Addition (original) (raw)
Last Updated : 13 Feb, 2026
Addition is defined as the arithmetic operation in which we combine two or more quantities to find the combined value of the quantities. We use the symbol plus (+) to perform addition operations.
Example, find the total marks scored by Adam if he scored 98 in half yearly and 96 marks in the final examination. Then the total marks scored by him in a year is 194 i.e., (98 + 96).
If a person knows addition, they can perform other operations, such as multiplication and subtraction easily.
Real-Life Uses of Addition
Addition is used in many real-life scenarios, whether in simple daily tasks or more complex situations.

- **Shopping: Adding prices of items to find the total cost (e.g., 5+5 + 5+3 = $8).
- **Budgeting: Adding income sources and expenses to calculate total income (e.g., 2,000+2,000 + 2,000+500 = $2,500).
- **Time Management: Adding times of activities to know the total time needed (e.g., 30 minutes + 45 minutes = 75 minutes).
- **Health and Fitness: Adding calories consumed or burned (e.g., 300 + 500 = 800 calories).
Parts of Addition
While performing addition the parts of addiction are,
- **Addend: In addition operation, the numbers that are added are called the addends. For example in the addition of 2 and 3, (2 + 3), 2 and 3 are addends.
- **Addition Symbol: Symbol that represents the addition is the plus sign (+). For example in the addition of 2 and 3, (2 + 3) and (+) represent addition.
- **Sum: Result of the addition operation is called the sum. For example in the addition of 2 and 3, (2 + 3 = 5), 5 is the sum.
Methods for Addition
We have various methods for finding the sum of two numbers or solving addition.
1. Addition On Fingers
Addition operation can be easily performed by using fingers. We use our fingers for finding the sum of two numbers.
Suppose we have two to find the sum of 3 and 5 then we count, till three using our fingers of one hand and then continue to count five fingers using the second hand to find the sum of both. We count all the fingers to find the sum (3 + 5 = 8).

2. Addition on Number Line
A number line is a line that represents numbers (Integers) and we can easily add two or more numbers with the use of a number line.
Suppose we have to find the sum of 5 and 6. Then we must follow the steps added below to find their sum,
**Step 1: Mark 5 on a number line.
**Step 2: We have to add 6 to 5 so we jump six places in the right direction from 5.
**Step 3: Mark the final position(here 11). Thus, we get the sum of 5 and 6 to be 11.
3. Addition By Regrouping
For numbers with only one's digit, we can add them using a number line but the addition of two digits or three digits number using a number line is not feasible as drawing number lines gets bigger and bigger. Then we use addition by regrouping to find the sum of two or more numbers.
- In this method, we write the number in H T O (Hundreds Tens Ones) format and then add one with one, ten with ten and hundred with hundred and so on.
- One thing in this method that we have to remember is if by adding any pair we came across the sum to be greater than 10 then the one's digit is written and the tenth part is carried forward.
Suppose we have to find the sum of 234 and add 249 by regrouping they are added as

Addition Word Problems
**Problem 1: In a class test the marks scored, by Anatika out of 20 are 10, 8, 6, and 11 in English, Maths, Science and Computers respectively. Then find the total marks scored by Anatika.
**Solution:
Marks scored by Anatika
- In English = 10
- In Maths = 8
- In Science = 6
- In Computer = 11
Total marks scored by Anatika = 10 + 8 + 6 + 11 = 35
**Problem 2: Rakesh earns 2000, 2230, 1789, 2341, 1890, 1678, and 2318 rupees in different days of the week chronologically. Then find its total earning.
**Solution:
Rakesh earns in each day of week,
- On Monday = Rs 2000
- On Tuesday = Rs 2230
- On Wednesday = Rs 1789
- On Thursday = Rs 2341
- On Friday = Rs 1890
- On Saturday = Rs 1678
- On Sunday = Rs 2318
Total money earned by Rakesh in a week = 2000 + 2230 + 1789 + 2341 + 1890 + 1678 + 2318 = Rs 14246
