Pascals triangle

We all know pascals triangle , we can use this in bionomial theorm ans yes guys we can very well use it in Compound intrest
0 1
1 1 1
2 1 2 1
3 1 3 3 1
4 1 4 6 4 1


let us take an example P =10000 R= 20% AT t= 0 P= ammount
at t= 1 10000 x 1 + 1 x 10000( .20)=ammount
so if after 3 years we need to calculate ammount
so it will be 1 x p + 3 x r% of p + 3 x r% of r% pf p + 1 x r% of r% of r% of p


njoy calculation guys

will come up with new post soon
