What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 8x - 4, the constant is -4.

Front

What do we call the combination of a base and an exponent?

Back

This combination is called a power. For example, in 4^3, 4 is the base and 3 is the exponent, making 4^3 a power.

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol that represents an unknown value. For example, in the expression 4m - 9, 'm' is the variable.

Front

What is the base in an exponential expression?

Back

The base is the number that is multiplied by itself. For example, in 4^3, the base is 4.

Front

What is an algebraic expression?

Back

An algebraic expression is a mathematical phrase that can include numbers, variables, and operations. For example, 3x + 2 is an algebraic expression.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to make it easier to understand or work with by combining like terms or reducing fractions.

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms.

Front

What is the difference between an equation and an expression?

Back

An equation states that two expressions are equal, while an expression is a combination of numbers and variables without an equality sign.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by each term in a parenthesis.

Front

What is a coefficient?

Back

A coefficient is a number that is multiplied by a variable. For example, in 5x, 5 is the coefficient.
