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.

Substitution is a topic under ....?
- Decimals
- Algebra
- Equations
- BODMAS
Correct Answer

A. Algebra

Explanation

Substitution is a topic under algebra. In algebra, substitution refers to the process of replacing variables with specific values in an equation or expression. This technique is commonly used to solve equations, simplify expressions, or evaluate functions. By substituting specific values for variables, algebraic problems can be simplified and solved more easily.

Means putting numbers where the letters are
- Co-efficient
- Constant
- Substitutions
- Operator
Correct Answer

A. 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.

In Algebra we don't use blank boxes, we use a .....
- Number
- Letter
- Symbols
- None
Correct Answer

A. 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.
