the interval and  means extreme  a  is not.
