inverse operation

• upside down

• The operation that undoes what was done by the previous operation.

properties of equality

• There are 10 properties.

• They are the equal ways to divide and subtract in algebraic equations.

• We have mainly nine properties of equality - addition, subtraction, multiplication, division, reflexive, symmetric, transitive, substitution, and square root properties. The addition, subtraction, multiplication, and division properties of equality help to solve algebraic equations involving real numbers.

• We have three properties of equality.

distributive property

• a property that deals with subtracting numbers.

• a property that deals with percentages.

• a property that says numbers can be added but never broken down into smaller numbers.

• A property that says numbers can be broken down into smaller numbers for calculating.

inequality

• a mathematical statement that says every quantity is equal.

• a mathematical statement that says 4 quantities are not equal.

• A mathematical statement that says two quantities are not equal.

variable

• a number

• is a relationship with at least 10 sets in math.

• Is a relationship between two sets in math.

• a family member

function

• a type of algebraic equation

• an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)

• an expression that does not define a relationship.

• an expression, rule, or law that does not define a relationship between one variable and another.

function notation

• It is a type of geometry problem.

• The notation f(x) defines a function named f. This is read as “y is a function of x.” It is a way to write the equation.

• It is a type of food.

• The notation f(x) does not define a function named f. This is only read as f is not a function of x.
