1.
In mathematics, an equation is a statement of an equality containing one or more .....
Correct Answer
A. Variables
Explanation
An equation in mathematics is a statement that shows the equality between two expressions. The expressions can contain unknown values, which are represented by variables. These variables can take on different values, making the equation true for some values and false for others. Therefore, the correct answer is "variables" because equations involve the use of unknown values that are represented by variables.
2.
There are how many kinds of equations?
Correct Answer
B. Two
Explanation
The question asks about the number of kinds of equations. The answer given is "two." This implies that there are two distinct types or categories of equations. However, without further context or clarification, it is not possible to determine what these two types of equations are.
3.
Each side of an equation will contain ..... terms?
Correct Answer
B. One or more
Explanation
The statement "Each side of an equation will contain one or more terms" implies that an equation can have multiple terms on either side. This means that there can be one term on each side, or there can be multiple terms on each side of the equation. Therefore, the correct answer is "one or more."
4.
The equations has how many sides?
Correct Answer
C. Two
Explanation
The question is asking about the number of sides in the equation. An equation typically consists of two sides, with an equal sign in between. Therefore, the correct answer is two.
5.
Algebra studies how many main families of equations?
Correct Answer
B. Two
Explanation
Algebra studies two main families of equations. Algebra is a branch of mathematics that deals with symbols and the rules for manipulating those symbols. It focuses on solving equations, which are mathematical statements that contain an equals sign. The two main families of equations studied in algebra are linear equations and quadratic equations. Linear equations have variables raised to the power of one, while quadratic equations have variables raised to the power of two. By understanding and solving these two types of equations, algebra allows us to solve a wide range of mathematical problems.
6.
Algebra is a topic under which course or subject?
Correct Answer
C. Maths
Explanation
Algebra is a topic that falls under the subject of Maths. It is a branch of mathematics that deals with symbols and the rules for manipulating those symbols to solve equations and understand mathematical relationships. Algebra is an essential part of the mathematics curriculum and is used in various fields such as physics, engineering, economics, and computer science.
7.
Mathematics is usually studied in ....
Correct Answer
B. School
Explanation
Mathematics is usually studied in school because it is a subject that requires a structured and organized learning environment. Schools provide the necessary resources such as textbooks, teachers, and classrooms to facilitate the study of mathematics. Additionally, schools offer a curriculum that is specifically designed to teach mathematics at various levels, allowing students to progress and build upon their mathematical knowledge and skills. Therefore, school is the most appropriate and common place for studying mathematics.
8.
The sign "–" stands for ....
Correct Answer
B. Subtraction
Explanation
The sign "–" is commonly known as the subtraction symbol. It is used to indicate the operation of subtracting one quantity from another. When this symbol is placed between two numbers, it signifies that the second number should be subtracted from the first number to find the difference between them. This is in contrast to the other mathematical operations such as addition, multiplication, and division, which have their own respective symbols.
9.
The symbol "+" represents ....
Correct Answer
B. Addition
Explanation
The symbol "+" represents addition in mathematics. It is used to combine two or more numbers to find their total or sum. For example, in the equation 2 + 3, the "+" symbol is used to add the numbers 2 and 3 together, resulting in a sum of 5.
10.
Variables are also called .....
Correct Answer
B. Unknowns
Explanation
The correct answer is "unknowns" because variables in mathematics and computer programming are used to represent unknown values or quantities. They are placeholders that can take on different values, which are usually determined through equations or algorithms. Therefore, "unknowns" is the appropriate term to describe variables.
