👉 Box math, also known as boxed notation or square bracket notation, is a mathematical notation system used to represent functions and equations in a compact and structured way. It involves enclosing the variable or expression within square brackets to clearly define its domain, range, and behavior. For example, the function \( f(x) = \sqrt{x-3} \) uses square brackets to indicate that the expression inside (x-3) must be non-negative, thus defining its domain as \( x \geq 3 \). This notation enhances clarity and precision in mathematical expressions, making it easier to analyze and understand complex functions.
