Understanding Variables and Constants

The video tutorial explains the concepts of coefficients, constant terms, and variable terms in mathematical expressions. It begins with an introduction to basic terms and coefficients, followed by a detailed explanation of constant terms, which are values that do not change. Examples such as '4', '3 squared', and '6/3' are provided to illustrate constant terms. The tutorial then introduces variable terms, which can change depending on the variable's value, with examples like '8y' and '4y^2'. Finally, the video demonstrates how to identify constant and variable terms within expressions, concluding with a practical example that includes three constant terms and one variable term.

What is a coefficient in an expression?

• A number that is added to a variable

• A number that divides a variable

• A number that multiplies a variable

• A number that is subtracted from a variable

Which of the following is a constant term?

• 5x

• 3 squared

• 2y

Why is 6/3 considered a constant term?

• Because it results in a fixed value

• Because it involves division

• Because it includes a variable

• Because it is a fraction

What makes a term variable?
