Random Thoughts or Whatever

A couple of disturbing reels on simple math popped up. In both, a man asks a bunch of people to solve a simple math problem.
First one: 2 + 2 × 2
2nd one: 3 + 3 × 3
Everyone got the wrong answer for both questions and then insisted that they were correct. Now, it's understandable one might forget the order of operations and just read left to right and get the wrong answer. It happened to me on the first one, then "Oh yeah PEMDAS, Duh!" Worse yet, a lot of people posted comments insisting that the wrong answer was correct.
Order of operations: PEMDAS! In both cases we only have to deal with multiply and add. 2 × 2 = 4 + 2 = 6, 3 + 3 × 3 = 9 + 3 = 12. How important is this? Get it wrong and you could be unwittingly giving someone permission to rip you off. Let's say purchase 3 like items for 3 bucks each and another item for 3 bucks. Your receipt (before sales tax) should look something like this.
Thing-a-ma-jig 1 @ $3 each = $3
Doohickey.......3 @ $3 each = $9
Subtotal...................................$12
What you're actually doing is purchasing 4 items for 3 bucks each. Does anyone really want to pay $6 extra? What if you purchased 4 items at $30,000 each, 3 like items and one different item? Are you okay with having $60,000 stolen from you?
.... and that folks is why order of operations is so very important.

Because it requires acceptance of things that are unseen and unknown.

It also applies to things that are seen and known. When approaching a red light at a busy intersection I have faith the brakes will work, so does everybody else.

I think it means we are stuck in the pastHow come, we change...but our love of music doesn't?
Something to do with digital vs analog vs organic, I'll bet.

Valid point made, SI.
Maybe "prefer" might be a softer assessment ("stuck") for us "Nostalgia's"? For me that word means "no choice", is all.
Tried to listen to the present day Western station this morning, but ALL the tunes sounded the same. It's more of a "drone" with a range of three to four notes. "Country Rap" with a Southern Drawl?

It's all in the rhythm, whether we are conscious of it or not.How come, we change...but our love of music doesn't?

Because they're bugs and they know how to bug you.

I have 3 to 4 Arrow sheet metal sheds with pieces all in one big pile. They sat in my back yard too long that the paper shipping boxes had disintegrated. Some even got a bit rusty. lately I been working to assemble the first one. It had become a big boy Lego project with unreliable or missing instructions. I will probably finish these puzzles in 3 years.
I have also found out the goodness of knee pads for bare ground.

Random thought today...'change'.
I live in a rural area, in a small town, maybe 3000 on a good day...many are Summer people here, so really less.
I tried to visualize what this area is going to look like in the next 100-200 years. From what I can see in the coming era...kinda glad I'm here now in this time period. Mostly a "tourist region" at present with surrounding small farms, but they (town council), are talking 4-6 story condo's for down town. Only the lack of water (right now) is holding up further development. Developers want in!
Wonder what the people 200 years ago would say about this world of today, eh?
"Progress"...is it really a "Pro" concept?
FWIW
