Socks and Like Terms | Algebraic Expressions

What is 3x + 2y + x? If you said 6xy, this video is for you. In algebra, like terms are like socks: you only pair up the ones that match. Let's tidy up the drawer! In this video you'll learn: ✔ Parts of a term: sign, coefficient, variable part and exponent ✔ Monomial, binomial, trinomial and the degree of an expression ✔ What like terms are (and which ones are NOT) ✔ Combining like terms, including negative signs ✔ 3 examples from easy to exam level, the x + x = x² trap and a 5-second challenge ✔ The perimeter of a yard, with algebra ⏱️ CHAPTERS 0:00 The sock drawer: 3x + 2y + x 0:34 Parts of a term 1:07 Monomial, binomial, trinomial and degree 1:38 Like terms 2:07 Combining like terms 2:35 Combining with negative signs 3:10 Example ladder 4:06 The trap: x + x is not x² 4:37 5-second challenge 5:15 Real world: fencing a yard 5:52 3-card recap 6:12 Wow fact: where + − = came from ◀️ Previous: AL-01 · What Is a Variable? ▶️ Next: AL-03 · Exponent Rules 📚 Full playlist: The X Lab · Algebra 1 💬 Tell me in the comments: what is 4x + 3 − x + 2? 👍 If this helped, hit like and subscribe — new visual math every week. 🇪🇸 ¿Prefieres en español? → @AlgebrayTrigonometria #math #algebra #liketerms #algebraicexpressions #algebra1 #mathhelp #SATmath
