Look at what you can do now:
Solve linear equations by isolating variables and balancing both sides
Simplify expressions using distributive property, combining like terms, and factoring
Solve systems of equations with substitution or elimination
Apply the quadratic formula and check the discriminant
Manipulate inequalities correctly (remembering to flip when multiplying by negatives)
Use algebra to analyze algorithm complexity and solve optimization problems
Algebra is the language of problem-solving. Every equation you solve in code starts with algebraic thinking. You have the tools now.
