Algebra Basics for Teens: A Simple Study Guide
1. What is Algebra?
Algebra is a branch of math that deals with symbols (like and ) and numbers. Instead of just
solving basic arithmetic problems, algebra helps us find unknown values and create formulas.
2. Variables and Constants
Variables: Letters (like or ) that represent unknown numbers. Example: , where is the unknown.
Constants: Fixed numbers that do not change. Example: In , the number 5 is a constant.
3. Basic Operations in Algebra
Algebra follows the same basic operations as arithmetic:
Addition: (Solve by subtracting 3 from both sides)
• Subtraction: (Solve by adding 4 to both sides)
• Multiplication: (Solve by dividing both sides by 3)
• Division: (Solve by multiplying both sides by 2)
4. Solving Simple Equations
The goal in algebra is to find the value of the variable.
