Subtraction is one of the four basic arithmetic operations, alongside addition, multiplication, and division. It involves taking one number away from another. The result of a subtraction operation is called the difference. In a subtraction expression, the number from which another number is taken is called the "minuend," the number that is being subtracted is called the "subtrahend," and the result is known as the "difference.
Differential calculus is a branch of calculus that focuses on the concept of the derivative, which represents the rate at which a quantity changes. It deals with the study of how functions change, and it provides tools to analyze the behavior of functions through concepts such as slopes of curves, tangent lines, and optimization. Key concepts in differential calculus include: 1. **Derivative**: The derivative of a function at a given point quantifies the instantaneous rate of change of the function with respect to its input variable.
Goal difference is a statistical measure used in sports, particularly in soccer (football), to determine the relative performance of teams in a league or tournament. It is calculated by subtracting the total number of goals conceded by a team from the total number of goals scored by that team.
The symmetric difference of two sets is a concept in set theory that represents the elements that are in either of the sets but not in their intersection. In simpler terms, it includes the elements that are unique to each set.
