class 6 Mathematics Textbook Chapter 10 question answer
To add +5 and –8 using tokens, place 5 positive tokens and 8 negative tokens. Cancel out 5 positive and 5 negative tokens, as they form zero pairs. This leaves 3 negative tokens. Therefore, (+5) + (–8) = –3. The concept of zero pairs simplifies integer addition by removing equal positive and negative values, leaving only the remaining unmatched tokens.
