class 6 Mathematics Chapter 10 The Other Side of Zero solutions
To subtract –3 – (+5), think of it as adding 5 positive tokens to –3, since subtracting a positive number is like moving rightward on the number line. Adding 5 zero pairs to –3 cancels out 5 negatives and leaves –8. Therefore, –3 – (+5) = –8. The zero pairs cancel out the opposing values, and the remaining tokens confirm the result. This process helps visualize subtraction of integers in terms of token movement.
