# What are all of the numbers you could make with 6,1 and 2? watch

1. I’ve put a lot but this website has given me 2/3 marks so far
2. Is this for maths homework? We can't just give you the answer. What have you tried so far?
3. Can you repeat the digits or does it have to be each digit occurring once?
And is it including 1 digit and 2 digit numbers? Theoretically you could make numbers with infinite digits so I’m assuming it’s up to three-digit numbers?

You can only use it once because it’s one of those ‘John has 3 cards’ questions

Ah okay–is it a “how many ways can he order these three cards” type question then? It might be easier to just send a photo of the question

Please can you post the question in full then show us all the possibilities that you have found?

Here’s the question:

John has these 3 cards (6,1 and 2)

Make a list of all the numbers he can make using the cards

Check above ^^

Please show us the list of numbers that you have worked out. It doesn't matter if you're wrong.
10. this is basic primary school maths

just order the numbers in as many ways as you can
11. There are 3 factorial different orders, now you just have to find them.

I have but there is something I’m missing.

I’ve put:

612
621
162
126
216
261
9
3
6
1

This has somehow managed to get me 2/3 marks even though I’ve used 3 different ways of making numbers
14. If you are familiar with factorials, as the person above said, you can use them to find the number of possible solutions you’re looking for (if not, don’t worry!)

You could use a probability tree structure if you want a fairly ordered way of finding all the 3-digit combinations

I assume you can work out all the 1 and 2 digit combinations easily enough?

Edit: out of interest what school year are you in?

You seem to be adding/subtracting the numbers? Is there a reason why you're doing this?

The question seems to indicate that you need to list the numbers that could be formed with the digits on the three cards. Unless there's part of the question that you haven't posted....

Also, what about 2 digit numbers like 61 for example?

I’m in year 11. I know this seems like primary school stuff but it’s just this ONE question on this maths website with 1 mark that I’m off.

I’m just trying all possibilities. I tried all of the 2 digit numbers but that just took off marks for some reason 😬

Please list all the numbers that you found without adding/subtracting or doing anything else.
19. GUYS never mind I finally figured out what I was doing wrong. 👍🏼

Great. When I saw a 7 in your list of numbers I thought you might have been trolling
