FAQs on Mathematical Operations Video Lecture - CSAT Preparation - UPSC

1. What are the four basic mathematical operations?
Ans. The four basic mathematical operations are addition, subtraction, multiplication, and division.
2. How do you perform addition and subtraction of numbers?
Ans. To perform addition, you simply add two or more numbers together. For example, adding 2 and 3 gives you the result of 5. Subtraction, on the other hand, involves subtracting one number from another. For example, subtracting 3 from 7 gives you the result of 4.
3. What is the difference between multiplication and division?
Ans. Multiplication is the process of combining two or more numbers to get a product. For example, multiplying 2 and 4 gives you the result of 8. Division, on the other hand, is the process of splitting a number into equal parts or finding out how many times one number is contained within another. For example, dividing 10 by 2 gives you the result of 5.
4. How do you perform multiplication and division of numbers?
Ans. To perform multiplication, you simply multiply two or more numbers together. For example, multiplying 3 and 4 gives you the result of 12. Division involves dividing one number by another. For example, dividing 15 by 3 gives you the result of 5.
5. Can you give an example of a mathematical expression involving all four basic operations?
Ans. Yes, an example of a mathematical expression involving all four basic operations is: (2 + 3) x 4 / 2 - 1. In this expression, we first perform the addition of 2 and 3, which gives us 5. Then we multiply the result by 4, giving us 20. Next, we divide 20 by 2, resulting in 10. Finally, we subtract 1 from 10, giving us the final result of 9.
