About This Quiz

In the field of mathematics, directed numbers are numbers which have a direction (either positive or negative) and a size (either whole number or decimal number). In addition, they can be added and subtracted together just like standard positive integers. However, signs are very important as each directed number individually has its own direction.

    What is a whole directed number called?  - ProProfs

    What is a whole directed number called? 

    • Sparrow

    • Integer

    • Value

    • Momentum

    Correct Answer
    A. Integer
    Explanation
    A whole directed number is called an integer. Integers are numbers that include both positive and negative whole numbers, as well as zero. They are used to represent quantities that can be counted or measured in both forward and backward directions. Integers are commonly used in mathematics and are an essential concept in number theory and algebra.

    What is a number without a sign? - ProProfs

    What is a number without a sign?

    • Positive

    • Unequal

    • Negative 

    • Directionless

    Correct Answer
    A. Positive
    Explanation
    A number without a sign refers to a positive number. In mathematics, positive numbers are represented without a sign symbol, indicating that they are greater than zero. Unlike negative numbers which have a minus sign (-), positive numbers are considered to be directionless and do not indicate any specific direction. Therefore, the correct answer is positive.

    What do directed numbers have?  - ProProfs

    What do directed numbers have? 

    • Direction

    • Bracket

    • Inequality

    • Momentum

    Correct Answer
    A. Direction
    Explanation
    Directed numbers have direction. This means that they can be positive or negative, indicating whether they are greater or lesser than zero. The sign of a directed number represents its direction, with positive numbers indicating a forward or upward direction, and negative numbers indicating a backward or downward direction. The concept of direction is fundamental in understanding and working with directed numbers.

    What are directed numbers? - ProProfs

    What are directed numbers?

    • Equal

    • Positive

    • Negative

    • Positive or negative

    Correct Answer
    A. Positive or negative
    Explanation
    Directed numbers, also known as signed numbers, are numbers that can be either positive or negative. They are used to represent quantities that have both magnitude and direction. Positive directed numbers represent quantities that are greater than zero, while negative directed numbers represent quantities that are less than zero. The answer "Positive or negative" accurately describes directed numbers as they can be either positive or negative depending on the context.

    Which question does a cardinal number answer? - ProProfs

    Which question does a cardinal number answer?

    • When

    • Where

    • How many

    • How weighted

    Correct Answer
    A. How many
    Explanation
    A cardinal number is a number used to indicate quantity or how many of something there is. Therefore, the question that a cardinal number answers is "How many?" This question seeks to determine the quantity or number of something.

    What do ordinal numbers deal with? - ProProfs

    What do ordinal numbers deal with?

    • Importance

    • Value

    • Position

    • Direction

    Correct Answer
    A. Position
    Explanation
    Ordinal numbers deal with the position or order of things in a sequence or series. They are used to indicate the position of an element in relation to others, such as first, second, third, etc. Ordinal numbers are different from cardinal numbers, which represent quantity or value. Therefore, the correct answer is "Position."

    Which one of these do directed numbers have? - ProProfs

    Which one of these do directed numbers have?

    • Size

    • Bracket

    • Inequality

    • Trig

    Correct Answer
    A. Size
    Explanation
    Directed numbers have a concept of size or magnitude. This refers to the numerical value of the number, regardless of its sign. For example, both -5 and 5 have a size of 5. Size helps us compare and order numbers, understanding their relative values.

    Which term tells how far a number is from zero?  - ProProfs

    Which term tells how far a number is from zero? 

    • Absolute value

    • Real Value

    • Directed number

    • Directed Value

    Correct Answer
    A. Absolute value
    Explanation
    The term "absolute value" refers to the distance of a number from zero on a number line. It is always a positive value, as it represents the magnitude or size of the number, regardless of its sign. Therefore, the absolute value is the correct term that tells how far a number is from zero.

    What is a nominal number used for? - ProProfs

    What is a nominal number used for?

    • Value

    • Cardination

    • Position

    • Identification

    Correct Answer
    A. Identification
    Explanation
    A nominal number is used for identification purposes. It is a type of number that is assigned to something or someone in order to uniquely identify them. This can be seen in various contexts such as identification numbers for individuals, product codes for items, or account numbers for customers. The purpose of a nominal number is to provide a distinct identifier that can be used to differentiate and track different entities.
