Nikolai Krylov:

Uh-huh, then why did the admin lift the ban you imposed? ;)

Because he's kind.

 


It seems to be without politics, but the tone and some of the grimaces seem suspicious. We need the opinion of the local expert community.

A psychiatric evaluation would be more appropriate. The grimaces are very telling.

Andrey F. Zelinsky:

nonsense, not advice -- 40/300*100 (2 operations)

nonsense advice -- 40/10, 300/10, 4*30 (3 operations)

Andrew, there's something wrong here... Did you do the math before? ....

 
Alexey Viktorov:

You have no proof that he wrote it, or wrote it that way :)

It's not about the number of operations, it's about the quality of the operations. Division/multiplication by 10 is a very simple operation.

Then rephrase the problem "find 40% of 300" to "find 43% of 367". -- and dividing each number by 10 in no way changes the quality of the operations, on the contrary, it makes them harder.

We are not talking about universal solutions, but about some special cases where the solution can be found easier and faster than in the general case.
