    • A.

      Co-efficient

    • B.

      Constant

    • C.

      Substitutions

    • D.

      Operator

    Correct Answer
    C. Substitutions
    Explanation
    Substitutions means replacing the letters in an equation or expression with specific numbers. In mathematics, when solving equations or evaluating expressions, we often use substitutions to simplify the problem by assigning values to the variables. By substituting numbers for letters, we can then perform calculations and find the solution. Therefore, "substitutions" is the correct answer as it accurately describes the process of putting numbers where the letters are in mathematical equations or expressions.

    • D.

      Decimals

    Correct Answer
    A. Evaluating expressions
    Explanation
    When we substitute a specific value for each variable in an expression and then perform the operations, it is called evaluating expressions. This process allows us to determine the value of the expression for the given values of the variables. It is a fundamental concept in mathematics and is used in various applications such as solving equations, simplifying expressions, and finding the value of a function at a specific point.

    • C.

      Symbols

    • D.

      None

    Correct Answer
    B. Letter
    Explanation
    In Algebra, we don't use blank boxes to represent unknown values or variables. Instead, we use letters to represent these variables. This allows us to generalize equations and solve for unknown quantities in a more flexible and efficient manner. By using letters, we can easily manipulate and solve equations involving multiple variables, making Algebra a powerful tool in mathematics.
