class 6 Mathematics Textbook Chapter 10 question answer
On a number line, subtraction is visualized as movement: left for negative results and right for positive. For instance, 5 – 8 shifts 3 steps left, resulting in –3, while 8 – 5 shifts 3 steps right, giving 3. This approach helps interpret differences between numbers as distances or movements. By combining subtraction with addition concepts, the number line provides a clear representation of mathematical operations, making abstract ideas more concrete for learners.
