Part 5/7:
Should we express -3 / -3 as (-1 * 3) / (-1 * 3), we can further dissect it as:
(-1) * (3 / 3) = (-1) * 1 = 1.
This alignment of division also concludes negativity cancels out, yielding a positive. Hence, the rule that states negative times negative results in a positive holds up under scrutiny.
Applying This Concept to Real-Life Scenarios
Now, let's apply our understanding of negative times negative equaling positive into a practical real-world scenario. Imagine a situation where you have $4 but owe $8.
In this case, we can denote your balance as:
- Net balance = $4 - $8 = -$4.
If, for some reason, the debt of $8 is canceled (a negative becoming absent), we can visualize this situation as removing the negative debt:
