Today, in maths extension, we learnt about about particians. Particians work like this.
The particians of 4 1+1+1+1
1+1+2
2+2
1+3
4
There are 5 particians for the number 4. Particians are the ways that numbers can add to a certain number. You can use as many numbers as you want but you can only add.
Now find out how many particians 9 has.
30 particians. btw, isn't it partition?
