Front

Define 'expression' in mathematics.

Back

An expression is a combination of numbers, variables, and operators (such as + and -) that represents a value.

Front

What does it mean to 'subtract expressions'?

Back

Subtracting expressions involves finding the difference between two algebraic expressions by combining like terms.

Front

What are 'like terms'?

Back

Like terms are terms that have the same variable raised to the same power.

Front

Explain the distributive property.

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is the first step in subtracting expressions?

Back

The first step is to distribute the negative sign across the second expression if necessary.
