Sum Examples on Summation

Example 1: What is the sum of the first ten positive integers?

Solution:  The first thing for the solution you must know is what are integers-

Integers- An integer is a whole number that can be positive, negative or zero. The symbol of an integer is ‘Z’.

 First 10 Positive Integers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

 Addition of positive integers- 1+2+3+4+5+6+7+8+9+10= 55.

Example 2: What is the sum of the first 5 Even numbers?

Solution:

We need to know the definition of even numbers to solve this problem.

First 5 Even Numbers:  2, 4, 6, 8, 10

Addition of Even numbers- 2+4+6+8+10 =  30.
