Resta is a mathematical operation that involves subtracting one number from another. It is commonly used in arithmetic to determine the difference between two values. For example, if you have 10 apples and you give away 3, the resta helps you find out how many apples you have left, which would be 7. In everyday life, resta can be applied in various situations, such as budgeting or measuring distances. Understanding how to perform resta is essential for solving problems and making informed decisions, whether in school, work, or daily activities.
