What is another name for the counting numbers 1, 2, 3, 4, 5, and so on?

  1. Natural numbers
  2. Whole numbers
  3. Prime numbers
  4. Even numbers
Show answer and solution

Correct answer: A. Natural numbers

1. The numbers 1, 2, 3, 4, 5, and so on are the counting numbers. 2. These same numbers are also known by another name in mathematics. 3. Counting numbers are also called natural numbers. 4. Whole numbers add zero to this list, so that name describes a different set, and prime and even numbers are only special subsets of it. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 1 "Whole Numbers", section 1.1 Introduction to Whole Numbers_

Which set of numbers is formed by including zero together with the counting numbers?

  1. The natural numbers
  2. The whole numbers
  3. The negative numbers
  4. The prime numbers
Show answer and solution

Correct answer: B. The whole numbers

1. The counting numbers are 1, 2, 3, 4, 5, and so on. 2. Adding the number zero to this list creates a new set of numbers. 3. The whole numbers are the counting numbers and zero. 4. Natural numbers is another name for the counting numbers without zero, and negative and prime numbers describe different sets entirely. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 1 "Whole Numbers", section 1.1 Introduction to Whole Numbers_

On a number line, what is the point labeled 0 called?

  1. The coordinate
  2. The denominator
  3. The origin
  4. The remainder
Show answer and solution

Correct answer: C. The origin

1. A number line has equally spaced points labeled with numbers. 2. The starting point of the number line is labeled 0. 3. The point labeled 0 is called the origin. 4. The coordinate is the number paired with a point, the denominator belongs to fractions, and the remainder belongs to division, so none of those name the point 0. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 1 "Whole Numbers", section 1.1 Introduction to Whole Numbers_
