FAQs on What is Addition? Video Lecture - Mathematics for Class 1: NCERT

1. What is addition?
Ans. Addition is a mathematical operation that combines two or more numbers to give a total or sum.
2. How do you perform addition?
Ans. To perform addition, you simply add the numbers together. Start by writing the numbers vertically, aligning the digits in each place value column. Then, add the digits in each column from right to left, carrying over any excess to the next column if necessary.
3. What are the properties of addition?
Ans. The properties of addition include commutativity (changing the order of numbers does not change the sum), associativity (changing the grouping of numbers does not change the sum), and the existence of an identity element (adding zero to any number leaves it unchanged).
4. Can you give an example of addition in real life?
Ans. Certainly! Adding prices while shopping, calculating the total number of goals scored by a soccer team in a season, or determining the sum of ingredients while cooking a recipe are all examples of addition in real life.
5. How is addition different from subtraction?
Ans. Addition is the process of combining numbers to find the total or sum, while subtraction is the process of finding the difference between two numbers. In other words, addition increases the value, while subtraction decreases it.
