FAQs on Examples: Subtraction of Integers- 1 Video Lecture - Class 6

1. What is subtraction of integers?
Ans. Subtraction of integers is a mathematical operation that involves finding the difference between two integers. It is the process of taking away one number from another.
2. How do you subtract integers with different signs?
Ans. When subtracting integers with different signs, we subtract the absolute values and keep the sign of the number with the greater absolute value. For example, to subtract -5 from 3, we subtract 5 from 3 and keep the negative sign, resulting in -8.
3. Can you explain the concept of borrowing in subtraction of integers?
Ans. Borrowing in subtraction of integers is similar to borrowing in regular subtraction. When the number on the right is larger than the number on the left, we "borrow" from the next place value. For example, in 302 - 58, we borrow from the tens place and make the hundreds place 1 less. This results in 212.
4. How do you subtract integers using a number line?
Ans. To subtract integers using a number line, we start at the first number and move to the left by the absolute value of the second number. If the second number is negative, we move to the right instead. The final position on the number line gives us the result of the subtraction.
5. What are some real-life examples where subtraction of integers is used?
Ans. Subtraction of integers is used in various real-life situations, such as calculating temperature differences, finding the change in elevation, determining the financial gain or loss, and measuring distances between two points in opposite directions.
