Adding Several Numbers

Introduction to Adding Several Numbers:

An integer is a set of whole numbers. Whole numbers above zero is said to be positive numbers denoted as ‘+’ sign and whole numbers below zero is said to be negative numbers denoted as ‘-‘. A number with zero is said to be neither negative nor positive and it does not have any sign in math. In addition there may be different digits numbers to add. The positive numbers can be written with or without the sign. Let us see about adding numbers in this article.

Rules for Adding Several Numbers

For adding several numbers, write the numbers one by one in column-wise.
Write the numbers of one’s digit in the right side of the column.
Write the numbers of tens place; hundred’s place one before the unit’s place and ten’s place in a row.
First add the one’s place and the sum of one’s place is more than one digit add the last digit to the columns top of the ten’s place, and vice versa.

Example Problems to Adding Several Numbers

Example 1:


Adding several numbers 6 + 7 + 3 + 5 + 9

Solution:

Adding all these numbers we get the carry of 3 and write before the number zero.

6

7

Example 2:

Adding several numbers 45 + 23 + 78 + 55+ 68+ 19

Solution:

Adding all these numbers we get the carry of 3 to the ten’s place column and add it to the ten’ place digit.

45

23

78

Example 3:

Adding several numbers 3564 + 4767 + 2433 + 7548

Solution:

Add all these numbers together to get 2 carry by adding one’s place and then carry of 2 by adding ten’s place and then the carry of 2 by adding hundred’s place and adding thousands place we get the carry of 1 it can be placed before the one’s digit by adding thousand place sum because there is no place digits before the thousands place.
