tízes szomszéd

Thanks for that. I've summarised my postings from last night. I think "the neighbouring pair of multiples of 10" would be a better term for English readers, but "neighbouring multiples of ten" is certainly understandable.

It does not.

What it actually says is:

1. 610 and 620 are the neighbouring multiples of ten for the following numbers: 611 .. 619

2. "We were talking about numbers next to eachother when we were learning about numbers. Now, apart from neighbouring numbers (multiples of one), we are going to learn about neighbouring multiuples of 10.

3. We are going to illustrate how to find neighbouring multiples using a number line. First, we have the children found neighbouring numbers (multiples of one). The children already know this. Subsequently, we look for the neighbouring multiples of ten. Let us identify that on the number line, the lower neighbouring multiple of ten is to the left from the number, the higher multiple of ten is to the right from the number.

I hope it helps. However, I am not going to write any more about this, as I have work to do.

"Mely számok tízes szomszédai a 610 és a 620?"
in English
Which numbers' neighbouring multiples of ten are 610 and 620?

So this proves my point.

Google throws this up "Mely számok tízes szomszédai a 610 és a 620?" And the answer given is "611,612,613,614,615,616,617,618,619" which I certainly wouldn't have expected.

"A számokkal való ismerkedés során már beszéltünk az egymás melletti számokról, a szomszédokról. Most megtanítjuk az egyes szomszédok mellett a számok tízes szomszédait is."

"A számegyenes segítségével szemléletessé tesszük a számszomszédok keresését. Elõször az egyes szomszédokat kerestetjük meg, ezt már tudják a gyerekek. Ezt követõen a tízes szomszédok keresését végezzük. Állapítsuk meg, hogy a kisebbik tízes szomszéd a számegyenesen a számtól balra, a nagyobbik tízes szomszéd tõle jobbra található."

These also suggest to me that a range is actually what is being asked for.

A game with schoolchildren.

A tízes számszomszédokat gyakorolhatjuk számkártyák segítségével. Számkártyákat osztunk ki. Felteszünk egy kerek tízes számkártyát a táblára. Álljon fel, akinek a táblára tett szám
• a tízes számszomszédja,
• a kisebb tízes számszomszédja,
• a nagyobb tízes számszomszédja.

Zsofia also proposed this (something similar). I agree that in British education, these terms are not so popular, maybe they teach these in a different way. However, it is extremely important that "számszomszéd" means two results, not only one. Of course, you can specify lower or higher, but without this specification, it always has two results. What is more, sometimes, these two does not even include the nearest ten, as the two results for 40 would be 30 and 50.

And I DID understand your point, but it is still unfair, imho.

DLyons: some of the sites are utterly slow, yes, but most of them are OK.
And the question you've posted basically asks the reader to list the numbers between those two numbers - so it is the other way round compared to "our" problem.
So all in all János' answer might be correct, but to be honest I've never heard the expression "neighbouring multiples of ten" before. But well, I've never seen 10 billion pounds either :).

22:11 Sep 19, 2014 

Okay, I am off to sleep now. I promise to look at Dlyon's link tomorrow morning.

22:08 Sep 19, 2014 

Not understanding was exactly my point, Zsófia, thank you for figuring it out. It was a hit below the belt, a crime of passion! Next time I will count to the first multiple of ten before posting. Sok sikert neked Zsófi a további guglizáshoz.

21:55 Sep 19, 2014 

I gave the other answer to this question - it was pretty similar to yours, but I have deleted it because János was right in the sense that "rounding to the nearest multiple of X" means we only get one right answer, and in this case we need both nearest tens, so in regards of 43 the right answer is 40 AND 50.
On the other hand, I find Janos's reaction totally unacceptable, "Lát om po ntot sze rezt él vagy 50 nye lvpár ban, ügy es vagy na gyon, vajon ezt a m ond atom lefo rd ítja agug li for d ítód; ne oko skodjbe le máso k ny elv ébe" - is definitely NOT an answer that a professional, qualified translator would provide to another fellow translator's comment. Making sure the other partner won't understand it so they won't be offended is simply a hit below the belt.

Sorry, I did not mean to imply that you posted it again on purpose. The like works fine for me, I don't know why your browser cannot open it.

21:35 Sep 19, 2014 

I am not "posting it again" - I've just seen the question with a single answer. Maybe you're right (there isn't much context) but "Identify the neighbouring multiples of ten" is definitely an unusual operation in English school work. Your link doesn't open for me, so I can't check whether it's done in Hungarian schools.

The asker will decide which of the different calculations gives the correct answer.

21:22 Sep 19, 2014 

So here is the explanation.
Someone already posted an answer very similar to yours but it was deleted. That is why I don't like when someone removes an answer: someone else comes along and posts it again.

There is a difference between rounding and identifying the neighbouring multiples of ten.
Rounding (kerekítés in Hungarian): identifying the closest multiple of ten/hundred etc.
Tízes szomszéd (neighbouring multiples of ten): e.g. 40 - 50 in case of 43. Here you need to identify one multiple of ten below and one above the number concerned.

In our case the correct answers are 40 - 50; 50 - 60; and 60 - 70.
