Hi There,
People I am in a fix, 1st of all being from a commerce background I suck at math.
Well my Gal friend is stydying for an exam and it has some exponential sums to solve. She is allowed a scientific calculator in the exam, the calcy she has is a Casio FX-991ES which looks like this.
We are both wondering how to solve these exponential sums, for example
So how do we go about doing this on the calcy we have got. Halp!! :huh:

Code:
Formula for calculating Compound Interest:
C = P (1+i)n
Where
C = amount
P = principal
i = Interest rate per conversion period
n = total number of conversion periods
Example:
Mr. X invested Rs. 10,000 for five years at an interest rate of 7.5%
compounded quarterly
P = Rs. 10,000
i = 0.075 / 4, or 0.01875
n = 4 * 5, or 20, conversion periods over the five years
Therefore, the amount, C, is:
C = Rs. 10,000(1 + 0.01875)^20
= Rs 10,000 x 1.449948
= Rs 14,499.48
So at the end of five years Mr. X would earn Rs. 4,499.48 (Rs.14,499.48 – Rs.10,000) as interest. This is also called as Compounding.
So how do we go about doing this on the calcy we have got. Halp!! :huh:
