What do you know about solving equations? The process of solving equations of various forms. It also shows you how to check your answer three different ways: algebraically, graphically, and using the concept of equivalence.

Questions and Answers
• 1.

In ...., an equation is a statement of an equality containing one or more variables.

• A.

Literature

• B.

Mathematics

• C.

Biology

• D.

Chemistry

Correct Answer
B. Mathematics
Explanation
In mathematics, an equation is a statement of an equality containing one or more variables. This means that in mathematics, equations are used to represent relationships between variables and to solve for unknown values. Equations are a fundamental concept in mathematics and are used in various branches of the subject, such as algebra, calculus, and geometry.

..... are also called unknowns.

• A.

Variables

• B.

Constants

• C.

Operators

• D.

Coefficients

Correct Answer
A. Variables
Explanation
Variables are entities that can take on different values, hence they are also called unknowns. In mathematical equations, variables represent unknown quantities that need to be determined. They are used to solve equations and express relationships between different quantities. By assigning values to variables, we can find solutions to equations and understand the behavior of mathematical functions. Therefore, variables are commonly referred to as unknowns.

Rate this question:

• 3.

There are how many kinds of equations?

• A.

One

• B.

Two

• C.

Three

• D.

Four

Correct Answer
B. Two
Explanation
The given question asks about the number of kinds of equations. The answer "two" implies that there are only two kinds of equations. This suggests that there are two main types of equations, which could be further explained as linear equations and quadratic equations, or any other specific types of equations that are commonly known.

Rate this question:

• 4.

An equation is written as ....

• A.

One expression

• B.

Three expressions

• C.

Two expressions

• D.

Four expressions

Correct Answer
C. Two expressions
Explanation
An equation is a mathematical statement that shows the equality between two expressions. In order to represent this equality, an equation typically consists of two expressions separated by an equal sign. Therefore, the correct answer is "two expressions" as it accurately describes the structure of an equation.

Rate this question:

• 5.

An equation is written as two expressions, connected by a .....

• A.

Equal sign

• B.

Addition sign

• C.

Multiplication sign

• D.

Subtraction sign

Correct Answer
A. Equal sign
Explanation
An equation is a mathematical statement that shows the equality between two expressions. The equal sign is used to connect these two expressions and indicate that they have the same value.

Rate this question:

• 6.

Algebra studies how many main families of equations?

• A.

Four

• B.

Three

• C.

One

• D.

Two

Correct Answer
D. Two
Explanation
Algebra studies two main families of equations. This implies that algebra focuses on two types of equations, which may include linear equations, quadratic equations, exponential equations, or any other types of equations that fall under these two families.

Rate this question:

• 7.

The "=" symbol, which appears in every equation, was invented in ....

• A.

1557

• B.

1616

• C.

1558

• D.

1996

Correct Answer
A. 1557
Explanation
The correct answer is 1557. The "=" symbol, also known as the equal sign, is a fundamental mathematical symbol used to indicate that two expressions are equal. It was invented by Robert Recorde, a Welsh mathematician, in his book "The Whetstone of Witte" published in 1557. This symbol revolutionized mathematics by providing a concise and efficient way to express mathematical equations and relationships.

Rate this question:

• 8.

The "=" symbol, which appears in every equation, was invented in 1557 by .....

• A.

Albert Eisntein

• B.

Robert Recorde

• C.

Isaac Newton

• D.

Bill Nye

Correct Answer
B. Robert Recorde
Explanation
Robert Recorde is credited with inventing the "=" symbol, also known as the equals sign, in 1557. This symbol is used in every equation to denote equality between two expressions or values. Albert Einstein, Isaac Newton, and Bill Nye are all well-known figures in their respective fields, but they are not associated with the invention of the "=" symbol.

Rate this question:

• 9.

Mathematics is usually studied in ....

• A.

Home

• B.

School

• C.

Museum

• D.

Restaurant

Correct Answer
B. School
Explanation
Mathematics is usually studied in school because it is an essential subject that is included in the curriculum of educational institutions. Schools provide a structured environment where students can learn and practice mathematical concepts and skills under the guidance of qualified teachers. The classroom setting allows for interactive learning, group discussions, and access to resources like textbooks and educational materials. Additionally, schools often have dedicated math teachers who specialize in teaching the subject, ensuring that students receive a comprehensive education in mathematics.

Rate this question:

• 10.

Who is not known as a mathematician here?

• A.

Albert Einstein

• B.

Isaac Newton

• C.

Will Smith

• D.

Pythagoras

Correct Answer
C. Will Smith
Explanation
Will Smith is not known as a mathematician because he is primarily known as an actor and rapper, not for his contributions or expertise in mathematics. On the other hand, Albert Einstein, Isaac Newton, and Pythagoras are all renowned mathematicians who have made significant contributions to the field.
