Very easy to solve, just like it is easy to solve many other ones once you know the tricks.

Yeah, read it in another comment. Why do you think doing calculations in your head is brute-forcing? Many people can do it flawlessly, without even knowing of these "tricks". They just know. Is that brute-force?","comments":[{"id":45923159,"user":"jabbywocker","time":1763086967,"time_ago":"3 months ago","type":"comment","content":"

You are not replying to what I said. I am not going to repeat myself, see the parent comment you replied to.","comments":[{"id":45927537,"user":"Izkata","time":1763133151,"time_ago":"3 months ago","type":"comment","content":"

Your original comment completely missed the point of what it was replying to, you phrased it like you were correcting them but you were actually in agreement and didn't seem to realize it. They tried to clarify when you asked and when you responded you assumed they had the opposite viewpoint from what they actually have.","comments":[{"id":45936167,"user":"johnisgood","time":1763198765,"time_ago":"3 months ago","type":"comment","content":"

I replied to "Can you try calculating 101 * 70 in your head?".

Yes, many people can successfully calculate it through learned tricks or no learned tricks.

That is all I am saying. And my question is: how is calculating it in your own head brute-force, especially if done without such tricks?

No need to complicate it, answers to my question would suffice.","comments":[{"id":45939170,"user":"Izkata","time":1763228913,"time_ago":"3 months ago","type":"comment","content":"

> how is calculating it in your own head brute-force

Doing this calculation in your head is not brute force, which was their entire point. Their math question was an example of why the brain isn't brute-forcing solutions, replying to this:

And I posted a link to a book that helps with mental math. Does it make it brute force if I know some mental math tricks?

In any case, I am not sure why he kept on telling me that you do not solve it through brute-force because that is not what I said.","comments":[],"comments_count":0,"level":9,"url":"item?id=45992358"}],"comments_count":1,"level":8,"url":"item?id=45939170"}],"comments_count":2,"level":7,"url":"item?id=45936167"}],"comments_count":3,"level":6,"url":"item?id=45927537"}],"comments_count":4,"level":5,"url":"item?id=45925745"}],"comments_count":5,"level":4,"url":"item?id=45923159"}],"comments_count":6,"level":3,"url":"item?id=45912350"}],"comments_count":7,"level":2,"url":"item?id=45909195"}],"comments_count":8,"level":1,"url":"item?id=45906887"}],"comments_count":9,"level":0,"url":"item?id=45904808"}],"comments_count":10,"url":"item?id=45904347"}
