How Well Do You Know One-step Multiplication And Division Equations?

Explanation
An equation is a statement of an equality, meaning that the expression on one side of the equation is equal to the expression on the other side. In order to represent different unknowns or quantities, variables are used in equations. Variables can take on different values and allow for solving equations and finding the values of the unknowns. Ratios, decimals, and proportions are not directly related to the definition of an equation, so they are not the correct answer.

Explanation
Variables are also called "unknowns" because they represent values that are not yet known or determined. In mathematics and programming, variables are used to store and manipulate data, but their specific values may vary depending on the context or the input provided. Therefore, variables can be considered as "unknowns" until they are assigned a specific value or calculated through an equation or algorithm.

Explanation
Variables are unknowns because their values are not initially known. When we solve an equation, we are finding the values of these unknowns that make the equation true. Therefore, the values of the unknowns that satisfy the equality are called the solution of the equation.

Explanation
The question asks about the number of kinds of equations. The correct answer is "two". This implies that there are two different types of equations. However, without further context or information, it is not possible to determine what these two types of equations are.

Explanation
An equation can have one or two terms on each side. This is because an equation is a mathematical statement that shows the equality between two expressions, and each expression can consist of one or multiple terms. Therefore, it is possible for both sides of the equation to have either one or two terms, depending on the specific equation being considered.

Explanation
The equation has two sides because an equation is made up of two expressions separated by an equal sign. Each side of the equation represents a different value or expression, and they are connected by the equal sign to show that they are equal to each other. Therefore, the equation has two sides.

Explanation
Algebra studies two main families of equations. This means that algebra focuses on two distinct categories of equations, which may have different properties, rules, and methods of solving. By studying these two families, algebra provides a foundation for understanding and solving a wide range of mathematical problems and equations.

Explanation
The sign "×" represents multiplication. It is commonly used to indicate the operation of multiplying two or more numbers together to find their product.

Explanation
The symbol "÷" is commonly used to represent the mathematical operation of division. It indicates the process of dividing one number by another to find the quotient or the number of times one quantity is contained in another.

Explanation
Sean Combs is not a scientist. The other three options, Albert Einstein, Isaac Newton, and Bill Nye, are all well-known scientists in their respective fields. Sean Combs, also known as P. Diddy or Diddy, is a rapper, songwriter, and entrepreneur, but not a scientist.
