Algebraic numbers are numbers that can be created using arithmetic operations like addition, subtraction, multiplication, and division, and using algebraic equations. These equations contain variables, which can be replaced by numbers to find the value of the algebraic number.

Think of it like baking a cake. You have a recipe that tells you what ingredients to use and how to mix them together. You follow the recipe to make the cake, and the end result is a number, like the number of cakes you have made.

In the same way, you can use an algebraic equation to find an algebraic number. For example, if you have the equation "x + 2 = 6", you can find the value of "x" by subtracting 2 from both sides. This will give you the answer "x = 4", which is an algebraic number because it was found using an algebraic equation.

So, algebraic numbers are numbers that can be found using arithmetic operations and algebraic equations. It's like making a cake, where you use a recipe to find the end result, which is a number.
