FAQs on Subtraction of Integers with and without Using Number line Video Lecture - Crash Course for Class 6

1. What is the process of subtracting integers using a number line?
Ans. To subtract integers using a number line, you start by locating the first integer (the minuend) on the line. Then, you move to the left if you are subtracting a positive integer or to the right if you are subtracting a negative integer. The point where you land after moving represents the result of the subtraction.
2. How do you subtract a negative integer from a positive integer?
Ans. When you subtract a negative integer from a positive integer, it is the same as adding its absolute value. For example, if you have 5 - (-3), you can rewrite it as 5 + 3, which equals 8.
3. Can you explain how to subtract two negative integers?
Ans. To subtract two negative integers, you can think of it as adding their absolute values. For example, if you have -4 - (-2), this can be rewritten as -4 + 2, which equals -2. You move to the right on the number line because you are adding a positive value.
4. What is the result of subtracting a larger integer from a smaller integer?
Ans. When you subtract a larger integer from a smaller integer, the result will be a negative integer. For example, if you have 3 - 5, you can visualize this on a number line where you end up at -2.
5. How can we check our subtraction of integers for accuracy?
Ans. You can check your subtraction of integers by adding the result to the integer that was subtracted. If the sum equals the original minuend, then your subtraction is correct. For example, if you calculated 7 - 4 = 3, you can check by adding 3 + 4, which gives you back 7.
