Caveman Chang ADDRESSES The Elephant of Algebra (VARIABLES)

Variables are nothing more than imaginary containers. The letters and symbols we use as variables are nothing more than labels for these imaginary containers.

Variable have 2 main usages. The first one is that it represents one specific number. The second one is that it represents some group of numbers.

There are 3 common mistakes when using variables.
1.) People try to multiply different variables. We cannot combine the different variables because we cannot guarantee the value of one variable is the same as that of the other variable.
2.) If we see the same variable in another problem, do not assume the same answer because we already solved for that variable. Unless otherwise stated, we should always solve for the variable all over again in each new problem.
3.) People may use letters and symbols as their variable that already represent something (e.g. pi, e, and i)

Practice Problems:
Level 1: Answer is x = 27
Level 2: Answer is any number that is greater than 20 will make the statement true.
Level 3: 1.) x = 9 / 2.) x = 4
