What Do You Know About Intro To Variables? - Quiz

A Variable is a symbol for a number we don't know yet. It is usually a letter like x or y. You should learn about variables by taking this quiz.


Questions and Answers
  • 1. 

    Variables is a topic under?

    • A.

      Equation

    • B.

      Decimals

    • C.

      Algebra

    • D.

      BODMAS

    Correct Answer
    A. Equation
    Explanation
    Variables is a topic under algebra. In algebra, variables are used to represent unknown quantities or values that can change. Equations, on the other hand, are mathematical statements that involve variables and express the equality between two expressions. Therefore, variables are a fundamental concept in algebra and are directly related to equations.

    Equation is a topic under which subject?

    • A.

      Mathematics

    • B.

      Music

    • C.

      Creative Art

    • D.

      Sociology

    Correct Answer
    A. Mathematics
    Explanation
    The correct answer is Mathematics because equations are a fundamental concept in mathematics. Equations are used to represent mathematical relationships and solve problems. They involve variables, constants, and mathematical operations. Equations are used in various branches of mathematics, such as algebra, calculus, and geometry. Therefore, it is clear that equations are a topic under the subject of mathematics.

    A number on its own is called a .....

    • A.

      Coefficient

    • B.

      Constant

    • C.

      Variables

    • D.

      Operator

    Correct Answer
    B. Constant
    Explanation
    A number on its own is called a constant because it is a fixed value that does not change. Unlike variables, which can vary or be assigned different values, constants remain the same throughout a problem or equation. Coefficients, on the other hand, are the numerical factors that multiply variables, and operators are symbols used to perform mathematical operations. Therefore, the correct answer is constant.

    ..... is a number used to multiply a variable

    • A.

      Variable

    • B.

      Constant

    • C.

      Operator

    • D.

      Co-effient

    Correct Answer
    D. Co-effient
    Explanation
    A coefficient is a number used to multiply a variable. In algebraic expressions, variables are often multiplied by coefficients to represent the relationship between the variable and the other terms in the expression. Coefficients can be positive or negative and help determine the scale or magnitude of the variable. They are essential in solving equations and simplifying expressions.

  • 5. 

    An/a ...... is a symbol (such as +, ×, etc) that shows an operation (ie we want to do something with the values).

    • A.

      Operator

    • B.

      Constant

    • C.

      Co-efficient

    • D.

      Variable

    Correct Answer
    A. Operator
    Explanation
    An operator is a symbol that represents an operation to be performed on values. It can be a mathematical symbol like + or ×, or a logical symbol like && or ||. Operators are used to manipulate or combine values in expressions or equations. They indicate the type of operation that needs to be done with the given values.

    Mathematics is usually taught at ....?

    • A.

      Museum

    • B.

      Car park

    • C.

      School

    • D.

      Mosque

    Correct Answer
    C. School
    Explanation
    Mathematics is usually taught at school because it is an essential subject that provides students with the foundational skills and knowledge needed for various academic and real-life applications. Schools have dedicated math teachers, curriculum, and resources to ensure that students receive a comprehensive education in mathematics. Additionally, schools provide a structured learning environment where students can engage in discussions, ask questions, and receive guidance from their teachers, fostering a deeper understanding of mathematical concepts.

    Rate this question:

  • 7. 

    ..... are terms whose variables (and their exponents such as the 2 in x2) are the same.

    • A.

      Equation

    • B.

      Exponent

    • C.

      Like Terms

    • D.

      Constant

    Correct Answer
    C. Like Terms
    Explanation
    Like terms are terms whose variables (and their exponents) are the same. In other words, like terms have the same combination of variables and exponents. For example, 3x^2 and 4x^2 are like terms because they both have the variable x raised to the power of 2. However, 3x^2 and 4x^3 are not like terms because they have different exponents. Like terms can be combined or simplified by adding or subtracting their coefficients while keeping the variables and exponents the same.

    "Variable" comes from a .... word?

    • A.

      Greek

    • B.

      Latin
