Yesterday, I saw someone online talking about these two numbers, 169 and 81, and I got curious. So, I decided to play around with them a bit.
My Little Experiment
First, I just looked at the numbers. 169 and 81. Nothing special popped into my head at first.
Then, I grabbed my calculator. I started with some simple stuff:
- I added them: 169 + 81 = 250. Okay, that’s a nice, round number.
- I subtracted them: 169 – 81 = 88. Hmm, double eights.
- Multipling time:16981=13689
Then it hit me! I remembered something about square roots from school.
I punched in the square root of 169. Boom! It’s 13. A whole number, how neat is that?
Next, I tried the square root of 81. And guess what? It’s 9! Another whole number. That’s pretty cool.
I started by checking their squares roots, and then I got these two perfect whole numbers.
So basically, that’s all there is to * figured some simple fun, and it reminded me of some basic math stuff I’d forgotten.
