Beta, when teacher said minus times minus is plus, I imagined my friend Ramesh returning my marbles. If I owe him three marbles, that's –3, but if he forgives the debt, that's –(–3) which means plus three marbles back with me! So –3 – (–5) means if I owe three but you remove five from my debt, I actually get two marbles. It's like when my sister secretly pays my library fine – the worry is gone and I have something extra.
