In algebra, variables and constants are super important!
Variables are like letters, such as or , that stand for unknown numbers. For example, in the expression , the can be any number.
Constants are numbers that always stay the same. In the same expression, is a constant because it never changes.
Knowing the difference between these two is really key to understanding how to create and solve equations.
For example, if we say , we can plug it into the equation like this: .
This way of using variables helps us connect real-life problems to math solutions!
