If I am understanding your example (that seems to be different to the other responses so far)...

12
47

12+47+14+27 = 100 (as mentioned in the thread description)

Hence,...

14
27

14+27+12+47=100 (the same as above, but with digits tranposed)

Also…

23
18

23+18+21+38=100

Similarly, transposing digits...

21
38

21+38+23+18=100

I think you'll find you've copied my answer so not different to the other responses (insert old rolling eyes smiley here)

I think you'll find it took me longer to type out my text that you took to type your own & I probably started before you did, but submitted after you.

Check the times of the postings.

by copied i meant you'd done the same answer not seen my post then copied it, i was just pointing out your inaccurate use of the words "that seems to be different to the other responses so far"

Call me old fashioned but surely the idea behind homework is that your kids actually do it. A bit pointless if the parents do it.

Its better for them to get it wrong so the teacher can help them out rather than the teacher thinking they're all fine and ignoring them thus the kids falling even further behind.

It wasn't inaccurate when I started typing (probably) as I had not seen your response by then (as you had not submitted it).

After seeing what happened immediately after I posted, I thought about editing my original comment or posting a follow-up comment. I wish I had now so you could grasp the concept of two people typing concurrently. I convinced myself it wouldn't be an issue for everybody reading.

OK; well done... you posted your answer before me & contributed to the final result.

Assuming we both understood the question correctly then Textreme's daughter’s teacher will be happy.

You are old-fashioned! Kids can still get their homework wrong themselves, but these days the Internet gives them a selection of wrong answers to choose from (not just their parents' attempts).

Homework isn't for kids anyway. It is to remind parents how much they have forgotten since they left school.

I would hope the parent gets these answers and then points their child in the right direction :)
