Fundamental Concepts (Including Fundamental Operations)
Fundamental algebra concepts include understanding variables, expressions, and performing the four basic operations on algebraic terms.
Core concept
Algebraic expressions combine numbers, variables, and operations, like 5x + 3y - 2, representing mathematical relationships.
How it works
We can add or subtract like terms (same variable and power), such as 3x + 2x = 5x, but not unlike terms like 3x and 2y.
Why it matters
Multiplication of algebraic terms combines coefficients and variables, like 2x × 3y = 6xy.
Key detail
Mastering these fundamental concepts is essential before moving to more advanced algebra topics like equations and factorisation.

Quick notes
• Algebraic expressions combine numbers, variables, operations.
• Example: 5x + 3y - 2.
• We add/subtract like terms only.
• 3x + 2x = 5x is valid; 3x + 2y is not combined.
• Multiplication combines coefficients and variables.
• 2x × 3y = 6xy.
• These are fundamental algebra concepts.
• Mastery prepares for advanced algebra.
