Algebra EP1 | Algebra Basics & Collecting Like Terms | Variables, Coefficients & Expressions |

In this episode, we start from the basic ideas of algebra and build step by step towards collecting like terms. You will learn: • How numbers lead to algebra • Variables and constants • Terms and coefficients • Algebraic expressions • What like terms are • How to collect positive and negative like terms • How to simplify mixed expressions • The difference between addition and multiplication in algebra • Common algebra mistakes • A practice question with a full worked solution Examples include: 3x + 5 3x + 5x = 8x 7x - 3x = 4x 4x × 3x = 12x² -4x - 3x = -7x and 5x² - 3x + 4 - 2x² + 7x - 9 + x² = 4x² + 4x - 5 ⏱️ Chapters Algebra EP1 — Introduction From Numbers to Algebra Variables and Constants Terms and Coefficients Algebraic Expressions What Are Like Terms?
