money calculations
Please can anyone help with the following:-
67 x £5.32 = £356.44
daughter got £37.24
can you please explain how to work this out so that I can relay to my daughter. Sorry if this seems really simple, but I just don't get maths at all.
Many thanks in advance

not easy for youngsters but have to decide whether the answer is "reasonable" ie nearly 70 times £5 must equal somewhere near £350.
Otherwise to get the exact answer comes down to however you teach kids to long multiplication, I may be able to do the sum but couldn't teach anyone to do anything (other than medical students ho ho).
I'm sure a maths teacher will advise soon....

I think the best way is start from whatever method your daughter uses at school for long multiplication (it probably depends on what year she is in, but is most likely "chunking" at this stage). If she can't explain her method to you, look in her maths exercise book to see what they do.
There are also some very useful websites which tell you the sort of methods they use in primary school maths today. If you look in the maths section of Advisory Service Kent (ASK) on the KCC website you will find some leaflets they have produced which explain methods commonly used in school today.
Also, there are lots of books on sale in a big WH Smiths which cover KS2 maths and the kind of methods they use in school today.
Good luck

Chunking is used for division - many schools use the grid method for long multiplication - this site might help:

It looks like your daughter worked out the 7 x £5.32 bit but forgot to calculate and add on 60 x £5.32.
To do this she would calculate 6 x £5.32 then put a zero on the end (because she's multiplying by a figure in the 'tens' column). She then needs to add the two figures together to come up with the final answer.
