Algebra Fundamentals

Why Algebra Matters

Algebra introduces variables—letters that stand for numbers—to help you solve for unknowns. It's essential for forming equations, understanding patterns, and solving word problems on the GMAT.

Core Skills

  • Simplifying expressions
  • Solving linear and quadratic equations
  • Working with inequalities
  • Applying formulas

Using Algebra in Life

Algebra is handy when you want to figure out how long it’ll take to save for a new phone or split a bill among friends.

Tips for Success

  • Isolate variables step by step.
  • Check your solutions by plugging values back into the original equation.

Avoid Pitfalls

  • Don’t forget to flip the inequality sign when multiplying or dividing by a negative number.
  • Watch out for extraneous solutions in quadratic equations.

Examples

  • If 3x + 5 = 20, then 3x = 15, so x = 5.

  • The area A of a rectangle with length l and width w is given by A = l × w. If A = 24 and l = 6, then w = 4.

In a Nutshell

Algebra uses variables and equations to solve problems and find unknown values.
