Q&A - P3 Math

[kiasimom]

Errrr. atutor,

When I work backwards, the answer is not right?

If Daisy is 17, Suling will have 8.5 pencil??
And when I add up everything, it doesn’t come up to 134.

Hi ks2me,
Thanks for your answer. It is correct, but I don't understand why for SL with U + 8, each of the Unit in R is also U + 8?

8 is taken out only once from R, so how come U + 8 appears 3 times for R?
Shouldn't it be only once?

Please enlighten. Thank you.

U is the first basic unit of what Daisy has.

So with reference to Daisy, Sulin has U+8 when Rose gives 8 to Sulin. (exactly following the statement given)

Then it says, Rose has 3 times as many as Sulin. (So you don't worry about Rose's 8 given away but look at Rose with reference to Sulin as 3 times)

So if SuLin is (U+8 ), then Rose will be 3 times of that, hence U+8 is shown on the model diagram 3 times.

If you want to see with reference to Rose, it should be -8, not +8 and then the assumption of U will be different, it will not be Daisy's unit.

No problem, you are welcome. It takes a while to get used to this, I also learn my way here.

You thought right in the first place. Pardon the pun. :lol: Take for example a given set of numbers - 18452. For place value, it means how much the digit 8 represents which in this case 8000 or 8 thousands. Another way this question is asked is \"What does the digit '8' stands for?\"

I was going thro a question in an assessment book and the answer given was just 'thousands', which meant it wanted the 'place', essentially different from '8000' or '8 thousands' which is the 'value'.

It also means that the question 'What does the digit '8' stand for?' is different from 'What is the place value of the digit '8'?'.

My apology. I have mixed up Daisy with Suling. Suling is the 1U and is 17. :salute:

I have amended my answer.

My understanding of English tells me 'thousands', 'eight thousands' or '8 thousands' or '8000' should be acceptable for both questions. Is it necessary to go so granular?

If you have a number 98765.

1.\tThe digit 8 is in the thousands place.
2.\tThe place value of digit 8 is 8000/eight thousand/8 thousand (normally advisable to write the number in numerical form)

Thanks Dharma,
So 1 answers \"What does digit 8 stand for?\"
2 answers \"What is the place value of digit 8?\"
