If this were some young student on here, I’d agree that it’s reasonable.

Mr. BB isn’t a young student; he’s an old Blarney Bag who throws BS at questions until some of it sticks.  Mr. BB didn’t mistake the symbol for a minus sign; he’s not that blind, and there is a properly used minus sign in the question, so it’s unlikely the asker confused the two symbols.

 

Mr. BB chose to use it because he understands the function and it gives “a solution.” 

He’s continued to throw BS on it–on this thread and here, where he created another post with the same question.   

For the psychology behind this behavior, see this:  https://web2.0calc.com/questions/what-is-the-sum-of-the-odd-numbers-from-1-to-387#r2

 

I’ve seen these types of questions on GMAT forums.

This question, as asked, has no solution.

 

Here’s a list of squares of concatenated numbers (b_a)

 

b   a    concatenated  square

0    1         1                    1
1    2        12               144
2    3        23               529
3    4        34             1156
4    5        45             2025
5    6        56             3136
6    7        67             4489
7    8        78             6084
8    9        89             7921

 

 

45 and 56 have squares where the (a) digit is the final digit of the square, but this is not in the form of (71a).

Mr. BB seems like a phage on this forum, but I suppose in the scheme of things, that Mr. BB’s posts are just weeds, with annoying flies, in the gardens of Camelot. The students will have to learn to recognize them and treat them accordingly.

 I wonder who could have posted this BLARNEY.

 Who could it be?

 

Now, let me tink about it ...

I know, I know!  It’s THE BLARNY BANKER! ... It’s THE BLARNY BANKER!

 

There are psychology texts describing visual comprehension: What a person doesn’t understand he cannot see, so he will see what he can understand.  The word, “see” in this context does not refer to comprehension it refers to literal vision.

 

You (usually) understand arithmetic and geometric progressions, so this is what you see.  It’s WRONG (here), but you see it clearly.

 

In this post, https://web2.0calc.com/questions/help-me-please_14591#r1

You see a minus sign, because that is what you understand, so that is what you use to “solve the problem. That is WRONG, too.

 

You should be pleased Mr. BB, I’ve used you (in context of your posts) in no less than four research papers: Cognitive learning, abnormal behaviors, analysis, and Learning curves: Statistical analysis by age groups – aka Teaching Old Blarney Bankers New Tricks.

For case examples, I refer to you as Mr. BB, instead of Mr. X.
