What Has My Left Palm Got To Do With Math?

Palm Reading for my Destiny? Nope.

Our palms have the exponential graph y=e^x embedded on them! Now you have 1 less graph to take care of. Just ensure you keep your hands nice and clean so that the palm lines stay on for you forever.

When the need to draw y=e^x arises, flip that palm up :)

    To find the Total Amount based on Simple Interest, this is the formuale you can use:
    A_n=P(1+\frac{r}{100}n)

    An : Total Amount after n years

    P: Original Principal Amount

    r: Simple Interest Rate

    n: Number of Years

    To find the Total Amount based on Compound Interest, this is the formuale you can use:
    A_n=P(1+\frac{r}{100})^n<br>
