The sum of one-digit numbers can be found as 5 6= 11, the sum of two-digit numbers like 22 44=66, the sum of three digits like 456 124=580 and so on. Sum of one digit, two-digit, and three-digit numbers Now, we will discuss how to find the sum of one-digit numbers, two-digit numbers, three-digit numbers and so on. This is used when we add a long list of numbers. We can also represent the sum by using the symbol ? (sigma). The sum is the result obtained by adding two or more numbers. When we add two or more numbers we use the sign of (plus). In other words, sum is defined as when we put two or more numbers together to give a new result. Thus, it is the property when we put different things together. In Maths, sum is the result obtained by adding two or more numbers. Here, you will learn more about the sum, how to find the sum in different situations. The total amount of the prices of all items is called the sum. We ask the shopkeeper to add the prices of all the items so that we can pay the money. For example, when we go to the market and buy several things. We also use this term in our daily lives. The term Sum in Math is used when two numbers are added together and the result is obtained. The Series Which We Get by Adding the Terms of Geometric Sequence is Known asįor the Sequence 1,7, 25,79 ,241 ,727 the General Formula for a n is Few summations require infinite terms.įor these reasons, the summation is represented as \. There can be two terms, thousands of terms, or many more. In other words, summation notation enables us to write short forms for the addition of very large numbers for a given date in a sequence.Ī summation usually requires an infinite number of integrals. Summation notation is needed to represent large numbers. Summation is an important term in Mathematics as it calculates many terms of a given sequence. It is usually required when large numbers of data are given and it instructs to total up all values in a given sequence. The summation is a process of adding up a sequence of given numbers, the result is their sum or total.
