    I think Saf wants an explanation of what they actually are.

    4|2 = 42

    2 | 1, 3, 6, 8
    3 | 2, 6
    4 | 0, 5, 9

    This is an example of one. It helps to sort out data, which could ber useful when finding out quartiles, standard deviation etc. You have a set on unsorted data, and you put the tens in the 1st column, and the units in the 2nd (both in numerical order). You can do 2 separate stem and leaf diagrams, the 1st with the units put down as you see them in the given data, and the 2nd with the units in numerical order. At teh top you put a key, indicating the line which separates the 2 columns, and what it means. (See example)
    Hope this helps. (edited to hopefully make more sense)

    well it really should be "|" not "(" but besides that, going back to the example:
    4(2 = 42 <---that just means that 4|2 is 42 so generalising a|b means ab

    2 ( 1, 3, 6, 8 <----this therefore shows numbers 21, 23, 26, 28
    3 ( 2, 6 <------and so on
    4 ( 0, 5, 9 <-----and so on.

    So in this case "|" just separates tens from units.

    Sorry guys, should have explained. My keyboard isn't working properly (am gonna have a new one fixed in), so as much as I tried, I couldn't get the line, and therefore used the bracket. Maybe it would help if I placed an unordered (and made up) set of data 1st:

    36, 49, 21, 28, 49, 23, 32, 46, 40.

    Oh, by the way, when you've finished the stem and leaf diagram, check how many numbers you have in the given set of data, and in your diagram, as it's easy to miss out one or two.

    Also, in the key, 4|20 would represent 420, with the | separating the 100s and the 10s.
    (am able to use the | now, by copying and pasting it from the previous post.)

    Hey
    They are really easy and simple but difficult to explain. Ask your maths teacher. They are so unbelievably simplae to do and you can do them really quickly.

    He's doing his GCSEs, so he doesn't need to know all thi stuff. It is a pretty easy topic though, and I'M sure that even GCSE students would be able to understand about it if theY read about it.

    wanting to understand and not wanting to is very different
