📚 Quick Study Guide

  • 🔢 Variables: A variable is a letter (like $x$ or $y$) that represents a number.
  • Expression: An algebraic expression is a combination of numbers, variables, and operations (like $+$, $-$, $\times$, $\div$).
  • 💡 Evaluating: Evaluating an expression means finding its numerical value by substituting numbers for the variables and simplifying.
  • 📝 Order of Operations (PEMDAS/BODMAS): Remember to follow the correct order: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
  • 📌 Substitution: Replace each variable with its given value.
  • Simplifying: Perform the operations in the correct order to get the final answer.
  • Example: If $x = 3$ and $y = 2$, then the expression $2x + y$ is evaluated as $2(3) + 2 = 6 + 2 = 8$.
