Here as you can see there are 24 different ways of arranging the name Lucy. A quicker way of writing this down would have been to see how many arrangements you could make by leaving L as the first letter. There are 6 when structured like this. After you have all the L ways are worked out, then just times that number (6)

To investigate the number of different arrangements of letters in a different words
x 2 = 6, the number of different arrangements. In a 4 letter word, to work out the amount of different arrangements you can do 4 x 3 x 2 = 24, or you can do 4! which is called 4 factorial. I found this out in the school library which is the same as 4 x 3 x 2 but times 1 but this make no difference to the result. This means that the formula for the number of arrangements for a word with no repeated letters is: n!

Investigate the number of arrangements of Dave's name.........
Number of letters Number of arrangements Calculation 2 2 1x2 3 6 1x2x3 4 24 1x2x3x4 5 120 1x2x3x4x5 6 720 1x2x3x4x5x6 7 5040 1x2x3x4x5x6x7 From this I have concluded that the formula n! is correct( n representing the number of letters). Therefore, to find the number of arrangements for six letter word, you would multiply the number of letters (6) by the number of arrangements of the previous number (120). This gives seven hundred and twenty arrangements. I then tried to simplify this.

combinations 5 Letters different ANDIE ANDEI ANEDI ANEID ANIDE ANIED ADNIE ADNEI ADENI ADEIN ADIEN ADINE AIDNE AIDEN AIEDN AIEND AINED AINDE AEIDN AEIND AENID AENDI AEDNI AEDIN So far I have 24 combinations. All combinations begin with 'a' . As previous results have shown the combinations beginning with the following letters. Either e d n or I will each give 24. Therefore for the total number of combinations all I need to do is multiply 24 by 5. This gives a total of 120 different combinations for the fiveletter name, with all letters different 120.

Compare and contrast the fictional letters in 'Birdsong' with the real letters written to Vera Brittain by Edward Brittain and Roland Leighton. Which do you find more moving and powerful and why?
In 'Weir's' letter the first thing he says is "We are going to attack." As readers we know how horrific the battle was, so immediately we can sense the naivety and the blindness of his character. In all the letters, there is a constant repetition of this. 'Stephen' is the only character who can see the premonition that "some crime against nature is about to be committed." His letter is the only one, which shows negativity towards the war. He is sending his letter to 'Isabelle,' fully aware that she may not receive it.

The above arrangements show the first 24 arrangements for the fiveletter name CAINE. The first 24 arrangements all Have the letter C in the front and in this same way if I was to carry on every other letter would come to the front and therefore there would be 24 x 5 arrangements, which is 120.

I am doing an investigation into words and their number of combinations. I will find formulae and work out the number of combinations for the words.
5 different letters 120 1x2x3x4x5=120 or 5! =120 I will now prove that 5 different letters has 120 combinations: ABCDE=24 ABCED=24 ABECD=24 AEBCD=24 EABCD=24 Total=120 I worked out the formula was n! after first discovering the pattern was 1x2; 1x2x3; as so on. From prior knowledge I knew an easier way to write this was n! or n factorial. The factorial pattern is: 1!=0x1=1 2!=0x1x2=2 3!=0x1x2x3=6 4!=0x1x2x3x4=24 Now I will draw a graph to show that I have got the right formula and to see the relationship between the number of combinations and the number of letters even more clearly than in a table.

Hopefully when I have rounded them all together I might be able to work out a recurring pattern.

JJ JJ JJ is a letter name and both of the letters are the same; therefore there is only 1 combination of this name.

Emma's Dilemma
This is because I have noticed something as I was working out the ?. I have found that I was going to repeat everything I was doing 4 times. Similarly, I have realised that I was doing every thing 3 times for the second letter, twice for my third letter and once for my last. Hence, I could say that to work out the ? for a four letter word, I am merely multiplying 4*3*2*1 and this gives me 24, which is the correct answer. I could express this as 4!. Could I however say this for words made up of a different amount of letters?

To investigate the combination of arrangement of letters in Jeans name and then for her friend Emma.
E A M A M M E A M E M A E M M My Prediction was incorrect because although there are 4 letters in Emmas name 2 of them are the same. So there are less combinations. Now I will try some names of my own to check the combinations are always the same for names like these. POLO: I predict there will be 12 combinations because 2 letters are the same.

Table of Results Number of Letters Number of Different Arrangements 2 2 3 6 4 24 From the first two results the amount of different arrangements possible appears to be double the number of letters in the word. Looking at the results of the 4letter word it appears that this does not apply to them all. Therefore I believe it may have something to do with the number of letters but, be higher as the number of letters increases rather than just doubling.

I.E. The possible arrangements for a 5 letter name with no repeats is (24x5) I shall now test my hypothesis: JAMES JAEMS JASEM JASME JAMSE JAESM JSAME JSMEA JSMAE JSAEM JSEAM JSEMA JMASE JMAES JMESA JMEAS JMSAE JMSEA JEAMS JEASM JESAM JESMA As there is five letters in the name James there will obviously be 120 arrangements as there is 24 for each letter JEMAS JEMSA Just as I had predicted there are a possible 120 arrangements for a five letter name with no repeats. Now I have proved my original hypothesis I shall now do a table of results: Table of Results Number of Letters Number of Different Arrangements 2 2 3 6

Emma's Dilemma  Rearranging Emma's Name in different permutations
That's twice as many as EMMA, which has 4 letters and 3 different. I have noticed that with Lucy there are 6 possibilities beginning with each different letter. For instance there are 6 arrangements with Lucy beginning with L, and 6 beginning with u and so on. 6 X 4 (the amount of letters) gives 24. From these 2 investigation I worked out a method: I used numbers to represent the letters, Step1: 1234Do the last two number first then you get 1243. 1243Do the last three numbers and try the possibility. 1423.

4 letters all of them different. I have worked that this is double to EMMA. I have also worked out that with every 2 letters beginning they are 12 combinations so with every one letter beginning they are 6 different combinations. I will now try 5 letters and find out how many different combinations they are. I predict that they will be 120 different combinations. I predict this because they is 24 combinations for PHIL so if you added another letter you could put the new letter at the beginning of each combination.

The same rule applies to the letters "U", "C" and "Y" in the name Lucy. Overall there are 24 different combinations for the name Lucy From the first two experiments I have noticed that the name Emma has half the number of combinations when compared with the name Lucy.
