[Expressions] Simplify \( x+x+x+x \)

You can simplify the expression by combining like terms! Since you have four \( x \)s being added together, you can express this as \( 4x \). Easy peasy, right? This is a common technique in algebra that makes expressions neater and easier to manipulate! In everyday life, simplification comes in handy beyond math, too! For instance, if you’re tidying up your closet and find multiple identical shirts, instead of saying you have four shirts, you could say, “I have four of those shirts!” This makes your statement clearer and more concise, just like simplifying algebraic expressions!
