Note: |after APD retrieves display, pending operations, settings, and memory. TI-30Xa Solar ¦ To turn on the TI-30Xa Solar, expose the solar panel to light and press !. Note: Always press !to clear the calculator because memory and display may contain incorrect numbers. ¦ To turn off the TI-30Xa Solar, cover the solar panel with the slide case. 2nd Functions 2nd functions are printed above the keys. "selects the 2nd function of the next key pressed. For example, 2 "tcalculates the cube of 2. 2 Results Results The calculator can display up to 10 digits plus a minus sign (-9,999,999,999 through 9,999,999,999) and a 2-digit exponent. Results with more than 10 digits display in scientific notation. Basic Arithmetic D>82 60 D5 812 J 120. J Completes all pending operations. With constant (K), repeats the operation and value.
