Have you wondered how to solve or add even numbers from 2 until any 2 digit numbers?

Adding even numbers is a difficult task if you do not know the tricks on how to shorten or short cut the process in solving it or if you do not have any calculating machine. Just imagine adding even numbers such as 2 + 4 + 6 + 8 + 10. . . through + 98. It is time consuming. To add this manual at a very easy way, just follow the steps below.

Here are the steps to solve it in an easy way without using a calculator or any calculating machine:

Steps:

1.       Choose any 2-digit even number.

Say, find the sum of even numbers from 2 through 56.

2.     Divide the even number by 2 (or multiply it by 1/2)

56 ÷ 2 = 28 or 56 (½) = 28

3.       Multiply the result by the number next to the result in step 2.

The result of step 2 is 28; multiply it by the number next to it which is 29 (28 X 29) to get 812 which is the sum of all even numbers from 2 through 56.

That is 2 + 4 + 6 . . . + 52 + 54 + 56 = 812

These steps can only be used when you are adding all even numbers below 100.
