Okay, so yesterday I was messing around and got this random idea: “What’s 87 minus 15?” Sounds simple, right? But I wanted to make it a bit more… involved.
First, I grabbed a piece of paper and a pen. Old school, I know. I could’ve just used my phone’s calculator, but where’s the fun in that? I wrote down “87 – 15” in big, bold numbers.
Getting Down to Business
- I started with the ones place: 7 minus 5. Easy peasy, that’s 2. I jotted that down.
- Then, I moved to the tens place: 8 minus 1. Boom, that’s 7. I wrote that down next to the 2.
And there it was, staring back at me: 72. Seriously, that’s all there is to it. 87 – 15 = 72. I double-checked it with my phone’s calculator, just to be sure. Yep, 72.

I felt a tiny bit silly for making such a big deal out of a simple subtraction problem, but hey, sometimes it’s fun to go back to the basics. It reminded me of elementary school, and honestly, it was kind of relaxing. No fancy algorithms, no complex equations, just plain old subtraction.
