Algebra Foundations

Build confidence with expressions, equations, and inequalities — the core tools for everything ahead.

Why it matters

  • Expressions → translate words into math you can work with.
  • Order of Ops → get the same correct answer every time.
  • Equations → solve real problems by finding the unknown.
  • Inequalities → model ranges, limits, and “at least / at most.”
  • Number line graphs → visualize solution sets quickly.
