# Strange Mathematical Symbols

## 1. Omega

In number theory, Omega is the number of prime divisors of n. To find prime divisors you make a chart and divide n by a number and draw two lines leading to the dividend and quotient. Keep going until you have done as much of prime factorisation.

## 2. Golden Ratio

Golden Ratio or Golden Section is used in geometry, art, architecture etc. To find the golden ratio of a line, simply divide it into TWO pieces so that the longer part divided by the smaller part is the same as the whole length divided by the longer part.

## 3. PROPORTIONAL TO

Proportional To is when two quantities always have the same size in relation to each other. You can use ratio to find the difference. For example, when a metre of wood weighs 2kg and 2 metres of wood weighs 4kg. The ratio is 1:2. 1m=2kg 2m=4kg 3m=6kg ....

## 4. DELTA

Delta is the change in two or more constants or variable terms. For example
X-Y=Delta (Z) , Z is the difference of X and Y.

## Which symbol is the most relevant?

I think the most relevant symbol is the 'Proportional To' symbol because I understand how it works. In future I wish to work in medical field and I might use this symbol for measuring chemicals etc.

## Which symbol is the least relevant?

I think the least relevant symbol is the 'Golden Ratio' symbol because before I even searched for it, I didn't know that it existed and I found it uninteresting and something that I would not use at this stage. Even if I do like architecture, I am not particularly fond of the subject of geometry and I don't want a career related to art.

## Which symbol is my favourite?

My favourite symbol is the 'Omega' symbol not because it is the strangest but it is the most interesting. I enjoyed looking it up and tried to know more about its uses.

## Which symbol is the strangest?

I think the most strangest of all symbols is the 'Omega' symbol because it looks like many things depending on how you look at it. These are the pictures that I can see in the symbol:
A horseshoe
An open 'O'
The top part of a person's body [head to shoulders (without a face or hair)]
A part of a fish

I think it is very strange to see four or more things in one symbol which are not even related to the symbol.
