HELP ASAP Maths homework Y3 I can't work it out let alone dd

[lexcat]

Am I missing something as dd gave up and I don't seem to be able to do it.
There are four calculations in this diagram, three across and on down.

Use the numbers 1 to 9. Put a different number in each box. Each calculaton must be correct.

[ ]-[ ]=[ ]
.........X
[ ]&divid;[ ]=[ ]

[ ]+[ ]=[ ]

say what ?

You have 3 equations

A - B = C
D/E = F
G + H = I

A to I are the numbers 1 to 9. You need to work out which numbers go where.

Sorry that looks strange but all the are meant to be in line with each other. Couldn't get the divide and had to use the dots to line up X in the last column.
Any help would be greatful.

Oh, I've no idea what the dots and the X are.

I guess that C x F = I then.

Lex - Assuming Soupy's simplified presentation is correct, can you show us what the 4th calcualtion, ie the one going downwards, looks like?

it's a puzzle... just start by writing down A=1 B=2 C=3 and then try fitting them in the sums

9 can only be A or I.

Actually, if there's that multiplication one, 9 has to be A.

8-7=1
6 divided 3 =2

4+5=9

Try this,

6/3=2
9-4=5
7+1=8

Neither of those work if C x F = I

doesn't make sense to me sorry!

Sorry, forgot about the 4th calculation

The X is times and the dots I put there to try and get it in the right place in the last column.

C or F has to be 2.

9-5=4
6/3=2
7+1=8

C & F have to be either 2 and 3 or 2 and 4 don't they....? Ooo!
6/3 =2
9-5 = 4
7+1 = 8
2 x 4 = 8

if they cannot do it, you write a note telling the teacher so.

the teacher cannot possibly help your child learn if you do their homework.

this is what I do........if I cannot help, I tell the teacher and she appreciates it as it shows her that her method of teaching is not helping this particular child (in my case my DS2).

Damn you goblin! I was so proud of myself that I couldn't type fast enough to beat you!

9-5=4
6/3=2
7=1=8

It's basically a process of elimination and using logical thinking. I'm surprised it's Y3 homework though.

Thanks thats great I was so close I had the had the 8 but had 2 and 4 muddled with give dd one of the numbers for the boxes and see how she goes.

Sorry Marthasmama

Can someone set us another one - calculators at dawn

I would have been faster if I hadn't been so excited about getting it that I lost the ability to type! Maths is not really my thing so I was amazed. I suspect if another challenge was set, I would fail miserably!
