FAQs on What is Addition? Video Lecture - Mathematics for Class 3: NCERT
| 1. What is addition? |  |
Ans. Addition is a mathematical operation that combines two or more numbers to give a total or sum. It is represented by the "+" symbol and is commonly used to find the total quantity or value when multiple quantities are combined.
| 2. How do you perform addition? | |
Ans. To perform addition, you simply need to add the numbers together. Start by aligning the digits vertically, with the ones place aligned with the ones place, the tens place aligned with the tens place, and so on. Add the corresponding digits together, carrying over any excess to the next column if needed, until all the digits have been added.
| 3. Can you give an example of addition? | |
Ans. Sure! Let's say we want to add the numbers 25 and 17. We align the digits vertically:
25
+ 17
------
42
So, the sum of 25 and 17 is 42.
| 4. What are some properties of addition? | |
Ans. Addition has several important properties. These include the commutative property, which states that changing the order of the numbers being added does not change the sum. For example, 2 + 3 is the same as 3 + 2. Another property is the associative property, which states that changing the grouping of the numbers being added does not change the sum. For example, (2 + 3) + 4 is the same as 2 + (3 + 4).
| 5. Can addition be used with other mathematical operations? | |
Ans. Yes, addition can be used in conjunction with other mathematical operations. For example, addition is often used with subtraction to find the difference between numbers. It can also be used with multiplication and division to perform more complex calculations.
