Expressions and Equations Vocabulary

What is the difference between an expression and an equation?

• An expression has an equals sign, while an equation does not.

• An expression is a mathematical phrase, while an equation is a statement of equality.

• An expression can only contain numbers, while an equation can contain variables.

• An expression does not have an equals sign, while an equation does.

What is the distributive property?

• a(b + c) = ab + ac, distributing a number across a sum.

• a(b + c) = a + b + c, adding the numbers together.

• a(b + c) = ab + c, multiplying only the first term.

• a(b + c) = a(b) + a(c), separating the terms.

What are like terms?

• Terms that have different variables.

• Terms that have the same variable raised to the same power.

• Terms that are added together.

• Terms that have no variables.

What is an expression?

• A combination of numbers, variables, and operations without an equals sign.

• A mathematical statement that includes an equals sign.

• A single number or variable without any operations.

• A formula used to calculate the area of a shape.

What is a variable?

• A symbol, usually a letter, that represents an unknown number.

• A fixed value that does not change.

• A type of data structure used to store multiple values.

• A function that performs a specific task.

What is the addition property of equality?

• If you multiply both sides of an equation by the same number, the two sides remain equal.

• If you subtract the same number from both sides of an equation, the two sides remain equal.

• If you add the same number to both sides of an equation, the two sides remain equal.

• If you divide both sides of an equation by the same number, the two sides remain equal.

What is the division property of equality?

• If you divide both sides of an equation by the same non-zero number, the two sides remain equal.

• If you multiply both sides of an equation by the same non-zero number, the two sides remain equal.

• If you add the same number to both sides of an equation, the two sides remain equal.

• If you subtract the same number from both sides of an equation, the two sides remain equal.

What does it mean to simplify?

• Combine like terms

• Add different terms

• Multiply all terms

• Subtract from the total

What is a coefficient?

• The number in front of a variable

• A type of polynomial

• A constant term in an equation

• The sum of two variables

What is a constant?

• A number without a variable

• A variable that changes

• A mathematical operation

• A type of equation
