Question 1 Try to subtract: –3 – (+5). How many zero pairs will you have to put in? What is the result?We do follow these steps First make –3 using tokens We have to remove 5 positive tokens But we have only negative tokens So, we add 5 pairs of positive and negative tokens We can do that because (+1) + (–1) = 0 Now, remove 5 positivetokens Remaining tokens is our answer ∴ –3 – (+5) = (–8) And, we had to add 5 zero pairs
