### The sum of values is called addition.

The sum of values is called addition. To know the total values, one needs to add two or three different values.

S u m o f T w o N u m b e r s = F i r s t N u m b e r + S e c o n d N u m b e r S u m o f T w o N u m b e r s = F i r s t N u m b e r + S e c o n d N u m b e r

For a list of values like  a 1 , a 2 , a 3 ,……….a n , the formula is

A = \$a_{1}\$ + \$a_{2}\$+ \$a_{3}\$…….\$a_{n}\$

First number = 67, second number = 15

Sum = First number + Second number

Example 2: Find the sum of 413, 78 and 350.

Solution:

413

+ 78

+ 350

——–

841

Explanation:

The digits at units place are 3, 8, 0

3 + 8 + 0 = 11

Hence, keep1 and carry 1 for the addition of digits at tens place

Sum of digits at tens place = 1 + 7 + 5 + 1(carried) = 14

Here, keep 4 and carry 1 for the next addition of digits at hundreds place

Sum of digits at hundreds place = 4 + 3 + 1 (carried) = 8

Therefore, the result is 841.

For example, when you have 10 +5, you just regroup the numbers according to the place value of the number. If the number is in the ten’s place, then place the second number’s ten’s value under that. Similarly, do that for hundreds, thousands value.

Now start adding the terms from the extreme right and carry over the extra digit to the next column.

Suppose you have to add two numbers, the addition formula is mentioned below.

X and Y are two given number then, the sum Z is given by

32 + 16

Here in the ten’s place, we have 3 and 1

On the one’s place, we have 2 and 6, so we place them as given below:
