📚 Quick Study Guide

  • 🧮 Variable: A symbol (usually a letter) representing an unknown number.
  • Constant: A fixed value that doesn't change.
  • ✖️ Coefficient: A number multiplied by a variable.
  • ✍️ Algebraic Expression: A combination of variables, constants, and arithmetic operations (addition, subtraction, multiplication, division).
  • Terms: Parts of an algebraic expression separated by + or - signs.
  • 🤝 Like Terms: Terms that have the same variable raised to the same power; they can be combined.
  • 💡 Simplifying Expressions: Combining like terms to make the expression shorter and easier to work with. Remember to follow the order of operations (PEMDAS/BODMAS).
  • 🔑 Distributive Property: $a(b + c) = ab + ac$
