When you add a negative number, it’s like subtracting! So, if we start with 325 and take away 122, we can think of it like a fun game of tug-of-war. 325 will lose some ground but still come out a winner. The result is !

To double-check, you can break it down: Imagine 325 as 300 + 25. Taking away 122 means first subtracting 100 from 300, leaving you with 200, and then subtracting 22 from 25, which gives you 3. Adding them back together gives you 200 + 3 = 203. Voilà!
