Question about Texas Instruments TI-89 Calculator

Use the ^ key to insert a power (it's located above the division key) then put a negative power by typing the negative key (located at the very bottom right of the keypad next to the ENTER key) and then the number of the power.

10^-3

If this doesn't give the right result, put the negative power in parentheses. I can't remember off hand if you need to do that or not.

10^(-3)

To use the power, you use the y to the x key, above the EXP key. To enter 2 to the power of 4, you enter 2 hit the y to the x key and enter 4 and hit enter.

To use percent function, you enter the percent key after the number. To calculate Interest, where Interest = Principal x Interest x Time. For example, if the principal is $1,000, the interest rate is 8%, and time/term is 4 years, we would enter 1000 x 8 Percent x 4. When the8 is entered followed by the percent key, it should turn into 0.08.

Good luck,

Use the key labeled times 10 to power X, the one between the decimal dot ant the Ans keys, in the middle of the bottom row of keys.

10 to the power 0 is entered as 1. [x10^X] 9 or simply [x10^X] 9

To enter negative exponents use the change sign key [(-)] just above the [RCL] key

10 to -9 is entered as [x10^X] [(-)] 9 result is shown as 1x10-9.
