Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression x - 53, -53 is a constant.

Front

What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both. For example, -4x is a term.

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol used to represent an unknown value. In the expression x - 53 - 4x - w + 6x + 8, x and w are variables.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in -4x, -4 is the coefficient.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of terms that have the same variable. For example, in -5n - 8n, combine to get -13n.

Front

What does 'four less than the product of b and three' mean in algebraic terms?

Back

It means to take the product of b and 3, then subtract 4, which is represented as 3b - 4.

Front

What are the variables in the expression x - 53 - 4x - w + 6x + 8?

Back

The variables are x and w.

Front

What is the result of combining the like terms in the expression -5n + 1 - 8n - 6?

Back

The result is -13n - 5.

Front

What is the difference between a term and a coefficient?

Back

A term is a complete part of an expression (like -4x), while a coefficient is the number in front of a variable in a term (like -4 in -4x).

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to combine like terms and reduce it to its simplest form.
