If x is any real number, then [x] means the integral part of x, i.e. x rounded down to the nearest whole number. ( I have never seen the term integer value before.) So for instance [π]=3,√2=1,[42]=42 etc. For completeness: if x is negative, then “rounded down” means “rounded towards −∞”, so e.g. [−2.5]=−3.
What does X stand for in maths?
The letter “x” is often used in algebra to mean a value that is not yet known. It is called a “variable” or sometimes an “unknown”. In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn’t have to be “x”, it could be “y”, “w” or any letter, name or symbol.

Is the phrase ” for each real number x ” a statement?
The phrase “For each real number x” is said to quantify the variable that follows it in the sense that the sentence is claiming that something is true for all real numbers. So this sentence is a statement (which happens to be false).
Is the statement For every x, p ( x ) false?
There exists an integer x such that 3x − 2 = 0. (∃x ∈ Z)(3x − 2 = 0). This statement is false because there are no integers that are solutions of the linear equation 3x − 2 = 0. Table 2.4 summarizes the facts about the two types of quantifiers. “For every x, P(x) ,” where P(x) is a predicate.

(ix) The set of all letters in the word ‘Better.’ So, when we read whole sentence it becomes x is such that x is a letter before ‘e’ in the English alphabet. Now letters before ‘e’ are a,b,c,d. ∴ Roster form will be {a,b,c,d}. x ∈ N that implies x is a natural number. As x belongs to the natural number that means x < 5.
