🇬🇧 Equation meaning: English Vocabulary Flash Card

An equation is like a math sentence that says, “This side is the same as that side.” It uses numbers, letters, and symbols like =, +, −, ×, and ÷. The equal sign (=) in the middle means both sides have the same value, even if they look different. For example, 3 + 2 = 5 is an equation because 3 + 2 and 5 are equal. Sometimes an equation has a mystery letter, like x, and you have to figure out what number makes both sides equal. Solving an equation is like solving a puzzle so that both sides match perfectly.
