An equation is a mathematical statement that asserts the equality of two expressions or values. It consists of an equal sign (=) connecting two sides, with variables, numbers, and mathematical operations on both sides.
Equations are fundamental in mathematics, used for solving unknowns, modeling relationships, and expressing various quantitative concepts.
They come in different forms, including linear, quadratic, and trigonometric equations, and play a vital role in fields such as physics, engineering, economics, and science.
