Question about Texas Instruments TI-30XA Calculator

# What buttons do I push to calculate continuously compounded interest on a TI-30XA? My professor said to push the e^x button, but it only results in an error.

I figured it out. I was inputting the information in the wrong order. For the problem "How much will be in the account after 3 years if you start with \$20,000 at a rate of 5.5% compounded continuously?" I had put in \$20,000 and hit the e^x button, when in fact, I should have put in the 5.5% times 3 years and THEN hit the button, then multiplied by \$20,000.

### How to make this operation in my texas instruments TI-30XA 3.55*10(to the 24)

Because this calculator does not allow you to enter formulas, you have to alter the formula a bit.

Instead of entering 3.55*10^24, enter (10^24)*3.55

Note: 10^24 is 10 to the 24.

Here is the procedure:
1) find 10^24. Do this by typing 10, pressing the yx button (which is right above the divide button), and then typing 24. Press the '=' button.

2) multiple the result by 3.55. Press the '=' button.
