What is a coefficient?

• A letter in an equation

• A number multiplied by a variable in an algebraic expression.

• An operation in math

• A solution

What is an inequality?

• two expressions on either side of an inequality symbol

• a single number, variable, or the product of numbers and variables

• A situation with only one solution

• a number line

What is an equation?

• a combination of individual terms separated by plus or minus signs, including variables

• A mathematical sentence that has one expression with no equal sign.

• A mathematical sentence in which two expressions appear on either side of an “equals” sign (=), stating that the two expressions are equivalent.

• Any operation in mathematics

What does it mean to evaluate?

• To perform multiple operations

• To simplify an expression

• To find the numerical value of.; substitute the value(s) given for the variable(s) and perform the operations according to the Order of Operations.

• order of operations

What is a boundary point?

• A solution to an equation.

• The endpoint or endpoints of a ray or segment on a number line where an inequality is true.

• To substitute a number into an expression to make the equation true.

• A bunch of numbers that represent the solution.

What is a solution?

• The number or numbers that when substituted into an equation or inequality make the equation or inequality true.

• A number on the number line that represents the end point.

• two expressions on either side of an inequality symbol

• A number multiplied by a variable in an algebraic expression.

What are inequality symbols?

• Various operations symbols that can be used in the order of operations

• Parenthesis

• An operation symbol used in order of operations

• The symbol ≤ read from left to right means “less than or equal to,” the symbol ≥ read from left to right means “greater than or equal to,” and the symbols < and > mean “less than” and “greater than,”

What does it mean to simplify?

• The number or numbers that when substituted into an equation or inequality make the equation or inequality true.

• write a less complicated expression with the same value. It has no parentheses and no like terms.

• a single number, variable, or the product of numbers and variables

• Find the answer

What is the distributive property?

• a(b + c) = ac + ac; when a quantity is represented multiple times

• When you change the order of the problem and still get the same answer.

• When you add a number to zero and get the same result.

• When you rewrite the problem in a different order.

What is an algebraic expression?

• A combination of numbers and operation symbols.

• when you use the order of operations to simplify

• a combination of individual terms separated by plus or minus signs, including variables

• either side of an “equals” sign (=), stating that the two expressions are equivalent.
