sum
In mathematics, the term “sum” refers to the result of adding two or more numbers together
In mathematics, the term “sum” refers to the result of adding two or more numbers together. It is a basic operation in arithmetic and is represented by the plus sign (+). The sum is also commonly referred to as the total.
For example, if we have the numbers 3 and 5, their sum is 3 + 5 = 8. In this case, 8 is the sum of 3 and 5.
The concept of sum can also be extended to include adding more than two numbers. For instance, if we want to find the sum of 2, 4, and 6, we add them together: 2 + 4 + 6 = 12. Here, 12 is the sum of 2, 4, and 6.
In a more generalized form, the sum can be expressed using the sigma (∑) notation, where a series of numbers are added together. For instance, the sum of the first n natural numbers can be denoted as:
1 + 2 + 3 + … + n = ∑(i) from i=1 to n
Here, i represents each individual term in the series, and we add all the terms together to find the sum.
The concept of sums is widely used in many branches of mathematics, including algebra, calculus, and number theory. It helps us understand and solve various mathematical problems by finding the total or combining individual quantities.
