👉 The term "modulus" is a mathematical concept that refers to the remainder obtained after dividing one number by another. It is often used in algebra, particularly in solving equations and finding the inverse of a function. The modulus of a number can be thought of as the distance from the origin on a number line. For example, if we divide 12 by 3, the result is 4, and the remainder when divided by 3 is 0, so the modulus of 1
