Emma’s Dilemma

On this piece of mathematics coursework called Emma’s Dilema we are going to look at all the different ways that we can arrange names. On this piece of coursework I am trying to achieve to find all the different ways I can arrange names and also I want to find out a good enough formula so that i can find the different arrangements more easily.

Middle

SINOM

3 letters = SAM SIMNO

SMA SMNIO

ASM SMNOI

AMS SIMON

MAS SMION

MSA SINMO

SMOIN

Looked at LUCY SONIM

SOMIN

SOIMN

Conclusion

There are 5 letters in SIMONs name so what we do because there is 24 arrangements we times

24 x 5 = 120

So there are 120 arrangements in SIMONs name

Name | Number of Letters | Number of Arrangements |

JO | 2 | 2 |

IAN | 3 | 6 |

LUCY | 4 | 24 |

SIMON | 5 | 120 |

I am going to now investigate names with a repetition of a letter in them for

Example:

D,D = 1 , MUM = 3 , EMMA = 12 , KELLY = 60

I have found out that if a name with a letter repetition of 2, then it has half the amount of arrangements, where as a name without a repetition would have more letters.

This student written piece of work is one of many that can be found in our GCSE Emma's Dilemma section.
