Understanding Variable and Constant Terms

The video tutorial explains the concept of constants in mathematics. A constant is defined as a fixed value that does not change. The tutorial uses the expression 5x + 2 to illustrate the difference between variable and constant terms. It shows how the term 5x changes with different values of x, while the term 2 remains constant regardless of the value of x. This demonstrates that a constant is a value that remains unchanged.

What is a constant in mathematical terms?

• A fixed value that does not change

• A term that varies with time

• A value that changes with variables

• A variable that can be adjusted
