In mathematics, the term sum refers to the result of adding two or more numbers together. It is one of the basic operations in arithmetic. For example, if you add 3 and 5, the sum is 8. This can be written as:
3 + 5 = 8
The numbers being added are called addends, and the result is the sum. Summation is a fundamental concept that is used in various areas of math, including algebra, calculus, and more.
Here are a few examples to illustrate the concept:
- 2 + 2 = 4
- 7 + 3 = 10
- 12 + 15 = 27
Understanding the concept of sum is essential for solving more complex mathematical problems. It is the foundation upon which many other mathematical operations are built.
