Example Question #50 : Number Theory
can correctly be considered all of the following types of number, EXCEPT:
Rational
Negative
Real
Integer
Natural
Natural
Negative numbers are integers, they are real, and they are rational. Natural numbers, by definition, are whole and non-negative numbers. Therefore, is NOT a natural number.
Example Question #51 : Number Theory
Which if the following is not an integer?
None of the other answers.
None of the other answers.
Integers comprise negative numbers as well as positive numbers. Even zero is an integer. The caveat of integers is that they must be able to be expressed without fractions. They have to be whole. While is a fraction, it is equivalent to 1, which is a whole number.
Example Question #52 : Number Theory
Which of the following is an integer?
The correct answer will yield a whole number as a simplified answer. Integers cannot contain decimals quantities.
The only answer that will yield a whole number term is since simplifying this root will yield .
The correct answer is:
Example Question #53 : Number Theory
Simplify, if possible:
The expression is already simplified
Combine like-terms.
The square roots cannot be combined unless they are multiplied, which means they must be separate terms.
The answer is:
Example Question #54 : Number Theory
Which of the following is NOT an integer?
An integer is a whole number, or a number that is not a fraction.
Therefore, since is a fraction, it is NOT an integer.
Example Question #55 : Number Theory
Which of the following is NOT a natural number?
Natural numbers are numbers are referred to as counting numbers or positive integers. When we count objects, we do not include the number zero. Therefore, the number zero is NOT a natural number.
Example Question #56 : Number Theory
Which of the following is an integer?
Which of the following is an integer?
An integer is any positive or negative whole number including zero.
So, the only integer provided must be "4," because no other option fits the definition.
Example Question #57 : Number Theory
Which set of numbers is considered to be whole numbers? Choose the best answer.
