Algebra is about balance; primarily about balance. The universe is about balance; we exist within the universe so we are about balance (simply written). The symmetry of the human body is a form of balance. The process of understanding one another is a form of balance because individuality and uniqueness is every human being. You have to know how to balance; that's what the class is for; what you learn in class will be embedded into your sub-conscious for everyday living.
The variables that are involved with algebra allow you to interchange within life's foundation of change. Many things don't change about life, but creativity and difference keep the world spinning. The power that God bless us with is the ability to set variables to represent some idea; i.e. the ability to think. The essence of thought; the immensity of one's mind when it is controlled with mathematics; there is no other way! The ability to explain mathematics is science. This foundation of change is for your “survival” at a primitive mind state, but more so for your dream's desires. Interchanging variables and energies for what you want out of life; for your contentment and comfort/progression and goal seeking. That's using Mathematics!
