ADDITION OF THREE SINGLE DIGIT NUMBER

ADDITION OF THREE SINGLE-DIGIT NUMBER -

Method of Addition of three single digit number -

1. Start by choosing three single-digit numbers. Let's use a, b, and c to represent the three numbers.
2. Begin by adding the first two numbers, a and b. Add the ones place digits of a and b together. If the sum is less than 10, write down the sum as the ones place digit of the result. If the sum is 10 or greater, write down the ones place digit of the sum and carry the tens place digit to the next step.
3. Now, add the carried-over tens place digit from step ﻿2﻿ to the third number, c.Add the tens place digit (if any) to c.Write down the ones place digit of the sum as the tens place digit of the result.
4. Finally, write down the ones place digit of the sum from step 2 as the ones place digit of the result.

Let's illustrate this process with an example using the numbers 3, 7, and 5:

Step 1: Choose the numbers a = 3, b = 7, c = 5

Step 2: Add the first two numbers 3 + 7 = 10 Write down 0 as the ones place digit and carry over 1 to the next step.

Step 3: Add the carried-over digit to the third number 1 + 5 = 6 Write down 6 as the tens place digit.

Step 4: Write down the ones place digit Write down 0 as the ones place digit.

Therefore, the sum of 3, 7, and 5 is 60.

By following this logical approach, you can add any three single-digit numbers.
