What is a constant in an expression?

Back

A constant is a fixed value that does not change. In the expression 14 - 8x - 7y - 5, the constants are 14 and -5.

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. In the expression 5q + 3 - 11r, there are no like terms.

How do you identify the number of terms in an expression?

Back

Count each distinct part of the expression separated by + or - signs. For example, in 2y + 3x + 4, there are 3 terms.

How do you combine like terms?

Back

To combine like terms, add or subtract their coefficients while keeping the variable part the same. For example, 3x + 2x = 5x.

What is the degree of a term?

Back

The degree of a term is the exponent of the variable in that term. For example, in 4x^2, the degree is 2.
