### I need to use the exponential function with a negative exponent on my TI-30XIIS. I hit 2nd then e^x button, but when i input a negative exponent I get an error. Help please!

I think what you did was use the minus sign instead of the negative sign, on that calculator, the two are not interchangeable. I purposely used the minus sign just now and also got a syntax error, but it looks like it works with the negative sign (-) located under the 3 button.
