What is Algebra?
Algebra is a branch of mathematics that uses letters and symbols to represent numbers and quantities in equations and formulas. It’s the foundation for almost all advanced mathematics.
Why Learn Algebra?
Algebra helps you:
- Solve real-world problems — from calculating distances to managing finances
- Think logically — develop critical thinking and problem-solving skills
- Prepare for advanced math — calculus, statistics, and more all build on algebra
Basic Concepts
Variables
A variable is a letter (like x, y, or z) that represents an unknown value.
Expressions
An expression is a combination of numbers, variables, and operations:
3x + 52y² - 7
Equations
An equation states that two expressions are equal:
3x + 5 = 14
Solving a Simple Equation
Let’s solve 3x + 5 = 14:
Step 1: Subtract 5 from both sides
3x + 5 - 5 = 14 - 5
3x = 9Step 2: Divide both sides by 3
3x / 3 = 9 / 3
x = 3Step 3: Verify
3(3) + 5 = 9 + 5 = 14 ✓Practice Problems
